Glad to have found this forum. I've got a project going that doesn't really fit into the realm of "RC" but will most likely use all RC/Hobby type and size parts. My knowledge of this world is fairly limited and I would love some help from those of you that know this stuff like the back of your hand!
You see, I'm trying to get a motor (a small one, maybe brush-less?) to turn a small wheel/pulley (less than 5" in diameter) at a max speed of less than 20mph. The speed and direction would ideally be variable... remote control would be awesome!
On the topic of motors. If the pulley is over-loaded (ie if you stop it from turning by force) I'd rather if the motor didn't burn up. Am I right in thinking that this would be ok with a brushless motor? Am I totally missing something here?
From what I can gather, this is fairly low RPM (about 1300 I think) in the world of rc motors. That's ok, because I need a decent amount of torque. There are ways to get a higher RPM motor to turn more slowly and thereby produce more torque, right?
Also, I'd like to talk about batteries and battery life. Ideally, I could run this pulley for about 10 minutes before needing to recharge.
Lastly (and here's the part where you might have to laugh at me!) I'd like to put this contraption together for about $100.
So here are my (probably very silly) questions:
- Am I totally off-track?
- Can you get me on the right track?
- What do I need? (list of components)
- What kind of motor/ motor configuration would be best?
- How would I best put this together?
You see, I've made a really simple prototype but I'm stuck when it comes to getting it to operate the way I want (I'm touching wires together to make it go and clamping the thing together!) I also tried using a slot car controller, which works ok for this motor as far as varying speed, but wouldn't be useful for a brushless version. Lastly, the current prototype can't easily change direction. I need a switch or something in the next one to be able to do this. I'd appreciate any and all advice and thanks in advance!
