how does this transmission work???

I had seen this video:

Can someone give me the circuit diagram of this?

A motor and generator are the same thing. An applied voltage to a motor/generator determines how fast it wants to turn. If it is turning faster, it generates power (current), which causes a drag that tries to slow it down. If it is turning slower, it pulls power (opposite direction current) to try to make it go faster. The two wheels (motor/generators) are wired together and will want to be turning the same speed (assuming they have the same Kv). Turning either wheel by hand will generate a current that will drive the other to go the same speed.

This is easier to demonstrate with two simple DC brushed motors, because no other electronics are needed. Just wire two brushed motors together and you will see the exact same thing, where either one being turned will cause the other to turn the same (or opposite if the wires are crossed).

I understand the brushed motor case, but brushless motors have NOT 1,but THREE wires. So, what about that???

Every phase energises corresponding phase on other motor, if spined up slowly/ carefully, they stay synchronized and spin together at same erpm. If you spin it violently, other wheel can potentially not synchronize and just jump forth and back or even start to spin in other direction at unusual rpm.

There ARE three wires... three thinner white ones in the middle joining the black covered ones from each wheel that look like a single big wire. But its just the normal three in a bundle coming out of each motor.

Another question: Is the motor running on 3 phase AC? I'm asking this as I saw this video: https://m.youtube.com/watch?v=7hfClQh3rxM and in this video the person says that it generates 3 phase AC. Also, if the motor runs on 3 phase AC, then can an rc motor run on that?
