摘要:
An electrical machine includes a non-rotating part, a rotating part, at least one bearing that includes a rotating ring and a non-rotating ring and supports the rotating part, a grounding brush fixed and secured to the non-rotating part, and having a free end extending towards the rotating ring of the bearing, and a conductive layer covering a portion of a surface of the rotating ring of the bearing such that the free end of the grounding brush is in contact with the conductive layer.
