POWER TRANSMISSION DEVICE

摘要

A rotation difference is generated between a first and a second rotor (28, 78) and a third rotor (18), which causes an induced current to flow in a first rotor winding (30). This causes a torque functioning between the first rotor (28) and the third rotor (18). The rotary magnetic field generated by the induction current flowing in a second rotor winding (80) functions on a second stator (66), which in turn generates an induced electromotive force in a second stator winding (70). The induced electromotive force is supplied via a phase adjustment circuit (43) to a first stator winding (20), which generates a rotary magnetic field and causes torque functioning between the first stator (16) and the third rotor (18). The rotary magnetic field generated by the second rotor winding (80) and the induced current flowing in the second stator winding (70) cause a torque functioning between the second stator (66) and the second rotor (78).
