Rotary electric machine
First Claim
1. A rotary electric machine, comprising:
- a rotor;
a stator core disposed to oppose the rotor, wherein the stator core is formed with a plurality of slots extending in an axial direction, and each of the slots is defined with a first wall and a second wall that oppose each other in a circumferential direction; and
a stator winding wound around the stator core, wherein the stator winding is a continuous winding, wherein the stator winding includes insertion portions held in the slots, wherein each of the insertion portions has a cirumferential width that is smaller than a distance between the first wall and the second wall of the slot, wherein one of the insertion portions contacts the first wall of the slot through an insulator, wherein another one of the insertion portions contacts the second wall of the slot through the insulator.

Abstract
In a vehicular alternator, a stator is arranged to oppose a rotor in a housing. The stator includes a stator core, which forms a plurality of slots extending in an axial direction of the stator core, and a stator winding wound around the stator core. The stator winding includes electric conductors held in the slots. Each of the electric conductors has a circumferential width that is smaller than a circumferential distance between a first wall and a second wall defining the slot. The first wall and the second wall oppose each other in a circumferential direction. The electric conductors are alternately in contact with one of the first wall and the second wall.
