Hi I’m looking at purchasing a stepper motor that runs on 7.2 Volts. I need it to do about 100 rotations per minute, and it shouldn’t be lifting any more than 5 pounds. I’ll be using it on a robot controlled by a RC helicopter controller. How would I connect (if its possible) the motor to the RC receiver? Also, what do you suggest I buy? I know I’ll need a stepper motor and a controller for that motor (to program it), but I’m not sure what will suit my needs best. And would I need a speed controller too?
I had considered a winch servo however I don’t think it’ll give me enough rotation. I have an ARDX Arduino starter kit, would that work as a micro-controller with the RB-Hit-53? Also, CBenson said you don’t carry RC controllable stepper motor controllers at the moment, but would there be any available in the near future? And if I wanted to run a stepper motor without the controller (say I didn’t want to program it), could it be connected to a speed controller?
We currently don’t actually carry any R/C controllable stepper motor controllers. To do what you want, you’d need to program a microcontroller to accept R/C input, then convert that to the stepper motor signal which is sent to the stepper motor controller and then to the stepper motor. If this is not possible, can you use a different technology?
An Arduino can control a servo motor, but you would need to power the servo separately since the Arduino’s pins cannot provide more than 40mA. You would connect the signal wire (yellow wire) and GND (black) to the Arduino. You would split the GND wire; one going to the Arduino, and the other going to the battery’s black wire, along with the red wire. We don’t see any R/C controllable stepper controllers from any of our suppliers, but it would make for a good product. We offer one product with a potentiometer which you can use to control a stepper motor: RB-Cyt-23.
A motor that seems appropriate to your needs is RB-Soy-21
If you would like to use servo signals, you will need to use a stepper motor controller along with a microcontroller to interpret the control signals and output the corresponding steps. We can recommend you parts for this design but first, we want to suggest that perhaps you would prefer to use a winch servo motor instead:
