PROBLEM TO BE SOLVED: To provide a means which facilitates a winding work by winding coils continuously in the same direction, in a stator where three-phase coil groups are arranged in circular form by arranging a plurality of coils constituting the coil groups of the same phase severally inclusive of positions where the phases of induced voltage are different. SOLUTION: In this stator 102, a pair of coils 21U1 and 21U4 and a pair of coils 21U2 and 21U3, in each of which the phases of induced voltage conform to each other out of a plurality of coils 21U1-21U4 constituting a group 21U of coils of U phases, are made mutually separate groups. Each coil 21U1 and 21U4 and each coil 21U2 and 21U3 in the separate groups are continuously wound, being provided with jumper wires 26U1 and 26U3 between the coils 21U1 and 21U4 and between coils 21U2 and 21U3 each in the same winding direction. The fellow separate groups are connected in parallel. Also in a V phase and a W phase, it is performed in the same way, whereby the lead wires in the three-phase coil groups 21U, 21V and 21W are star-connected. COPYRIGHT: (C)2006,JPO&NCIPI |
