Video: Understanding the Tesla Model S performance motor

Join John D. Kelly of WeberAuto for a deep dive into the details of the 18,000 rpm performance rear motor and drive unit from a 2015-2016 Tesla Model S P90D. This drive unit is similar to the one used in the 2017-2020 P100D. The video is divided into four sections showing:

1. The motor and gears

2. The high-performance bearings

3. The lubrication system

4. The cooling system.

CORRECTIONS:

The Nissan Leaf ring gear is held on with eight bolts, not six; the fluid in this drive unit is Dexron-VI transmission fluid; induction motor rotors do not have poles, just the stator. The 60 slot stator has four poles; and silicon nitride is a ceramic material.
