Asynchronous motors are equipped with a rotor coil on the rotor. Due to the slip between the stator and the rotor, the rotor coil generates an induced electromotive force and forms the magnetic field magnetomotive force of the rotor. The magnetic field magnetomotive force of the rotor generates a magnetic braking torque on the magnetic material stator. Synchronous AC motors, synchronous alternators, and DC brushless motors are equipped with permanent magnet materials or electric excitation coils on the rotor to establish magnetic poles and form a constant magnetic field. The constant magnetic field formed by the rotor generates a magnetic system for the stator of magnetic material. Dynamic torque. Because the magnetic braking torque generated by the above motors must be overcome, the motors increase energy consumption and reduce output power. Summary of the Invention

The stator and stator yoke are made of non-magnetic material. The dual rotors of the present invention form the same magnetic field under the action of a magnetic field, and the dual rotors of the split-shaft device operate synchronously under the restraint of the same magnetic field.

The rotating magnetic field generated by the motor stator coil directly drives the rotor magnetic field, which in turn drives the dual rotor to run with the rotating magnetic field generated by the stator coil. The constant magnetic field generated between the magnetic poles of the dual rotor on the generator is directly driven by external power. Rotate and cut the stator coils to generate electricity.
