Abstract

A resonant motor system having a resonant circuit that includes magnetic coils and of capacitors, for generating an electric power when the resonant lot is rotated by an engine, a regenerating portion for the resonant motor, a motor driving portion, a motor control portion, and a capacitor portion for storing therein the electric power generated by the resonant motor when the resonant motor is regenerated, the resonant rotor being driven by the electric power stored in the capacitor portion when the engine is assisted by the resonant motor.
