Need help with rotating electrical connection!
January 22, 2010
I'm doing a project and would appreciate some help. I essentially have a DC motor controlling a blade from the center. On the blade is a sensor that I need to wire to the main circuit that is below the DC motor. The problem is when the blade rotates the wires will obviously tangle.
I know slip rings may work but I hear they are generally expensive and very noisy. I have read on some things like using audio jacks with maybe some coaxial cable. The sensor has 4 connecting wires, and whatever the rotating mechanism is, won't be able to be placed at the center because that's where the motor is, or am I wrong?
I'd really appreciate if anyone could help me. Thanks :)
