Controller for regulating the speed and reversing the spin of AC motor at set intervals?
I would like to build a roller base that requires constant spin, and intermittent reversal of spin direction. In addition, the spin speed should be controlled so I could tune in different rpms ... eg range from 10-100. I am totally new to electromechanics and I do not know where to start. Just buying a motor and connecting it to AC should not be a problem, but the additional control seems tricky..
How can I control the spin/rpm of an AC motor, and how can I reverse the spin direction at controlled intermittent times?
