Hi
I'm trying to find a way of transferring power and data between two rotating
devices (1500 rpm). The two devices rotate along a common spindle and are
separated by 5mm.
Connecting power between these two is easy by the use of some form of
commutator arrangement (you know, a couple of brushes and concentric copper
rings), but I don't know if this is a good approach to send the data as
well. I can envisage noise appearing on the data due to dirty brushes or
copper rings, or should I just try this and add more brushes for the data
ring?
The data rate is less than 1Mbps.
Ideally an inexpensive solution.
Thanks for any ideas.
