Tesla Model 3 and Y Modular Motors

Check out the modular components and design of the electric motors on the Tesla Models 3 and Y. See how many parts are common and interchangeable. Corrections: 1. I swapped the definition of a Hunting gear set with a NonHunting gear set. TIMELINE: 0:00 Introduction 0:27 The rear motor of the Model 3 and Y 1:08 The input shaft with 31 teeth (Prime Number) 2:00 the input shaft SKF bearings for a rotor speed of 18, 447 at 262 km, h (163 mph) 2:40 The countershaft and gear with 81 teeth (Factors 3, 3, 3, 3) 3:00 The input shaft to the countershaft gear ratio of 81, 31 2. 6129:1 3:10 The countershaft pinion gear with 24 teeth (Factors 2, 2, 2, 3) 3:15 The ring gear and differential case with 83 teeth (Prime Number) 4:30 The countershaft to ring gear ratio of 83, 24 3. 4583:1 4:43 The overall gear ratio (81, 31) x (83, 24) 9. 0363:1 5:03 The published gear ratio is incorrect. This is a Hunting Gearset 5:48 The CV halfshafts connect to the differential side gears 6:46 MUST SEE: two cool Permanent Magnet rotor de
