<P>PROBLEM TO BE SOLVED: To provide a stator for a 3-phase rotary electric machine for which a crossover is insulated by a simple method for the stator in a spirally wound state composed by repeatedly arranging coils of respective phases in the same array order, and its manufacturing method. <P>SOLUTION: The stator 1 for the 3-phase rotary electric machine is composed by arranging the coils 3U, 3V and 3W of three phases that are a U phase, a V phase and a W phase to a plurality of slots 21 provided on a stator core 2. The 3-phase coils 3U, 3V and 3W are inclined relative to a circumferential direction C and repeatedly arranged in the same array order by being formed from the state of being biased to an end part on a radial direction outer peripheral side on one side in a circumferential direction to the state of being biased to an end part on a radial direction inner peripheral side on the other side in the circumferential direction at a coil end part 30. At the coil end part 30, a plurality of crossovers 4 connecting the coils 3 of the same phase with each other are arranged over the coils 3 of the other two phases. An insulation tube 5 having insulation quality is equipped externally on the crossovers 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
