PROBLEM TO BE SOLVED: To provide a stator structure for a dynamo-electric machine capable of reducing a cogging torque generated between a stator, and an outer rotor or an inner rotor. SOLUTION: This stator structure for a rotary electric machine comprises; a stator 101 radially arranged with a plurality of laminated cores formed by winding a coil 101A around a plurality of stator teeth 101B composed of laminated electromagnetic steel plate 201; an outer rotor 103 provided on the outside of the stator; and an inner rotor 102 provided on the inside of the stator. The stator teeth 101B are divided into (n) sections in the layering direction. Each of the divided stator teeth has a different magnetic flux direction. COPYRIGHT: (C)2006,JPO&NCIPI
