Understanding the Tesla Model S Performance Motor

Join me 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. and 4. The cooling system. CORRECTIONS: Thank you to everyone for catching my errors. There are always errors ;) 1. The Nissan Leaf ring gear is held on with 8 bolts, not 6. 2. The fluid in this drive unit is Dexron 6 transmission fluid. 3. Induction motor rotors do not have poles, just the stator. The 60 slot stator has four poles. 4. Silicon Nitride is a ceramic material.
