Century Modern 0:11 inventors like Elon Musk started putting 0:14 these AC induction Motors into electric 0:17 cars from this Tesla Motors was born 0:20 Elon musk's Tesla has been constantly 0:23 improving on that Century old design 0:25 from their Model S to the model 3 and 0:27 onto their next generation electric car 0:30 that has yet to even be released this is 0:34 how Tesla reinvented the electric 0:40 motor the AC induction motor is a The AC Induction Motor 0:43 product that goes back to the early days 0:45 of Tesla Motors and the development of 0:47 their first Roadster vehicle but in the 0:49 grand scheme of things the induction 0:51 motor actually tracks its origin back to 0:54 the early days of the Industrial 0:56 Revolution alternating current is the 0:58 kind of electricity that surrounds us on 1:01 a daily basis it's what comes out of the 1:03 sockets in your wall and moves through 1:05 the power lines up and down your street 1:08 Nicola Tesla is widely considered to be 1:10 the father of alternating current 1:12 electricity and was a pivotal figure in 1:14 adopting AC to power the US electrical 1:17 grid around the turn of the 20th century 1:20 many people consider Tesla's greatest 1:22 invention to be the alternating current 1:24 induction motor essentially a device 1:26 that will transform AC electricity into 1:28 mechanical motion and and in turn when 1:30 used in the opposite direction an 1:32 induction motor can turn motion into 1:35 electricity one of the first large scale 1:37 applications of Tesla's AC generator was 1:39 capturing hydroelectricity at Niagara 1:42 Falls when we say alternating current we 1:45 are really talking about the direction 1:46 that electricity is moving through a 1:48 circuit so for AC electricity to work 1:51 the direction of the electric current 1:53 has to continuously alternate between 1:55 forwards and backwards this is a bit 1:59 difficult to imagine in the context of 2:00 our own electrical grid as far as we can 2:03 tell electricity flows out of the 2:05 Generating Station and into our house 2:07 but in reality it's in a constant state 2:10 of movement back and forth this is a 2:13 characteristic that allows AC 2:15 electricity to be transmitted at high 2:17 voltages over very long distances and 2:20 then converted into lower voltage for 2:22 final delivery to the consumer the 2:25 alternating flow happens so fast that we 2:27 only perceive the electricity as con but 2:30 in reality the direction of electricity 2:32 alternates 60 times per second in North 2:35 America so how does this apply to How Induction Motors Work 2:37 electric motors well it's all about 2:39 magnets so when you transmit electricity 2:41 through a conductive material like a 2:43 copper wire you also create a magnetic 2:46 field in that wire this is an 2:48 electromagnet and once you stop the flow 2:50 of electricity the magnetic field will 2:53 also dissipate now if you transfer 2:55 electricity in one direction through a 2:58 conductor you create a magnet magnetic 3:00 pole either a South Pole or a North Pole 3:02 and then if you were to reverse the flow 3:04 of electricity through that same 3:05 conductor you would also reverse the 3:07 polarity of the magnetic field so as the 3:10 direction of electricity alternates so 3:12 does the North and South Pole of the 3:14 electromagnet there are two essential 3:16 components of an electric motor the 3:18 stator and the rotor the rotor rotates 3:21 and the stator remains stationary easy 3:23 way to remember which is which now as 3:25 the name suggests an induction motor 3:27 uses a rotating magnetic field in the 3:30 stator to induce a rotational force in 3:32 the rotor here is how that breaks down 3:35 your stator is essentially a ring of 3:37 copper wire that is arranged into coils 3:39 that run from the front to the back of 3:41 the motor each coil of wire is wrapped 3:44 around a piece of iron so when 3:46 electricity is flowed through the coil 3:48 of wire it becomes a powerful 3:50 electromagnet the polarity of each 3:52 magnet is determined by the direction of 3:54 current so by alternating the directions 3:56 of the electrical charge being applied 3:58 to each sub sequent winding and flipping 4:01 each polarity in sequence we create a 4:04 rotating magnetic field that travels 4:06 around the Ring of the stator the speed 4:09 at which the magnetic field rotates can 4:11 then be controlled by the rate at which 4:13 you can alternate the flow of 4:15 electricity the rotor in this case is a 4:17 much more simple component there are 4:19 various different kinds of rotors used 4:21 in different induction motor designs but 4:23 the one that we are going to focus on 4:24 today is known as the squirrel cage 4:27 rotor it gets the name because the 4:28 structure is aind cylinder made from 4:30 aluminum bars that run from the front to 4:32 the back of the rotor with circular 4:34 metal end caps there is no supply of 4:37 electricity flowing into the rotor and 4:39 it contains no natural magnets it's 4:42 literally just a metal cage that can 4:44 freely rotate and yet the rotor can be 4:46 transformed into a magnet by the 4:48 rotating magnetic field of the stator 4:51 one of the interesting things about 4:52 magnets is that they move relative to a 4:55 conductive material they can induce an 4:57 electrical current into that conductor 4:59 which in turn creates an electromagnet 5:02 with no contact required just relative 5:05 motion you can see this by dropping a 5:07 magnet straight down a copper pipe as 5:09 the magnet Falls it will induce a 5:11 magnetic field into the pipe which will 5:13 then work against the magnet itself and 5:15 slow the fall of the magnet through the 5:17 tube so the further it falls the slower 5:20 it will move through the air due to 5:21 resistance from the induced magnetic 5:23 field in the copper pipe the same thing 5:27 is happening inside the induction motor 5:29 by rotating the magnetic field around 5:30 the stator using alternating current and 5:32 electromagnets a magnetic field will be 5:35 induced in the bars of the sroll cage 5:36 rotor that induced magnetic field will 5:39 react against the magnetism of the 5:41 stator we know that magnets with the 5:43 same polarity will push against each 5:45 other and this force of magnetism will 5:47 cause the rotor to turn in the direction 5:49 of the stator's magnetic field So the 5:52 faster you alternate the flow of current 5:54 through the stator the faster the 5:55 rotation of the magnetic field and the 5:58 faster the movement of the rotor due to 6:00 the magnetic push effect the only caveat 6:03 we need to remember is that the rotor 6:05 will have to move at a slower rate than 6:07 the rotating field of the stator because 6:09 the magnetic field is created by 6:11 relative motion if the two are turning 6:14 in sync then there's no longer any of 6:16 that motion in play the rotor will 6:18 demagnetize and slow down from the time AC Induction Motors 6:21 this induction motor was first patented 6:22 by Nicola Tesla 1888 to the present day 6:26 AC motors have been a staple of 6:28 industrial society we see them in 6:31 everything from elevators and street 6:32 cars to ceiling fans and washing 6:34 machines anything that plugs into the 6:36 electrical grid and Spins is more than 6:39 likely to have an AC induction motor 6:41 inside so when it came time for Elon 6:43 Musk and his crew of Founders at Tesla 6:45 Motors to choose a power source for 6:47 their first electric Roadster vehicle 6:49 there was one very obvious candidate the 6:52 AC induction motor and when used in an 6:55 electric vehicle the design gives you 6:56 one significant Advantage we know that 6:59 when you rotate the magnets of the 7:01 stator faster than the rotor you 7:03 Electrify the rotor and create a magnet 7:05 but when you spin the rotor faster than 7:07 the stator using an external Force like 7:10 a wheel you Electrify the stator which 7:13 can then transfer the excess energy back 7:15 to the battery pack and increase the 7:17 driving range of your vehicle this is 7:19 how regenerative braking Works Tesla 7:22 retained the AC induction motor as their 7:24 primary drive unit into the model S and 7:26 X this allowed the relatively large and 7:29 heavy vehicles to achieve mindboggling 7:32 Feats of acceleration from a standing 7:34 start but they also came with a 7:36 significant drawback that needed to be 7:38 solved so the beauty of the AC induction 7:41 motor is its Simplicity coils of copper 7:44 wire some chunks of steel and iron a 7:46 squirrel cage of aluminum bars not much 7:49 to it that's exactly why the motors in 7:52 appliances like air conditioners and 7:54 washing machines can run for decades 7:56 without failure the downsides of the 7:59 orig induction Motors start to show 8:01 themselves only when you go in search of 8:04 maximum power and efficiency which is 8:06 exactly what Tesla was looking for when 8:08 they designed their model 3 okay so Permanent Magnet Motors 8:11 everything that we just talked about 8:12 still applies to this new motor that 8:14 Tesla created for their model 3 but with 8:17 one key addition permanent magnets 8:21 specifically they added permanent 8:22 magnets to the rotor so now instead of 8:24 an aluminum squirrel cage we have this 8:27 dense iron core filled with strips of a 8:30 magnetic Rare Earth element called 8:32 neodymium the technical name for this 8:34 new motor type is IPM syrm that means 8:37 internal permanent magnet synchronous 8:39 reluctance motor it's complicated here's 8:43 the scoop you could make a permanent 8:45 magnet motor by taking a metal cylinder 8:47 sticking four magnets to the outside 8:49 with South poles on the top and bottom 8:51 and North Poles on the sides that would 8:53 be your rotor and then when you stick 8:56 that inside the stator that we talked 8:57 about before and start rotating the 8:59 electromagnetic field in the stator 9:01 coils your permanent magnet rotor will 9:03 follow now we can actually spin the 9:06 Rotor at the exact same speed as the 9:08 rotating magnetic field of the stator 9:10 because we are no longer relying on 9:12 relative motion to induce the magnetism 9:15 in the rotor this already gives us 9:17 higher efficiency and more power 9:19 particularly when accelerating from a 9:21 stop because we have these two very 9:24 powerful magnetic fields that can 9:26 instantly push off from each other but 9:29 there's a big problem two problems 9:31 really for one permanent magnets stuck 9:33 to the outside of the rotor will have a 9:35 tendency to come unstuck due to 9:38 centrifugal force So the faster the 9:40 rotor spins the more likely it is to fly 9:43 apart but even more importantly reason 9:45 two is that the rotation of the 9:47 permanent magnets will start to induce 9:49 their own magnetic field into the stator 9:51 coils at high speed and this is going to 9:54 be opposite to the electromagnetic flow 9:56 in the stator and that force is going to 9:58 want to slow down the whole system this 10:01 is called back EMF and the faster the 10:04 rotor speed the more back EMF you get to 10:07 combat these two downsides we introduced 10:09 the design of a reluctance motor so 10:11 aluminum and copper are only magnetic 10:14 when you flow electricity through them 10:15 but iron is naturally attracted to 10:18 magnetic fields so that means we can use 10:20 it as a rotor material inside our same 10:23 old electromagnet stator and that iron 10:25 rotor will follow in sync with the 10:27 rotation of the stator's magnetic field 10:30 again there is one caveat we need to cut 10:33 channels into the iron material that 10:35 line up with the shape of the magnetic 10:37 field that surrounds it this will align 10:40 the magnetic reluctance of the iron core 10:42 with the magnetic field of the stator 10:44 and allow them to rotate in sync this is 10:47 our synchronous reluctance motor it's a 10:50 very efficient motor design and it works 10:52 very well at high speed because there is 10:54 no back EMF created by the iron rotor 10:57 the downside here is that a reluctance 10:59 motor has very low power density when 11:02 accelerating at low speed because the 11:04 rotor can only follow the rotating 11:05 magnetic field of the stator you don't 11:08 get that instant push effect of two 11:10 magnetic fields working against each 11:12 other now all we need to do is add 11:14 magnets to the rotor and we get our 11:16 perfect combination those channels that 11:18 we cut into the iron core make the ideal 11:21 location for our permanent magnets to 11:23 live this is our internal permanent 11:26 magnet by placing them inside the iron 11:28 rotor we reduce the permanent magnets 11:30 effect on the stator windings and 11:32 thereby reduce the problem of back EMF 11:35 now there is still a very complex task 11:37 here that involves balancing the 11:39 reluctance effect of the iron core with 11:41 the magnetic push of the permanent 11:42 magnets you see you want to utilize the 11:45 power of permanent magnets during 11:46 acceleration but then cancel them out 11:49 and switch over the efficiency of 11:50 reluctance at cruising speed this is all 11:53 handled by very Advanced software 11:55 controlling the magnetic field of the 11:57 stator that we cannot even begin to 11:59 explain and this is why the IPM sin RM 12:02 motor was never widely used until Tesla 12:06 came along and now Tesla is about to 12:08 take this design to the next level with 12:12 the motor design for the model 3 Tesla 12:14 was able to maximize both power and 12:16 efficiency but it did come at a cost if 12:19 we remember back to the original 12:21 induction motor it came with a 12:22 relatively simple and cheap rotor made 12:25 of aluminum Bars by switching to IPM sin 12:28 RM Tesla introduced The Rare Earth 12:30 element neodymium into their rotor so 12:33 the cost in this instance is money it's 12:36 a much more expensive motor now Tesla is 12:39 dedicating their research and 12:41 development into a Next Generation 12:42 vehicle platform that is supposed to 12:45 dramatically reduce cost while 12:47 maximizing efficiency this will serve as 12:50 the base for their upcoming Robo taxi 12:52 vehicle from what we learned last year 12:53 at Tesla's investor day the designers 12:56 are achieving much of that cost 12:57 reduction by elim ating Rare Earth 13:00 elements from the motor's composition 13:02 now it's not that neodymium is 13:03 particularly scarce in the overall 13:05 composition of the Earth but it is 13:07 difficult to locate near the surface and 13:09 you typically won't find large 13:11 concentrations all in one place so 13:13 therefore the cost is relatively High 13:16 and the supply is relatively low but 13:19 Engineers still prefer neodymium for 13:20 electric motors because it has a strong 13:23 magnetic field that won't degrade over 13:25 long periods of use so it does justify 13:28 the cost 13:29 now Tesla is saying that they can get by 13:31 without the need for any Rare Earth 13:33 elements in their new magnets so what 13:35 will they use instead a widely popular 13:38 material for making magnets is called 13:40 ferite this is a ceramic material of 13:43 mostly iron oxide also known as rust 13:46 combined with additional metals like 13:48 manganese nickel and zinc but it doesn't 13:51 particularly matter which one you'd find 13:53 ceramic ferite magnets in everything 13:55 from speakers to electric guitars and 13:57 cordless drills they also help keep your 14:00 refrigerator door closed so it's a very 14:02 common and affordable material the 14:05 downside of fite compared to neodymium 14:07 is magnetic strength you would need a 14:09 much larger quantity of ferite to match 14:12 the strength of a neodymium magnet and 14:14 there's not much extra space to go 14:16 around inside an electric motor we know 14:19 that Tesla can make some of this back by 14:21 increasing efficiency they've done that 14:23 in the past just in the time between 14:25 model 3 and model y the engineers were 14:27 able to reduce the amount of rare earth 14:29 material required for the electric motor 14:31 without sacrificing any power but 14:33 inevitably by switching over to a farite 14:35 magnet Tesla will lose some performance 14:37 in their nextg vehicle so now instead of 14:40 going 0 to 60 in 6 seconds it might take 14:43 8 or 9 seconds is that the end of the 14:45 world absolutely not this is a vehicle 14:48 made for mass transportation not the 14:50 racetrack going all the way back to 14:52 Nicola Tesla good inventors are simply 14:55 trying to extract more functionality 14:57 from the world around them how can we do 14:59 more work with less energy how do we 15:01 combine different principles to create 15:03 something new and more effective and 15:06 that is what Tesla the company has 15:08 continued to do throughout the past two 15:09 decades The Tesla Space

Most scholars suggest that the Industrial Revolution was between 1750 and 1850. Mechanisation, steam engines and telegraphy played a part in the American Civil War which was 1861-1865. The "early stages" of the Industrial Revolution is categoriesed by water wheels, cotton mills and standardisations 30 Reply 3 replies @nufosmatic 4 months ago The reason that Westinghouse succeeded with AC and Tesla over Edison and DC was that he had Steinmetz to make mathematical sense out of it. Charles Proteus Steinmetz (is that a kuel name, or what?) was able to understand the AC systems that Tesla intuitively built and create tools for the analysis of synchronous AC systems. AC analysis, also known as Steinmetz Analysis by people who don't care to repeat history, allows you to predict the losses through a network of connections and design transformers to lessen these losses in a large system. 30 Reply 2 replies @jonasgschnell4051 3 months ago The internal magnets don't reduce back emf, besides centrifugal forces, the reason for putting them inside the rotor is the reduced Airgap. 13 Reply 1 reply @rogerstar6683 4 months ago While he's the face of the electric-car maker today, Elon Musk DID NOT START TESLA.

While the oblivious are like "thanks for misinforming me so clearly". 😂 40 Reply @freeenergytransformer5842 1 month ago Tesla's reinvention of the electric motor has been nothing short of revolutionary, building on the foundational work of Nikola Tesla and pushing the boundaries of what's possible in automotive technology. By leveraging Li-Ion batteries, which support higher current and enable the remarkable acceleration Tesla vehicles are known for, they’ve set a new standard in the industry. It's fascinating to see how Tesla opted to accelerate their innovation cycle by letting real customers essentially beta test their vehicles, a bold move that contrasts with traditional automakers who typically conduct extensive, multi-year testing before releasing a product. While this approach has its challenges, especially for engineers and designers working under intense pressure, it’s also what has allowed Tesla to lead the charge in electric vehicle innovation. 3 Reply @WalterWeinzinger 2 months ago The graphic at 2:45 is quite misleading. It looks like the magnetic field, generated by a current flow in a wire, runs lengthwise down the wire and then externally back to the other end of the wire. The magnetic field generated by current in a conductor actually rotates perpendicularly AROUND the wire according to the Right Hand Rule. 4 Reply @stevesepka2542 1 month ago Also, I've been told Elon Musk was not a founder of Tesla.

The difference in speed between that of the magnetic field produced by the rotor and the rotor itself is called displacement speed. 7 Reply 3 replies @Smartiezs 4 months ago i'm so glad i invested in those robotaxis you spoke of, totally got my money back in a year 2 Reply @charlesc266 4 months ago Well done to Toyota for the development and introduction of the IPM-synRM motor back during 1997. 3 Reply 1 reply @albrigo 1 month ago Tesla reinvented the electric motor, while SpaceX reinvented the rocket engine: sometimes there are some game changer people emerging in the society who are crazy enough like Elon Musk! 1 Reply @BillMitchell-lm8dg 4 months ago The depiction of magnetic lines of force that are generated by electrical current (and vice versa) are consistently wrong in all the renderings/animations in this video.

The rough gear shifts, the sound of the engine revving, and the direct connection to the road offer a unique driving experience that can't be replicated by the smooth, almost sterile feel of an electric motor. Even after driving a Tesla Model 3, with its instant torque and speed, the pull to get back behind the wheel of a car like the 280zx is undeniable. There’s something about that "notchy," mechanical feeling that brings a sense of satisfaction, even if the performance numbers don’t compare to modern EVs. It’s more about the journey and the emotional connection to the machine, rather than just the speed. 4 Reply 2 replies @MikkoRantalainen 4 months ago (edited) 2:20 I think it would have been good to mention that you could transmit lots of power using DC transmission network, too. The problem with DC network is that when you need to step down the voltage, you cannot do it with a static pair of coils and some non-movable iron (which is all you need for AC transformer – zero moving parts, zero logic, zero computers) but you need active components which increase the cost a lot. Multiply that with all the transformers you can see around and you can quickly figure out why AC is used. 9 Reply 2 replies @jarongaus 3 months ago Great explanation, very well done !!! 1 Reply @evisoneym2323 4 months ago We had missed your voice man 12 Reply @amsterdamn4829 2 months ago (edited) Best explanation ever... lovely video.

Years ago I translated sales materials about Mitsubishi Electric's traction motors for electric trains, elevators, etc. Now I understand them much better! Interestingly, the Japanese engineers calculated that for a new subway line in Osaka, it would be cheaper to "unroll" the electric motor, with a flat pad of coils on the train (the rotor) and, on the tracks, a thick flat horizontal steel plate called a "reaction plate" replacing the stator. Despite all the extra steel needed for the reaction plate, the lower riding cars from this design saved on tunneling costs. 10 Reply The Tesla Space · 3 replies @TheEducat0r 4 months ago Watching Tesla reinvent the electric motor is like watching history in the making. 1 Reply 2 replies @bobdeverell 2 months ago Hungarian Otto Blathy arguably invented the key components for AC use.

Elon Musk did not put the electric motor in Tesla. He joined a company named Tesla. They already had a vehicle and it was electric. Other than that great job! 23 Reply 3 replies @RY-TIOUSRY 1 month ago Tesla was able to conceptualize AC power in his mind. He was known for his extraordinary ability to visualize complex systems and processes. His invention of the induction AC motor is a testament to his unique mental capabilities. The idea of a rotating magnetic field, which is the core principle behind the induction motor, is believed to have come to him in a sudden flash of insight. This suggests a powerful ability to visualize and manipulate abstract concepts. While we can't definitively prove how Tesla conceived of AC power, his contemporaries described him as a visionary with an unparalleled ability to imagine and develop complex inventions. The evidence points strongly to the conclusion that his mental imagery played a crucial role in his groundbreaking work. 1 Reply @Suzanne-p9q 2 months ago Thanks u so very much you don't know how you have helped me and My family ️ Reply @LakbayFilipinoy973 4 months ago You're truly a great professor!

A large scale version would definitely be interesting . Reply @eddiegardner8232 4 months ago Much of the pleasure of driving a Tesla comes from the high torque and instant acceleration of its rare earth motors. These materials can of course be recycled as the number of EVs reaches its peak, just as can its aluminum body and internal aluminum castings, and the materials in its batteries, so "used" does not mean "consumed" like petroleum products burned as fuel. If Tesla, or any other manufacturer, wants to make EVs that are as slow and unresponsive and inefficient as today's 4-cyl ICE clunkers, then, no sale, for me. 13 Reply The Tesla Space · 10 replies @aienthusiast618 4 months ago probably one of my favvorite vids on this channel 2 Reply @makeit2132 4 months ago You forgot the key role of George Westinghouse...making Tesla invention useful and defeating Edison's DC 14 Reply 12 replies @silverco68 4 months ago jesus wept, Poly Phase induction, hypolite needs to be recognised. 3 Reply @SKRTV-n6f 1 day ago Очень хорошее видео.

Reply @steveoshaughnessy3736 2 months ago I enjoyed this video very much. My only criticism is people generally confuse voltage, current, and power. Yes, current flows both ways into and out of the power station. That is the C in AC, Alternating CURRENT. But the POWER or energy flows out of the power station to the consumers. With AC it is easy to step the generated voltage way up. I believe to Millions of volts. The current goes down (with a fixed load/resistance), and little energy is lost in the transmission from generator to consumer. The voltage is dropped back down at the consumer. That top wire between the poles running through your neighborhood have around 5,000 volts. Those gray or black cans on the polls are transfomers that drop that 5k Volts down to 220V for each house. Absolutely, Tesla's genious was in understanding how voltage and current can be altered by simple, passive transformers. Reply @Komin-Kun 1 month ago The Nissan LEAF: WHERE'S MY CREDIT MAN!?

The rotor is similar to the rotor in an automotive alternator, where the rotor coils are energized through a direct current sent to them via slip rings and brushes. Although the slip rings and brushes comprise a wear element, the efficiency of a wound rotor and its available torque overrides the effect of having a wearing part.

Reply @DavidCraig-go1zv 3 months ago (edited) Maybe in another 100 years you can try what's already available and more efficient. You can make a hybrid of a motor and generator to function as a single unit. One unit can be used to start others. Since the coils of wire will short out when the hybrid is hit by lightning, you throw them away and replace them with a solid copper (motor) ring. Next, you need coils that will generate electricity, but in order to make room for them, you have to eliminate the shaft and replace it with a solid copper (generating) ring. Next, a free-floating 'S' shaped arm in the center is put inside the hollow copper disk. When lightning hits the 1st completed disk the electromagnetism will protect all parts from the heat. The free-floating, copper 'S' will repel off the bottom, top and sides. As it spins, it will generate electricity in the top and bottom disks then move to the outer 'motor' ring. Thermodynamics will not affect the electro-magnetic field and the only moving part rides on electromaglev bearings. Reply @barnowl6807 4 months ago Ferrite is a good possibility despite it's disadvantage of being brittle and of relatively low flux density. First, Tesla has developed the motor with a very tightly constrained rotor. That would take care of brittle. Flux density is pretty well fixed by the material, but the volume of material would make up for much of this problem. And all of it workable because of the constrained rotor. And -- it would cost a lot less than super magnets.

Tesla never invented the transformers either - that was done by his employer brilliant George Westinghouse who was introvert and didn't need the personal publicity that Tesla desired. Probably Tesla's depression was related to his fake celebrity inventor status conflicting with his inadequacy in delivering while competing with some brilliant inventors. 4 Reply 2 replies @WJV9 4 months ago Permanent magnet motors and synchronous reluctance motors have been around for decades and therefore Tesla had nothing to "Re-Invent" they just took advantage of designs that had been developed for robotics and automation devices. Also you keep referring to induction motors as having a rotor made of aluminum bars formed into a cylindrical 'squirrel cage'. What you fail to mention is that the aluminum bars are pressure die cast into a 'laminated iron rotor' which is necessary since any 'air gap' will reduce the magnetic flux density which will cause lower power/torque and loss of efficiency in the motor. The laminations are electrically insulated from other laminations to prevent eddy current losses in iron rotor and stator. There are also 'Switched Reluctance' motors that have efficiencies similar to permanent magnet motors but SR motors don't need any magnets on the rotor. They do have vibration and noise issues however and more design improvements need to be made before they are usable in automobile power applications.

Reply @br7485 2 weeks ago Tesla is very far from being the greatest inventor of all time. His best invention is actually a straightforward one, more close even to dumb inventions. He assembled and assessed the DC motors of Edison and it is a very straightforward thing for anyone to notice that the electricity produced by these motors (in generator mode) had 2 sine components according to two coils, and that it would be better to transfer these component currents to the clients in sine form, where they can be again consumed by the coils of a motor (in engine mode) or by some appliance. Reply @daniell1869 1 month ago Video is misleading. Elon didn't invent Tesla 🙄🙄 1 Reply @jim.franklin 2 months ago As an electrical engineer with over 40 years experience I have to say I found this video very painful to both watch and listen to. There are so many "facts" that are simply wrong I cannot possibly list them here. The understanding of EMF and Back EMF is laughable, claiming that passing electricity through an aluminium or copper wire makes it magnetic is pathetic and wrong, plus, no mention of electric fields - without which none of this works at all. Lastly, Tesla was not the most successful inventer of all time - that goes to Thomas Edison who has 1093 patents to his name, over 800 were commercially successful in their own right or as part of another machine. In the modern world, the records for patents are held by companies, most of them biotechs. Reply @Achim188 3 months ago Sorry, but a PMSM ( Permanent Magnet Synchronous Motor) is not an invention of Testa! Moreover is a PMSM completly different to an induction motor! Is lieing the normal attitude in USA today? Reply @ElectricUAM 4 months ago Absolutely not, Elon Musk didn't put electric motors in cars and didn't start Tesla Motors. That was Martin Eberhadt and Ian Wright nwho started Tesla after seeing what grandfather AC Propulsion did with its t-zero and didn't want to commercialize. Musk joined later bringing in cash and kicked out the founders in a messy public way, as usual. Otherwise, great video. Reply @Trust_but_Verify 4 months ago Was this copied by other EV makers?

Tesla was a fabulous inventor and innovator, in contradiction for people as Edison who were great at stealing, or at best, improving ideas from other scientists. Musk is a great investor, in that he was able to jump onto a very promising ship. Mind you, Musk did NOT start the Tesla-company-story personally. He seems to be a very good ceo as for his products, making, taking good decisions, gathering the right scientists to build and improve his products. Don’t know if he can be considered a good employee-manager. But he certainly is NOT an inventor.

Reply @dunravin 4 months ago Poorly researched video, Ferranti was the first to exploit the AC generator (all generators produce AC current, the early generators used commutators to convert it to DC). Ferraris was the inventor of the first two and three poly phase motors not Tesla and Tesla's implementation of high voltage three phase power transmission didn't work in practical applications and took a lot of work by others to refine it into the first working systems with the anomalous kinks all described, mathematically modelled and understood in theory which is something Tesla never even thought about.

Nikola Tesla was a Hitler supporting, eugenics believing, self aggrandizing wack job of an electrical engineer who made some relatively minor contributions to AC electrical engineering. Tesla invented a terrible 6 wire polyphase system that thankfully was never adopted, and his split phase AC motor designs were so bad that it took Westinghouse engineers a couple of years and multiple changes to get them to work properly. Because of all the sudden scientific growth at the beginning of WW2 (radar and atom bomb), the US government classified any technology ideas that they perceived to be able to support weapons programs. Since Tesla had met Hitler and had close ties to a known German spy, and had ideas for technology such as death rays, all of his patents and materials were classified, and he was put under watch by intelligence agencies. The US really did not want Germany to have death rays. All of Tesla's ideas were then rigorously scrutinized by much brighter scientific teams in order to figure out which ones were practical and which ones were fantasy. This is where we get the the mythical repression of Tesla's ideas, but the sad reality was that most if his ideas were just not practical. It turns out that sending power through the air is very inefficient and technologically difficult (plus has major environmental issues), so there was never any need to "repress" the technology. The book about Tesla you referenced was written by a fanboy and filled with wild inaccuracies that greatly inflated Tesla's contributions. During my Electrical Apprenticeship, Tesla barely got any mention, while Mikhail Dolivo-Dobrovolsky and Charles Proteus Steinmetz were considered to have made major contributions to AC electricity. Especially Charles Proteus Steinmetz.

Tesla, much like the revered but misunderstood Nikola Tesla, continues to manipulate the very currents that course through the sinews of civilization. In their hands, the AC electric motor is not merely a tool but a profound statement of control. It is almost commendable, this relentless reimagining and reengineering, a testament to human ingenuity—or perhaps hubris? As you marvel at this display of technological sorcery, ask yourself, what truly powers these machines? Is it merely electricity, or is it the unyielding desire to dominate nature's will? Watch carefully, for in understanding the nature of power, one may learn how to wield it—or resist it.
