TIMELINE:
0:00 Introduction
0:27 The rear motor of the Model 3 and Y
1:08 The input shaft with 31 teeth
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
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
3:15 The ring gear and differential case with 83 teeth
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
5:48 The CV half-shafts connect to the differential side gears
6:46 MUST SEE: two cool Permanent Magnet rotor demonstrations
8:05 The modular design of the motor shafts and rotors
8:25 MUST SEE: Watch as a rear motor is changed into a front motor
10:32 The differences in the modular motors
11:35 See what a permanent magnet does to the Induction Rotor
11:55 An aluminum core front induction rotor on the Model Y
12:13 There are at least three different rotors for the Models 3 and Y
13:54 See the rear motor inverter and where it attaches to the rear housing
14:45 The matching part numbers of the rear inverter and the stator (A matched set)
15:15 The three different power and torque levels of the Model 3 and Model Y
16:15 MUST SEE: See the front motor inverter attached to the rear housing!
17:37 the common bolt pattern and opening for the stator housings
18:30 The oil-cooled stator and ATF-9 fluid
18:47 The interchangeable transmission heat exchanger
19:13 The interchangeable variable speed electric oil pump
20:25 The interchangeable spin-on oil filter
21:06 What is not interchangeable between models
21:20 The rear drive-unit is mounted parallel with the ground
22:20 The front drive-unit is mounted upside down and on an angle
23:05 The matching part numbers of the front inverter and the stator (A matched set)
26:30 Additional EV training opportunities at https://www.weber.edu/evtraining
26:58 Video summary and donation opportunity

The devil is usually in details. Here we have whole devil's wedding party in one assembly.
The induction motor and synchronous motor principles are not changed from 19th century, but the way Tesla makes it running for us makes me very confident in my future Cybertruck.
