Abstract
A wire brush for a slipring includes a contact section, from which a stabilizer arm is extending backwards towards the brush block of the slipring. The stabilizer arm holds a friction section, which is in friction contact with the contact section at a friction contact area. Such contact, in operation, generates internal friction within the brush when the brush is moved and, therefore, suppresses oscillations of the brush.
