Multiphase electric motor - 100 % efficiency
Alex AC
The principle of the resonant motor is based on the resonant frequency of the motor coil. This coil must also have a separate core, because in the case of multi-phase motors, the magnetic fluxes in the core are "beating".

Basically it's like a swing. If we rock a child, we use the resonance frequency of the swing, and at the end of one swing we just fill the drop of the swing, caused by friction and air resistance. That means we just push a swing on one side and it will come back to us. Our multi-phase motors work differently. We have invented 50 or 60 Hertz's in the network, and we feed motor coils regardless of their resonant frequency. It's like we swing to swing our frequency. For example, we would set 5 seconds down and 5 seconds back. We had to keep our troop first by way of the bottom and then push the other side in 5 seconds and another 5 seconds to go the same way back. It would be difficult and would not last for long. But we do it for motors, and we do not care what resonant frequency the motor coil has with the capacity, between the threads and the power cables. We press 50 or 60 Hertz and the motor must work. And what difference in energy consumption does it make? Well, practically this can be found in the swing. In the classical way, we can swing the baby one hour, but in the frequency determined by us, it will be a short time. If we add a three-phase motor construction to this, there's the "energy jar" we use today.

If the rotor is mounted with magnets, we get a very powerful generator.
