An AC electric motor includes an annular A-phase winding WA wound in the circumferential direction of a stator, a stator pole group SPGA configured to generate magnetic flux &phgr;A to interlink with the A-phase winding WA, an annular B-phase winding WB wound in the circumferential direction, and a stator pole group SPGB configured to generate magnetic flux &phgr;B to interlink with the B-phase winding WB. The motor additionally includes a third stator pole group SPGC, N and S magnetic poles of the rotor, and X magnetic poles, which serve as third rotor poles, showing magnetic characteristics between the N and S magnetic poles of the rotor. DC currents are supplied to the A-phase and B-phase windings WA and WB to generate rotational torque.
