Model Y E22: Changes inside the Model Y Front EDM and Comparison to M3

Episode 22: Sandy walks us through the similarities and differences observed in comparing the front EDMs (Electric Drive Module) and induction motors on the Model Y and Model 3. Additionally, we review some of the basic functionality of an EV's gearbox and drivetrain.

Another weekday morning, another Sandy talking above my simple head about a Model Y piece. You're making this lockdown that much more bearable, thank you!

5:50 - _"I just don't known how they developing the power that they are..."_ - Sandy

It’s interesting how they have changed the motor in the Y. I wonder if the current build 3s are using the same new design.

[NinetyTres]

It is like watching a tear down of brushless RC car motors in full 1:1 scale
They look very similar
The deeper the dive on this MY, the more interesting it is
Thank you for all you do Sandy

[cristi_ei]

It may be that the current Model 3 being produced now uses the same design as the Y since you looked at an early build Model 3. It's known that Tesla does small incremental updates all year round to thier products.

[tomokatsuDesign]

Surprised to see such a significant difference between the 3 and Y rotors. Don't believe Tesla had announced anything about having different drive systems - I'd always assumed they'd be part of the shared components. Can't wait to see what's inside.

[Jimmy_Jones]

It's been revealed. Spiderman is the Tesla motor secret sauce.

[Drunknmunky]

No doubt the new rotor is being used in the Model 3 as well

[DouglasEKnappMSAOM]

Loving your show. I would love to hear a bit more detail and also depth but with an eye on the fact that I a programmer not an engineer. I am sure many here fall into this group of great intrest but little learning.

[Cryogenic]

For a "new" company in the car industry (well at least compared to the hundred-year-old mammoths) Tesla sure has lots of secret sauces in their vehicles.

[HotBazzinga]

Spiderman is where I want to be, right in the middle of this level of engineering nerding out.
Fantastic work guys, can't wait to see the inside of the motor parts!
I'm wondering if some of these new motor designs have made there way into some of the other cars already.

Please go over if the coolant flows between the stator and rotor for co axial cooling of the electric motor.

[liamkelly]

I like the new intro Mr. Munro. Very nice touch.

[Buzzhumma]

Well they can do amazing things with signals these days so the high rpm can be reached and also with liquid cooling they can seriously overdrive the stators coils and feild weakening can be acheived at higher rpm with possible delta-star switching . It would be great if sandy could acquire the signal waveform data going to the motor. It would be sinusoidal but i feel it would change shape in the waveform at different loads and rpm .Can you get that readout Sandy ?

[kevinparker]

It would be nice if @Munro did a video on the shielding materials and composition of the casing around these very power electric propulsion systems.

[alfredogonzalez]

Can't get enough of these episodes. I wish they were 30 or 40 minutes long to learn more about all these automotive details.

[PhillProbst]

So, I gather that there is no reverse "gear" per se, but rather, reverse is accomplished by running the motor backwards?

[rajanvr]

Thank you dear sandy, booked my model Y

[usamericans]

Hey Sandy, is it OK to change gear in motion in Teslas? The car lets you shift gear under 5 MPH, which is really useful. I don't want to break anything though. Thanks for another great video!

[melvis]

Great videos Sandy. I've been following your advice and tipping my cashiers.
