ABSTRACT:
An electric drive apparatus has an electric motor having a rotor and a stator; and a magnetic pole position detecting portion having a sensor rotor attached to the rotor, and a sensor stator that is adjacent to the stator, and that is fixed to a case, and that extends over a partial region of the sensor rotor extending in a circumferential direction. Because the sensor rotor of the magnetic pole position detecting portion is attached to the rotor and the sensor stator is adjacent to the stator and is fixed to the case, it is no longer necessary to use an all-round embracing type magnetic pole position detecting portion that embraces the entire shaft of an electric machine.
