    • [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).
    • 本发明的目的在于提供一种防止因安装于车辆用交流发电机或电动发电机的电刷的温度上升而引起的功能障碍,寿命缩短的旋转电机。 用于解决问题的手段保持向转子(1)供给励磁电流的电刷(8)的电刷保持器(80)具有与电刷(8)大致平行地设置的电刷温度抑制金属部件(81) 除了通电端子(82)之外的至少一个点处,电刷(8)和滑环(4)的抵接部分与电刷(8)点接触,线接触或表面接触。 电刷温度抑制用金属构件(81)不仅使电刷(8)产生的热扩散,而且在再生发电时等短时间内产生大量热量的情况下也起到热容量的作用 和启动操作,从而防止电刷(8)的过度升温。
