Abstract:
A motor/generator comprising:a first rotor having a plurality of protruding poles made of a magnetic material not magnetized; a second rotor having a plurality of poles; a stator facing the first rotor and the second rotor, the stator being provided with a plurality of coils; an inverter supplying an alternating current to the coils in response to a signal; and a microprocessor programmed to: calculate a first alternating current with which the coils generate a rotating magnetic field rotating in synchronism with the first rotor; calculate a second alternating current with which the coils generate a rotating magnetic field rotating in synchronism with the second rotor; calculate a composite current comprising the first alternating current and the second alternating current; and output a signal corresponding to the composite current to the inverter.
