Abstract:
A motor/generator comprising:a first rotation shaft; a first rotor rotating with the first rotation shaft and having a first number of magnetic poles that form a first magnetic field; a second rotation shaft rotating relative to the first rotation shaft and supported co-axially with the first rotation shaft; a second rotor rotating with the second rotation shaft and having a second number of magnetic poles that form a second magnetic field, the first number and the second number being different, the first rotor and the second rotor being disposed in series along the first rotation shaft; a stator provided with coils each of which generates a first rotating magnetic field in synchronism with the first magnetic field by application of a first alternating current, and generates a second rotating magnetic field in synchronism with the second magnetic field by application of a second alternating current; and a current control device that supplies a composite current comprising the first alternating current and the second alternating current to each of the coils.
