Title:
ROTATING ELECTRIC MACHINE AND ROTATING ELECTRIC MACHINE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/203849
Kind Code:
A1
Abstract:
An M-phase rotating electric machine (10) is formed by housing a rotor (14) and a stator (15) in a case (11), said stator being formed by winding a coil around each of a plurality of teeth (25) disposed in a radial fashion. In the rotating electric machine, the stator has a plurality of small cores (24A) each equipped with a predetermined number of teeth and a core back (26) for coupling the base portions of these teeth and disposed in a circumferential direction at constant angle intervals and is provided with gap regions (27) between adjacent small cores. The small cores are integrated by a ring-shaped insulating member (28) that couples the coil bobbin portions (29) of the teeth through a connection portion (30). Alternatively, the small cores are integrated in such a way that the insulating member is provided that couples the coil bobbin portions of the teeth through the connection portion, the coil is wound around each of the teeth, and then the core back is fixed to the case by a fixing means (33, 34, 35).
