Thread: Remote Control Wheel-Chair: HeLp

    Default Remote Control Wheel-Chair: HeLp

    Hey im new to this electronics stuff. Im trying to make a remote control lawnmower out of an electric wheel chair. Basically all i have from the wheelchair is 2 stepper motors im guessing. they both have 4 wires 1 black 1 red and 2 white. I also have a 2 channel transmitter and reciever. Im trying to find a power control box that i can use for the stepper motors that is inexspensive, but im not having much luck. Im not really sure how to wire the motors up also. if anyone can give me any advice or point me in the right direction id appreciate it thanx.

    They are not Steppers: they are DC motors, probably 24V with Tacho feedback.
    The red and black are + and -.
    Where did you get the chair?
    Can you post a pic of the motors?

    Hey, you can kinda see the motors in the link below it is a pride/Jazzy made chair. I have the joystick controller But not the other box that that plugs into. I was going to use the controller and the other box and just try to wire a 2 channel reciever to it but it dont have the other box. Do you know what i can use to control these two motors with a wireless transmitter? I will post a picture of what i have put together when i get the chance. I did try to hook the motor up to a 12 v battery. When i put just the black and red wires to the battery it didnt turn, but the wires got real hot. I also hooked up the black and red wires and the two white wires one to each side and it did move but not real fast, and if you switch the red and black wires around it changes direction. If you just hook up the white wires one to positive and one to negative it sounds like a relay or something clicks in the motor. Ill get a better pic of the motor if you need it. How do you post it on here? Thanx for the reply.

    I'm still waiting for the pics of the motors.
    Those are monster motors rated at 24 Volts and about 50A :!: :!:
    Thats quite some current and quite difficult and expensive to make the electronics !

    There ARE some shortcuts I can suggest, however......but first - the pics!

    Hi Sam!
    Thanks for the Pic.

    As I said, these motors are rated @24VDc/50A each, with Tacho o/p.

    They are Servo Loopback controlled and the Electronics is expensive.
    The simplest will be to control them through DC Relays (for experimants). The rating has to be 100A,
    The other alternative (and recommended, in the long run) PWM speed control driving a discrete High current H-bridge made of MOSFETs or IGBT. This will give you speed control as well as enhanced torque. The Transistors should have a Current rating of atleast 4 times the peak current.

    You still haven't spelled out the purpose.....
    Good luck!!!
