Abstract:
To provide a rotary electric machine in which mutual interference between armature coils hardly occurs and an axial height of a coil end portion is reduced.SOLUTION: In an armature coil 8, a slot storage part 81 disposed inside of a slot 71 of a stator core 7 comprises an inner diameter side slot storage part 81a and an outer diameter side slot storage part 81b which are respectively positioned at an inner diameter side and an outer diameter side of the slot 71. A coil end portion 82 drawn to the outside of the slot 71 consists of: an inner diameter side coil end portion 82a which is bent from the inner diameter side slot storage part 81a; and an outer diameter side coil end portion 82b which is bent from the outer diameter side slot storage part 81b. An angle θ1 formed by the inner diameter side slot storage part 81a and the inner diameter side coil end portion 82a is set larger than an angle θ2 formed by the outer diameter side slot storage part 81b and the outer diameter side coil end portion 82b.SELECTED DRAWING: Figure 9
