摘要： A multiplex multiphase winding AC motor includes an armature iron core provided with a plurality of teeth and a plurality of slots, an armature winding provided with two or more groups of multiphase windings that are wound around the teeth and are contained in the slots, a plurality of motor driving apparatuses independently connected with the two or more groups of multiphase windings, and a magnetic-field-pole iron core provided with a plurality of magnetic-field poles arranged in such a way as to face the armature iron core through a gap; in the magnetic-field-pole iron core, a plurality of magnetic resistance elements for impeding a magnetic-flux flow in the circumferential direction thereof are formed.
