摘要： To obtain a rotating electrical machine preventing a functional failure and shortening of the life of brushes caused by a temperature rise of the brushes installed to a vehicle AC power generator or a motor generator. A brush holder holding brushes supplying a field current to a rotor is provided with brush temperature suppressing metal members installed substantially parallel to the brushes in the vicinity of abutment portions of the brushes and slip rings in point-, line-, or surface-contact with the brushes at least at one point besides energization terminals. The brush temperature suppressing metal members not only diffuse heat generated at the brushes, but also function as a heat capacity for a case where a large amount of heat is generated in a short time, such as during regenerative power generation and a start-up operation, and thereby prevent an excessive temperature rise of the brushes.
