I'm faced with a problem of powering a device on the non stationary side of a rotating joint.
I know the traditional solution is brushes, but would it be possible to use a bearing for this purpose? Would a bearing be always connected even while rotating?
I'm asuming a small ( 10-20mm outer diameter) ball bearing, but any type might do.
If this would work, would the bearing withstand say, 24V @ 1Amp? Or even 1.5Amp?
I'm going to do some experiments into this, but I'd like to know if anyone tried.
