Abstract
An alternator according to the present invention includes: a shaft; a rotor that is fixed to the shaft; a stator that has a stator core that is disposed so as to surround an outer circumference of the rotor and in which a plurality of slots that extend axially are formed so as to be spaced apart circumferentially; and a front bracket and a rear bracket that hold circumferential edge portions of the stator core from two axial ends using a plurality of holding means and that envelope the stator core, a pair of first stays that are formed on the front bracket being fixed to a vehicle by bolts that penetrate through a pair of penetrating apertures that are respectively formed on the first stays, and the pair of penetrating apertures are formed at positions such that an approximate perpendicular bisector of a straight line that connects centers of the penetrating apertures intersects an axis of the shaft; and one of the holding means is disposed on the perpendicular bisector near the shaft. This configuration can prevent generation of magnetic noise without increasing weight in the brackets, in other words, without increasing overall weight.
