One of our concerns at first was the fact that there could be full current load with no rotation. In a motor the rotation cleans the brushes and uniformly wears the commutator. In a slip ring for a swerve unit the rotation could be described as sporadic. We were concerned with arcing, pitting of the commutator ring, fusing of the brush to the ring, etc. This is why we used clear polycarb housings on the original prototype. But after running the slip ring for extended test cycles and after disassembly and inspection we found there was no reason for our concerns.
