摘要： A three-phase alternating-current winding is constructed by forming winding phase portions into a Y connection. The winding phase portions are divided into first and second winding divisions. Outputs from the first winding divisions are rectified and output by a first rectifier, and outputs from the second winding divisions are rectified and output by a second rectifier. In addition, a magnetizing electric current supplied to a field winding is adjusted by a voltage regulator such that the output from the second rectifier becomes constant.

摘要： A supporting member is an annular molded resin body integrating a brush holder and a rectifier circuit board. First and second heat sinks mounted with unidirectional conducting component packages constituting a rectifier and a voltage regulator circuit board constituting a voltage regulator are supported by the supporting member. The rectifier and the voltage regulator are mounted by fastening mounting screws that pass through mounting apertures of a mounting portion of the supporting member to a rear bracket.

摘要： An automotive alternator secures a fastening force for a vehicular connecting terminal for an extended period of time, and restricts the axial displacement of an output terminal, thus ensuring higher reliability. The output terminal is press-fitted and secured in a through hole in a first cooling plate, and the takeout end thereof is drawn out of an opening of a rear bracket. A metal bush is loosely inserted in an insulating bush and externally fitted to the output terminal, and the vehicular connecting terminal is fasteningly secured to the metal bush by a nut. With this arrangement, the fastening force of the nut is received by the rear surface of the first cooling plate via the metal bush. A flange of the metal bush is positioned so that a gap is provided between the flange and the insulating bush. The axial displacement of the output terminal is restricted by the flange abutting against the insulating bush.
