The current from the external source of energy consumption is very low.
You can land even half way according to the type of engine.
Here, in addition to fiction are used in the stator that allows the rotation of a simple mechanical.
A simple change in the mechanical design of electric motors at very high speeds, even with both the coaxial rotor and stator, synchronous and can return in the opposite direction.
The coil structure is changed in the case where a rotor stator rotor turning angle when it is returned and a full dinamiksel out much torque.
Experiencing two times with each other in a round coils, the number of the motor speed twice the torque.
This diameter and half the weight of the motor reduces.
