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 :)
if you can find an coaxial if you can find an coaxial audio jack with four contacts, you can run the signal wires up and over the motor, connecting from the top.
It’s actually not going to It’s actually not going to be spinning much, i only want it so if it needs to spin it can, without having to worry about wires. Essentially, I don’t see the speed ever going past about 10-20 RPM.
Do I connect the 4 wires to where the male part would be and then run that down to the main circuit where a fixed female jack would be? I’m just trying to visualize this.
Also do you know how many wires are inside a coaxial audio cable? If theres less than 4 would it be possible to use 2 of these cables?
There is a swivel connector that you connect to your phone handset to stop the cable from winding up. They are cheap, and and have four connections I believe. Should work well for low rpm applications.
