As an electronics engineer, that was the most amazing circuit board I’ve ever seen. Everything from microwatt to kilowatt components sharing the same PCB. Incredible.

The kid's going places. He's done a great job with the teardown and presented a very succinct explanation of the drivetrain components.

Please, please, buy a couple of body mics. The content is great, but the variable audio needs work. :)

This is the most ethical tear down

That was really neat, straight to the point not crap talk , just what the title said , subbed for more

Absolutely nuts that a motor that small can fling a 4000 pound car full of people back into their seats. I freaking love electric vehicles.

I have Been working in the EV industry for quite some time and have seen so many trainings/teardowns. But this is one of the best. No jibber jabber straight to the point. This is exactly what will attract young engineers

The future of car mechanics!!! Everything looks simple and clean not full of dirt and grease with a thousand parts.

the young man did a nice job explaining every thing

This is an excellent video, everyone else like “What’s inside” doesn’t go this in depth. New subscriber!

Great disassambly. This is a marvelous piece of engineering and a slap on their faces who says EVs just have a motor and a battery and nothing like gasoline engine.

Whoever made this motor and these parts did it beautifully and seemed to get a lot of joy designing it. At least, that’s what it transmits to me.

as a time served mechanic I must say this is a very smart simple system I'm impressed

Best Tesla rear electric motor explanation out there. Pure education about this outstanding piece of engineering. A must-watch. Keep it up All EV Canada!

give that young man a raise

Straight into business with no bs. An absolute gem of a tutorial really. Thanks!

That "speed sensor" looks like a "resolver", as it's called. A resolver is a miniature motor that doesn't actually produce motion itself, but induces signal between the phases that the controller can read the exact, precise position of the motor at incredibly high speeds with. In order to drive a brushless motor like this, the controller (please don't say inverter ;) it does much more than that!) needs to know exactly what position the motor is at. That's the job of the resolver!

I've been learning about internal combustion engines/transmissions for years now and it's difficult to find channels teaching about the inner workings of an electric motor. Glad you guys are here to teach us

Nice breakdown of the motor, drive gears, cooling system for the motor and electronics. Glad to see young people taking an interest in and learning how all this works.

Thank you for sharing! It's Awesome with an 'A' that we can see the insides of something so innovative. I give so much props to the engineers that created this amazing machine. and to EV Canada that specializes in them.

Great video, I learned a a lot and I appreciate you getting straight into the video without a 2min intro! I work on gas cars at the moment, but I'm interested in learning about EVs as well. Subbed and liked keep up the great work!

Let’s see, so I can go with an inverter, rotor, stator, fixed ratio gear reduction, a splash of oil and coolant, and make tons of power OR, go with an engine block, head, crank, cylinders, rings, con rods, wrist pins, valves, spark plugs, turbine, fuel injectors, fuel pump, water pump, all the associated piping, a starter motor, drive shaft, multi speed transmission, radiator, exhaust manifold, catalytic converter, resonator, muffler, plus gallons of oil and coolant with some seals and gaskets that will hopefully keep it all in, just to produce an inferior power to weight ratio in a less efficient manner… I know what the better option is, and I voted with my wallet.

Excellent job describing the teardown...cool to see the details inside the drive unit!

Dude.. thats some serious built quality....

So cool! Brilliant breakdown and explanation.

This is extraordinarily good video; all that’s missing is what spec. Of oil goes in it! Speaking as a Mazda mechanic 1991-2000 & an IT guy since, this made me very happy.

Mitch was awesome! Easy, fast, engaged, perfect!

You did a great job showing and explaining what each parts are and what they do.

I am currently studying Electrical Engineering and absolutely enjoyed this video! Subscribing!

The rear motor on a model 3 is 220 hp, it's amazing to think that small rotor/stator assembly can produce so much power output.

A grand thank you to ALL EV, for sharing your expertise, and information

By far the best 'how Teslas work' video I've seen (apart from the audio!). But I wish you'd spent a few minutes on how the motor works - solid magnets produce good torque but the reverse induction causes problems at high speed - that sort of thing. The design of these units is very clever (although I would have gone for a more modular approach for ease of service/repair), but the genius is what goes on inside the actual motor and how Tesla have got round the induced emf problems, etc.

Most modern cars have open differentials now, and use the abs control to apply the brakes to spinning wheels. I expect that’s how the Tesla works.

Very interesting. I have seen a teardown of a motor from I think a P100D and I don't think it had an oil filter or an oil pump. Very impressed with the solid cases and gears. Definitely built for a long life. I wonder what the change interval of the oil and filter is? Thanks for taking the time to do the hard work for us sticky beaks

Excellent presentation of a 21st century mechanical wonder, thanks, I really enjoyed the video!

Great video and I love the simplicity in which the motor and inverter assembly was explained.

Good work we want lot of videos like that

_Mitch Gregory looks like a young Chip Foose._

Excellent teardown & explanation! Thanks for sharing!

Such a great video. You guys did a great job explaining everything!

Interesting. Could do without the techno background music.

Thank you for the great video. I always appreciate and admire the genius inventor of the Three-Phase Induction Motor, Nikola Tesla. The idea of a rotating magnetic field that is produced by a three-phase supply to the stator is crazy. Plus, to vary the speed of the rotor, just vary the frequency through a VFD circuitry.

It was worth watching, every minute of it, thanks

Wow how elegant, clean and modern in contrast to an internal combustion engine. Show us once again that this is the future!

Great video! Very inspiring for DIY peolple, like me !

Great job! You guys are so professional! The Tesla e-drive system is a piece of art. I'm a power electronics and motor control enginner and already got quite familiar with the inverter part. What I'm curious about is how the oil cooling of motor works. Looks like it shares the same oil of the gearbox but I'm not sure the path of oil flowing through the motor.

Best video of its kind I've seen. Well done guys and thanks for your effort.

Respect from Baku,Azerbaijan

Respect ! :)

Dan from What's Inside watching this video and wondering 'dang! We should have hook with that kid when we tore down our Tesla Motor'

Forget Tesla, the smile of this girl is a piece of an endless happiness. 6:45.

I cant thank you enough you just made my seminar much more informative thank you 😊😊😊

Hi, what was the manufacturing date of this Model 3?

Please take apart the stator and the rotor magnets and show us the arrangements. I believe the stator is pretty typical but the magnet arrangement is a bit special.

Really great content, thanks for showing us the insides of the vehicle. Hope to see more

Wow I admire the young buck and his knowledge concerning this type of technology within the tesla electric motor. Well done young man.

Thanks for super content - Please consider if the music is needed. Personally I think it is disturbing

So interesting, never seen the guts of an EV before! But your sound could use some work, guys.

Thank you for not wasting my time with filler content and goes straight to that sweet sweet forbidden knowledge

Havent really seen a motor break down like this yet, great job guys keep it coming.

Very cool to watch. I used to work for a PC power supply mfr, and remember that higher frequency reduces component sizes (which is why aircraft run on 400Hz). Any idea what frequency the AC is?

loved it ! Can we have a video of putting back all together and starting it?

Nice job of disassembly and explanation of each step! 👏👏👏

EV are so simple than i thought thanks for sharing 😊

In less than 20 years combustion engines will be approaching historical curiosity status. The electric drivetrain is so vastly superior in every meaningful way.

The simplicity and high performance of this compact power unit (engine, 'gearbox', differential) is the k.o. for combustion engines. Moreover, when you consider the savings in maintenance.

Impressive explanation of how everything works.

Those motor Are Gold! The battery are diamond!

looks like Elon had a lot of sleepless nights at the factory.

cool interesting video, I hope you make more of these video. Minor feedback to step up your game on the video making : -renting or buying lavalier(lapel) microphone would allow a to capture only the voice and not echo and background noise, they are not very expensive -another option for the audion is to use a more directional mic instead of a omnidirectional mic. this would only record audio where you point it -as other have mentioned the music was distracting and doesn't really add value to the final product, this is a niche video for people who are really interested in learning, a bit of silence isn't what will scare off the people who would watch this type of video. As I said these are minor things you will get better with each iteration, we cant be expert in every field, but sharing our knowledge with each other helps us get closer.

Nice crisp explanation, Thank you Mitch

These guys are good! I loved watching that. So demystifying

So does that mean to make the motor last there should be oil change maintenance? There should have been oil pan with drain plug for DIY at home.

I like it Without music

Awesome video. Very detailed. I love doing videos on smaller things, I can't get my hands on these yet. Thanks!

Great explanation, clear dismantling. Good job.

wow, thank you. i just finished watching a couple goofs tear a model s motor apart and man i learned absolutely nothing. this made up for all that!

Elisabeth's jeans are amazing!

the no noise version is excellent. thank you for doing this video. I come for information, not music. without the music the mics are not that bad.

Very good demonstration and explanation. Thank you!

"Laid oot nicely" 9:51

Please have Elizabeth do the next teardown

A good, clear and informative presentation. Thank you.

Excellent video, I enjoyed every single minute. Hope you keep posting

Wish you'd torn down the actual motor part more, id like to see the insides of the rotor

Every hundred years come to this world a person who change drastically our way of life for better. Now we have with us Elon Musk.

Brilliant insight an teardown into this car. Welldone again.

Really comprehensive and complete explanation, I learned a lot!

You want to find somebody who looks at you the way I look at that rotor.

It's really that simple!?!? Amazing, I'm guessing in a couple of years EV's will be half the price of combustion engine cars.

Excellent & cool video,simple & easy to understand!GREAT job!!

Amazing!! So cool to see and also explained.

This video is missing three things... smoke machine, lasers and podium dancers. Please round out the next video by filming inside of a nightclub. Great content.

And I thought I would be through with oil changes on my Tesla.

incredible job guys, enjoyable watching this video

Beautifully explained and this will give a better insight for those who want to explore in EV

Is there a schedule for changing oil and filter like an ICE?

Dam that rotor and stator are so small, how does it have so much power to move a vehicle so fast?

Very well explained, you are at the start of a exciting career young fella !

Awesome job guys.. Just bought a model 3 so this was very interesting!
