no serious explanation of watt makes the actual motor run,

The model S uses 3 phase AC induction motors, which as you probably know, consists of little more than a rotor and a stator full of windings.
At about the 4:20 mark, you can see them remove the end cover of the actual motor and spin the rotor around within the stator. Then they tear into the opposite end, which houses the inverter (the electronics necessary to convert DC into 3 phase AC current), and finally they open up the gearbox which is sandwiched between the motor and inverter.
After they got the gearbox opened (pause it at 10:14), it appears they could have just removed those 3 bearing retainer screws and slid the rotor out of the stator...But they didn't go that far.
