摘要：PROBLEM TO BE SOLVED: To increase torque to be generated by preventing an amount of magnetic flux formed in teeth from being suppressed. SOLUTION: A stator structure 1 is equipped with a plurality of teeth 2 adjacent to each other in the circumferential direction and a core back portion 20 for connecting the teeth 2 in the circumferential direction. The stator structure is also equipped with a stator core 3 equipped with a plurality of segments 5 arranged in the circumferential direction and inter-segment core back portions 6 for connecting the adjacent segments 5 in the circumferential direction, and a coil 4 wound around the teeth 2 of the stator core 3. The inter-segment core back portions 6 have a cross-sectional area smaller than that of the core back portions 20. COPYRIGHT: (C)2009,JPO&INPIT
