Abstract
A slip-ring brush includes a holder and a brush element that has three regions. The brush element is joined in the first region to the holder, and exhibits a cross-sectional geometry having a cross-sectional area in the second region, which is predetermined for the contacting with a slip ring. The brush element has the same cross-sectional area in the third region as in the second region. The brush element is additionally arranged such that its third region is disposed between the first region and the second region. The cross-sectional geometry of the brush element in the third region is shaped so that it deviates from the cross-sectional geometry of the second region, to reduce the effective spring stiffness of the brush element.
