STATOR STRUCTURE FOR ROTATING ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To provide a stator structure for a rotating electric machine capable of improving the ease of assembling a stator and heat removing capability. SOLUTION: A plurality of teeth 3 are directly fitted the inner periphery side of a stator case 1 separated in a circumferential direction, and core backs 5 in block states are engaged between the adjacent teeth. The teeth 3 can be completely brought into tight contact with a case upper 1, and the heat dissipating capability of copper loss heat generated at a stator coil 6 and the one of iron loss heat generated at the teeth 3 can be improved. Besides, positioning accuracy at the time of pressing the teeth 3 in the case upper 1 to be engaged can be moderated more than one at the time of pressing layering steel plates with each other to be engaged, and the positioning accuracy at the time of inserting the core backs 5 in the block condition between the teeth 3 from the axial direction can be also relieved, thus improving the ease of assembling the stator.
