Abstract
A slipring comprises a slipring module rotating about a rotation axis, having a plurality of sliding tracks and at least one multi wire brush sliding thereon. The sliding tracks have a circular contact surface with its center located at the rotation axis and a convex shaped cross-section. Due to this convex shaped sliding track, the individual brush wires of the multi wire brush distribute over the sliding track surface and offer a higher number of contact points. This results in a higher current capacity, lower contact resistance and lower contact noise.
