  • Lead wire connection structure of rotating electric machine
    Patent number: 9627946
    Abstract: 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.
