What is the best way to slow down a dc Electric Motor like the one I've linked below?
I'm using this motor to turn a conveyor belt: http://www.radioshack.com/product/index.jsp?productId=2911245
I want the motor to turn the belt very slowly. What do you think is the best way to do that? Should I use resistors? Or something else?
Specifically, could you suggest the part on the RadioShack website? Thanks!
There are 2 effective ways to slow down a motor like this. Just lowering the voltage will reduce the power available to the motor and it won't run smoothly. You can use a gearing system or you can use a pulse width modulated control. PWM allows for smooth speed control and good power. The link below leads to an excellent PWM circuit tutorial. It's short and deals directly with controlling a motor speed.
