Abstract

A rotary electric machine for a hybrid vehicle includes a rotor connected between a vehicle engine and a torque transmission mechanism at the back of the vehicle engine and a stator. The rotor includes an outer rotor portion having an inner surface electro-magnetically connected to the outer surface of the stator, an inner rotor portion having an outer surface electro-magnetically connected to the inner surface of the stator. The stator includes a stator core disposed between the inner rotor portion and the outer rotor portion and a multi-phase winding wound on the stator to be electro-magnetically connected with both the outer and inner rotor portions.
