Pride Go Chair / Jazzy Z Chair drive motor wires

I have 2 motors from a wheel chair. It has 6 wires.
1 black, red (positive and negative)
2 yellow
2 white
I’m trying to figure out what the yellow and whites are for.

Hi @Oseller707 ,

I guess two of these are for the brake and two others could be temperature sensor?

I guess your motor has a brake and you cannot freely turn it by hand?

Here is what AI says:

That wiring configuration is a little less common for wheelchair motors, but it’s still possible. Here’s the most likely scenario and how to approach it:

Wire Identification:

  • Thick Red and Black: These are your main power wires. Red is positive (+), and black is negative (-).
  • Thin White (2 wires): These are likely your brake wires. Wheelchair motors often have electromagnetic brakes, and these wires control them.
  • Thin Yellow (2 wires): These could be either:
    • Speed sensors: Some motors have speed sensors that provide feedback to the controller.
    • Thermal protection: They could be connected to a thermal switch that cuts power if the motor overheats.

Yes, the motor has a mechanical brake lever and if I move it I can rotate the wheels. So it sounds like I need to put 24v to the 2 white wires also, or physically disable the brake. I think the 2 yellow wires are speed sensors. Need to do some testing.

Yes, sounds like that! Let us know when you find out.

I connected 24v battery to red and black cable from the motor and it started spinning. That was the only 2 wires I needed to connect to battery for motor to spin.

The 2 blacks are electronic brake, but I manually disengaged brake.

Weirdly, if I put the motor horizontally like in its normal position, it won’t spin. But if I put the motor vertically, it spins. Any idea why?

Maybe because of the brake.

Maybe when you put motor vertically, brake falls down and cannot block the motor from spinning?

Or some electrical contacts are moving?

I have to look because even with vertically or horizontally I can still spin it free with hand with minimal effort.

Plus with horizontal that’s its normal position. Both wheels on ground.

Ah ok, if you can spin it free with hand, then it is not the brake. Maybe there is no good electrical contact inside when motor is in vertical position?

Weird thing is both motors doing the same thing. Need to take it apart and look inside. Could use a cleaning anyway.

Great, let us know :slight_smile:

I think this is the final update for now. It turns out you can remove the back section of the motor. Where the 2 yellow and white wires are. The 2 yellow were connected to a microswitch, and the 2 whites I think as electro brakes. I moved the brake lever to disable so the brake is off, then pulled out the whole electro magnetic assembly by removing the 4 screws. Now only the red and black positive and negative cables remain, and this works still. The brake is permanently always off.

This is what I removed.

Great. What is the microswitch doing? Is it also from the brake? Detecting if the brake is open or close?

14

From what I can tell, the microswitch is for brake because when I move the lever, it also ‘toggles’ the microswitch, so its like a brake on/off.
This is my understanding.

  • 2 white wires to electronically turn brake on/off

  • 2 yellow wires to let motor know whether brake is on/off. The state of the brake.

I wonder if i can control these 2 motors with a L298N motor driver. probably not.
Even if yes, not continuously before the L298N overheats.

I think it is better to use some of Sabretooth drivers or similar:
