we have 2 slip rings we have change inthe last 2 months . we use a vfd on 1hp 3phase motors. neither vfd use vfd cable to the motors [200'plus]. each slip ring had a hole burned into the slip ring track the brushes follow. slip ring is rated for 35 amps. i don't know if the vfd has the motors overloads set into it. could the vfd have damage the cluch on the shaft . i have heard of shaft currents and was thinking if that could be a cause. thak you for any help
