摘要： An alternator for a vehicle is disclosed as having front and rear frames supporting a stator having a stator winding, a rotor fixedly carried on a rotary shaft and rotatably disposed inside the stator while having a field winding, a bush unit accommodating brushes held in sliding contact with slip rings formed on the rotary shaft, and a brush-wear particle collecting section for collecting brush-wear particles resulting from sliding contact between the brushes and the slip rings. In one embodiment, the bush unit includes a bush holder holding the bushes and a sealing plate member having the brush-wear particle collecting section. In another embodiment, the rear frame carries a protective cover formed with the brush-wear particle collecting section. In a further embodiment, the rotary shaft carries thereon brush-cooling means formed adjacent to the slip rings for creating an air stream to cool the brushes.
