Tesla's Newest Motor & Drive Unit

Here we teardown Tesla's newest Motor and Inverter tech!

The Tesla part number for this Drive unit is 1665000, so I'm calling it the "Triple 0". Tesla also has a 3 letter designation of 4D1.

Weight (wet): 194 lbs/88 kg

If you would like to support me directly:

Haripin stator appears to have 54 slots with 8 bars in each. Stator resistance is 8.1 milliohms, vs 10.4 milliohms for the Gen 3. (taken with 4-wire kelvin connections on my 6.5 digit Keysight 34461A using a 10 second sample time)

Parts on PCB:
Safety Controller: 16324 1TC TC14427 2212 (assumed Tesla proprietary)
IR Temperature Sensors: ACC T5977510 (Could not locate)
Pyro bypass fuse: Buss TS-10A05F T10AH500V

PCB size: 11.5" x 7" (292mm x 178mm)

Have a coffee on me! Wonderful to see the evolution of these boards... they're whittling away at things nicely and suits the cliche "The best part is NO part." mantra.

Seems like you are the first to get these motors and drive units. You were the first that I saw with the Model S Plaid motor teardown and now you are the first with the new Tesla motor and drive unit. Thanks for doing this and to the folks that help you source them.

This is the most underrated channel showcasing Tesla parts.

[SuperfastMatt]

Excellent video. Always nice to see your teardowns.

I used to be engineer with a company that produced fork truck DC controllers (largest I had worked on was a 60V 900A) and later mobile wheelchair and scooter controllers. Super impressed with how compact and simple this design is! I know to make things simpler and cheaper its a lot of work (same goes for software - more effort to reduce code complexity).

A lot better than Munro teardowns, he would complain about the number of threaded fasteners.

[cuulmaenleu]

Wonderfully detailed. Next to Munroe Live one of the best technology-focused Tesla channels!

[akmanarda]

Still the best technical tesla content there is. 👏👏👏

[garthberry]

Great teardown, the embedded transformers for the gate drivers are brilliant!

It’s impressive that you know all that and you don’t work for Tesla. It really shows your knowledge.

[jwp]

Good to see you are continuing with posting excellent content. Your circuit board component descriptions are very interesting to me.

[dannyames]

Wow, so cool to see this new stuff ^ Thank You Phil. BTW Your welcome to my Cybertruck if you still don't have one by the time my reservation delivers. For a one man band you do great work.

[adamshawley]

YAY! You're back. Awesome content as always. Really appreciate your stuff. Thanks for another excellent teardown.

The thing with infrared sensors for FETs (IGBTs?) temperature monitoring has blown my mind! Seems like an ingenious solution, where you don't have to rely on physical contact, clearances and thermal compounds to relatively accurately measure the temperature.

[cwcordes]

WOW Thank you so much, I saw the hair pin stator with the rectangular wires and my jaw dropped.
The fact you knew you had to design fixtures to prevent a rotor magnetic crash during disassembly really impressed me.
Tesla is years ahead.. I really enjoy your teardowns.

[TeslaRebuilders]

This is really good as I bet @MunroLive would like to see it!

[rogerstarkey]

What (still) impresses me is that this basic motor concept drives all vehicles from Model 3 to the Semi (we can no doubt add the new models as they arrive)
It's essentially just a question of changing the gearing (and decoupling on the Semi ... Maybe the CT🤔?), then altering the power application map to suit the vehicle.
"Genius".

[petersadow]

Great video. Very informative and well presented.

[erik]

Very nice presentation. Just subscribed. NOT too technical. Did I miss weight of new unit vs old?
