    • A slip ring with which a pair of brushes make contact includes a conducting portion which extends along an outer periphery of the slip ring over an angle of preferably about 210 degrees, and a non-conducting portion which extends over an angle of about preferably 150 degrees. A conductor which forms the conducting portion has a ring-like shape and also forms the non-conducting portion. The portion of the conductor which corresponds to the non-conducting portion has a small radius such that it is buried in an insulating resin material, a window through which an insulating resin material is exposed, or a recess through which an insulating resin material is exposed. The ring-like conductor provides a balanced center of gravity to the slip ring. The conductor may also include two or more conducting portions and two or more non-conducting portions.
    • 一对刷子与之接触的滑环包括沿着滑环的外周延伸优选约210度的导电部分,以及延伸大约优选为150度的非导电部分 。 形成导电部分的导体具有环状形状并且也形成非导电部分。 对应于非导电部分的导体的部分具有小的半径,使得它被埋在绝缘树脂材料中,绝缘树脂材料暴露的窗口或绝缘树脂材料暴露的凹部 。 环形导体为滑环提供平衡的重心。 导体还可以包括两个或更多个导电部分和两个或更多个不导电部分。
