Rotate a Shaft - 60-120 Seconds Per Revolution - Bidirectional
August 30, 2012
I need to rotate a shaft very slowly. Somewhere between 1 and 0.5 RPM. I need forward and reverse. I don't need position sensing. External control will be two buttons -- forward and reverse.
I'm aware I could use a stepper motor and a controller, but that seems overly complex for my application. I need close to 360 degrees of rotation and I'd *prefer* that it rotate in either direction as long as power is supplied, so a servo motor seems like a poor match.
There is a high probability it will get totally destroyed in the first few iterations of development, so something that's in the range of $10 is better than $100. (It is at risk of getting fried by nearby high-voltage RF, if I mess up construction.)
What would be an appropriate motor/gear/whatever?
