The answer to this mystery is in the title of the video:
Motor de auto inducción y rotación por inercia
Translation:
Auto induction motor and rotation due to inertia.
The second part is key, the rotation is due to INERTIA. Those dremell tools can be set to various RPMs like: 15000, 7000, 5000, etc, and he just speeds up this thing very fast and the inertia of the lower wheel keeps it going. This is energy storage in a flywheel, and the energy comes from the dremell tool. The battery or capacitor at the bottom is a DIVERSION. It accomplishes nothing. The speed also decreases slowly indicative of energy depletion by friction.
Bottom line: THIS IS NOT A MOTOR JUST A FLYWHEEL AND GENERATING COILS.
EM
PS, There is another possibility for the bottom battery, it might not be a useless diversion. It is used to energize the coils and create a magnetic field so the rotor can change the inductance. Which means the rotor is not really a magnet but an iron bar, else you wouldn't need a battery at all. Looking at the rotor, it is probably pulled from an AC motor that depended on rotating magnetic fields, and has no magnets on it just steel laminations. So this explains why you need to have the coil energized first, else the flywheel can't output it's energy since there are no magnetic fields to work with.
