ROTATING ELECTRIC MACHINE FOR INTERNAL COMBUSTION ENGINE AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2015/174091

A1

A stator coil (33) of a rotating electric machine for an internal combustion engine is equipped with a multi-phase winding group having phase coils (u1, v1, w1) and another multi-phase winding group having phase coils (u2, v2, w2). In a winding process, inter-phase jumper wires (PJ1a, PJ1b, PJ2a, PJ2b) and an inter-group jumper wire (GJ) are formed. In the winding process, all lead wires are disposed at one end of a stator core (32). In the winding process, a jumper wire (SJ1) is disposed on a half portion of the stator core (32), and another jumper wire (SJ2) is disposed on the remaining half portion of the opposite surface of the stator core (32). The winding direction of one phase coil of one multi-phase winding group is opposite to the winding direction of another two phase coils. This configuration provides lead wires separated by one or two magnetic poles (32a). It is possible to continuously wind a plurality of phase coils and form a lead wire from a short jumper wire between the phase coils.
