High efficiency DC motor with generator and flywheel characteristics

摘要

A high efficiency multi-phasic type DC motor incorporating brushless electronic switching to phase the attractive and repulsive forces between the permanent magnets in the rotor and wire wound air core coils in the stator. The unequal number of magnets and coils provides a designed imbalance, so that proper energization induces rotation and torque in the motor's dual flywheel rotor. Electronic switching collects inductive kickback and back emf simultaneously during the motor phase and in addition, disconnects the attraction and repulsion phases during regenerative braking, etc. and directs all this generated power back to the power pack where it is stored in batteries and capacitors. The rechargeable batteries and capacitors in the power pack are the source of operating electrical power for the motor. The rotating assembly is designed to have adequate mass so that the kinetic energy of rotation smooths out the pulsing moments introduced by the attraction and repulsion of the coils and magnets and to ensure continuous rotation of the dual flywheel rotor. The combination of electronic switching, the low hysteresis loss in the air core coils, the streamlined configuration of the rotor which reduces windage loss and the recovery of the generated currents in the air core coils contribute to the high efficiency of the electric DC motor.
