To provide a rotary electric machine capable of obtaining a stable ground effect even under a contamination environment.SOLUTION: The present invention relates to a rotary electric machine comprising a ground structure in contact with a rotary shaft. The ground structure comprises: a mount member including a pair of stationary portions; a cleaning device installed in an upstream-side stationary portion with respect to a rotation direction of the rotary shaft; and a ground device installed in a downstream-side stationary portion with respect to the rotation direction of the rotary shaft. The cleaning device includes a broom-shaped brush which is installed in such a manner that a length direction of a rectangular cross section is substantially coincident with an axial direction of the rotary shaft, and the ground device includes broom-shaped conductive fibers which are installed in such a manner that a length direction of the rectangular cross section is substantially coincident with the axial direction of the rotary shaft. The cleaning device and the ground device are installed in such a manner that tip ends of the broom-shaped conductive fibers pass in contact with the inside of a region of an outer peripheral surface of the rotary shaft where a tip end of the broom-shaped brush passes in contact therewith, during rotation of the rotary shaft.SELECTED DRAWING: Figure 1
【課題】本発明は、汚損環境下においても安定したアース効果を得ることができる回転電機を提供することを目的とする。【解決手段】回転軸と接触するアース構造を備えた回転電機であって、アース構造は、一対の固定部を備えた取付部材と、回転軸の回転方向に対して上流側の固定部に設置された清掃装置と、回転軸の回転方向に対して下流側の固定部に設置されたアース装置と、を有し、清掃装置は、矩形断面の長手方向が回転軸の軸方向と略一致するように設置されたほうき状ブラシを有するとともに、アース装置は、矩形断面の長手方向が回転軸の軸方向と略一致するように設置されたほうき状導電性繊維を有しており、清掃装置とアース装置は、回転軸の回転時に、ほうき状ブラシの先端部が接触しながら通過した回転軸の外周面の領域内を、ほうき状導電性繊維の先端部が接触しながら通過するように設置されている。【選択図】図1
