Abstract
A rotational difference is generated between a first and a second rotor and a third rotor, which causes an induced current to flow in a first rotor winding. This causes a torque to act between the first rotor and the third rotor. The rotary magnetic field generated by the induced current flowing through a second rotor winding interacts with a second stator, which in turn generates an induced electromotive force in a second stator winding. The induced electromotive force is applied via a phase adjustment circuit to a first stator winding, which generates a rotary magnetic field and causes a torque to act between the first stator and the third rotor. The rotary magnetic field generated by the second rotor winding and the induced current flowing in the second stator winding causes a torque to act between the second stator and the second rotor.
