To provide a rotary rectifier, a rotary electric machine, and a rotary electric machine system for dump trucks that reduce the number of parts and cost and save space as a shaft voltage countermeasure for excitation type rotary electric machines when an AC exciter system is used.SOLUTION: There is provided a rotary rectifier comprising a shaft rotatably supported by a frame, an AC exciter that is fixed to the shaft and rotates, a slip ring that is fixed to the shaft and rotates, and is equipped with an element that rectifies the current output from the AC exciter, and a carbon brush that slides against the slip ring at the radial end of the slip ring. In the rotary rectifier, insulating layers are provided on both axial sides of the slip ring, the elements are circumferentially arranged on one axial side of the slip ring, and the insulating layers are provided and fastened between the element fastening parts and the slip ring.SELECTED DRAWING: Figure 4

    【課題】ACエキサイター方式を用いた場合の励磁形回転電機の軸電圧対策として、部品数、コストを低減し、省スペース化を実現する回転整流器、回転電機並びにダンプトラック用回転電機システムを提供する。【解決手段】フレームに回転可能に支持される軸と、軸に固定されて回転する交流励磁機と、軸に固定されて回転し、交流励磁機から出力される電流を整流する素子を搭載するスリップリングと、スリップリングの径方向端部でスリップリングと摺動するカーボンブラシを備え、スリップリングの軸方向の両面に絶縁層を設け、スリップリングの軸方向の一方面に素子を周方向に配置し、素子の締結部品とスリップリング間に絶縁層を設けて締結したことを特徴とする回転整流器。【選択図】図4
