Description

ABSTRACT:
A stator3of an on-vehicle AC generator1denoting a dynamo-electric machine has a stator core32having slots35arranged in a line along a circumferential direction of the stator core32, electric conductors which are inserted into the slots35to be protruded from an end surface of the stator core32in an axial direction of the stator core32and of which portions protruded from an end surface of the stator core32in an axial direction of the stator core32are bent in the circumferential direction, and an electric insulating member34which is arranged between an inner wall of each slot35of the stator core32and a peripheral surface of the electric conductor so as to surround the electric conductor and has at least two duplicate layers34A and34B formed by duplicating the electric insulating member34.
