摘要： [Problem]
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.
[Means for Solution]
A brush holder (80) holding brushes (8) supplying a field current to a rotor (1) is provided with brush temperature suppressing metal members (81) installed substantially parallel to the brushes (8) in the vicinity of abutment portions of the brushes (8) and slip rings (4) in point-, line-, or surface-contact with the brushes (8) at least at one point besides energization terminals (82). The brush temperature suppressing metal members (81) not only diffuse heat generated at the brushes (8), 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 (8).

摘要： A control unit assembly A is located at a rearmost side, a brush unit assembly C is located at a frontmost side, and a power unit assembly B is located between the control unit assembly and the brush unit assembly, respectively. The control unit assembly, the brush unit assembly and the power unit assembly are incorporated in a rear bracket 5. The rear bracket, the control unit assembly, the power unit assembly, and the brush unit assembly are integrated to configure a rear side semi-manufactured assembly D. In a controller-integrated electric rotating machine configured to assemble a front side semi-manufactured assembly E formed from an electric rotating machine main body 1 and a front bracket 4 with the rear side semi-manufactured assembly D, a series of brush restricting pin insertion holes 24 are disposed from a rear side end surface of the control unit assembly through the brush. Assembling workability is improved without failures in assembling work which occur due to breaking away of a brush from a brush holder to the rotary shaft side.
