bike motor controller torque performance in speed and excellent performance is due to change by the coil – in order to prove the authenticity of my first published the theory – by reversing the coil is hub motor controller, by reversing the phase AC motor. By changing the coil to the premise of achieving the rotating magnetic field in the rotating among each of the stator magnetic pole corresponding to the current conductor always flow in one direction. “Replaced with the current tracker commutator and brush,” the conductor of the stator current direction is always tracking the rotor poles, can achieve zero speed to rated speed constant torque swing speed, and there is no torque ripple, inverter can be completely eliminated governor, governor of the chopper transformer will be popular in the world.

Installed on the synchronous motor synchronous brushless commutator can not be called bike motor controller, the scientific community of distorting the facts, because it is the by-phase commutation – is the AC motor, it can never find hub motor driver torque performance and speed performance.

Rotating magnetic field hub motor driver, with the durability of induction motor and rotating armature hub motor driver torque performance in speed performance, is the most perfect performance of the motor, speed control will not produce direct current transformer harmonic pollution in power, speed cost is very low. It can be raw materials for manufacturing into a more limited market value of commodities, will become the goose that lays the golden eggs, the entire motor industry will lead to a revolution, the rotating magnetic field hub motor driver to the power of today’s IGBT IEGT capacity, single power to do 50000KW is easy. Engaged in electrical research staff to look at my town scientific and technological achievements, we know that all this is true.
