RC Control of DC Motors

Help & Support Robot Parts
1

I built large Meccano/Erector Models of Cranes and other Heavy Construction Equipment. All construction are in metal, so quite heavy when completed, in the range of 15 to 25 lbs. I bought from Robot shop; Some Vex Track systems and they are working just fine for my models.

My completed models are operated with 4 to 6 DC Gearhead motors, in low RPM (less than 100 RPM but with good torque power) and run usually very slow. I now run my motors with an external 12 VDC power supply, a long cable attached to a switch box to control all :sunglasses::cool:my motors. I want to get away with the external power supply, cable and the switch box and start to control my models and motors with some kind of wireless RC Device.

So I need to only control 4 to 6 DC Gear head motors at 12VDC, I must be able to control

  1. Motor speed. (Varied voltage!)
  2. Motor rotation in CW and CCW direction. (Change polarity of DCV)
  3. Put motor in the Stop position.
    That it is for now! No logic or programming of any kind (maybe later after this first initiation to wireless)

I know very little about Radio Control and even less about Robotic and programming.
Can you suggest a system and some components to do just that? (Transmitter, Receiver, Servo, Motor controller, etc?)

Will be getting system from Robot shop, I already have an account with Robot shop.

Thanks for your support.

Hi Jacques1944,

Welcome to the RobotShop Forum. We’d love to see images or videos of your project as is. Can you describe the current control setup? Are you using a main controller? Do you just want to use a handheld RC controller?

In order to choose motor controllers, you need to know each motor’s maximum continuous current (A) and nominal voltage. Can you compile a list so we can help you choose the right motor controllers?

Sincerely,
