Hi
I am using paint-brush-like (metallic) brushes on a rotating coil as a connection for current path. Problem is if I connect the other ends of the brush to the ammeter, the readings are pretty noisy. I believe that as the motor runs, the brushes get disconnected at some point. Can anybody suggest a better connection to the current path?
