He jury-rigged the wheel chair control system by making an interface board to send it signals like the joystick is still there. I'm not sure thats reliable. I will be using a spektrum BR6000 & dx6. I would design my own system with controllers but I'm having trouble finding ones that will handle the amps I will be using.I'm also having problems finding specs on motors. I found two that look like they would be perfect.They are off an Invacare E690a (left motor Part # 1039759) Invacare lists the motor but gives no specs.any ideas?
Well, links would still be nice. If I can get an idea what motors you are looking at, I can probably dig something up or find something better if it comes down to it.
I wonder if I can run the motors at 12 volts instead of 24? That would cut the Speed problem down some.BTW I am getting the whole chair FREE. The best thing....!!! LOLI intended on isolating the electronics inside a waterproof box to minimize the sparking/fuel hazards...
lowering the volts makes the motors weakerusing pwm keeps the torque the same but you can control speed
Hmm, this might be a silly question, but how does pwm for dc motors work exactly?If you have a 3V motor, and you want it to go at half speed, you pulse 3V, 0V, 3V, 0V, etc? Wouldn't that mean that when you pulse 0V the motor has no torque?
