Lead wire connection structure of rotating electric machine

摘要

A lead wire connection structure includes a rectifier that is arranged at the outside or the inside in an axis direction of the brackets so as to rectify AC voltage, which is generated on the stator, to DC voltage; in which, when a number of conductors of a connecting portion, at which lead conductors of the stator winding and the rectifier are connected, is “N” (N is integer and greater than or equal to 2) per one position, conductors, of which number is less than or equal to “N−1” per one position, are connected at the connecting portion, and conductors excepted from the conductors, of which number is less than or equal to “N−1”, are welded onto the remaining conductors at a position being nearer the stator winding side than the connecting portion.

主权项

1. A lead wire connection structure of a rotary electric machine, comprising:
a housing that is composed of a front bracket and a rear bracket; a rotor that is fixed to a shaft, which is supported between the brackets, so as to be rotatably arranged in the housing; a stator that includes a stator core having an annular shape, which is sandwiched by the front bracket and the rear bracket so as to surround the rotor, and a stator winding which is mounted on the stator core; and a rectifier that is arranged at the outside or the inside in an axis direction of the brackets so as to rectify AC voltage, which is generated on the stator, to DC voltage, wherein a connecting portion, at which lead portions of the stator winding and the rectifier are connected, comprises at least two conductors extending from the stator winding per position, wherein at least one conductor of the at least two conductors is connected to the rectifier at the connecting portion, and wherein the remaining conductors of the at least two conductors are welded onto the at least one conductor at a position nearer the stator winding than the connecting portion.
