Re: [sudo-discuss] wheelchair motor controller

wow, you have done well. the answer is that it detects the missing wheel because it can't see its BRAKE electromagnet. the solution is to connect a resistor to the place where the other motors' brake coil would connect. it should be a resistor of a similar value to the brake coil on the motor you do have, or maybe more ohms so it uses less power when it gets energized. a lightbulb might work, but it will see 24VDC when energized, so it would need to be a 24v bulb or two identical 24v bulbs in series. as for the anderson connectors on the motor controller, please don't cut them or mess them up - if you need to connect to them (for example to connect to the brake contacts for the missing motor) there should be other anderson terminals in the basket where the motor was. Thanks for not hacking up the wires on the motors controller. and congratulations, you're close! once it works, we can use the other electronics (this is from an old robot) to automate the process of sending the screen up and down. -jake On Wed, 15 Jul 2015, Robert Benson wrote: Hey all, I'm trying to build a winch for the 14' projection screen that > going up over the ballroom stage out of a wheelchair motor assembly.
