Hi,
I just purchased 2 used like new wheelchair motors off eBay for a project I'll be doing soon.
Most DC motors I've worked with have a red and black wire to indicate positive/negative, but with the wheelchair motor, it has 1 red/black thick wire, and then 2 small black wires, so 4 wires total.
After some reading around, people said that the 2 white wires, 2 black wires in my case, are used to stop the wheelchair from moving. But that's not my main issue.
My issue is, I'm trying to hook one motor up to a variable DC power supply (it supplies 15v max, with 2AMP) to just make sure the motor works before leaving this seller feedback and continuing on with my project. When I do hook the motor up to the power supply, the motor does not move at all, it just sounds like a short circuit is occurring, and I can see a little spark similar to when hooking car batteries up.
Now the motor is a 24VDC motor and supports up to 10A on a full load, so I'm wondering if I need to supply that much power to get the motor to move at all? In my experience, even if you don't supply the full 24VDC or whatever the motor is rated for, it will at least move, maybe at slower speeds, but it will move, but these two motors I cannot get to move at all, just sounds like the thing is braking or again a short circuit occurring...
So just looking for advice on what to do here?
