Abstract:
A motor-generator device comprising:a combination motor-generator, said motor-generator becoming a generator for generating D.C. current in a pair of terminals thereof in one current flow direction when a rotary shaft thereof is rotated in one rotational direction by an external force and becoming a motor for rotating said rotary shaft in the same one rotational direction when D.C. current is supplied to the pair of said terminals in a current flow direction opposite to the current flow direction of the D.C. current generated by said generator direction;an electric double layer capacitor for storing the D.C. current generated by said motor-generator operating as a generator and supplying the D.C. current to said D.C. motor-generator when said D.C. motor-generator is operating as a motor,the pair of said terminals of said motor-generator and terminals of said electric double layer capacitor being fixedly connected directly by a pair of conductors; and,mechanical means acting on said rotary shaft for permitting said rotary shaft to rotate only in said one rotational direction.
