Hi....I've seen various posts a couple of years old on this, yet none that appeared to have any effective subtleties on driving an motor. I need to track down an motor to supplant the normal AC engine on the sewing machine. I should have the option to precisely control the speed of the motor. I've worked a little with stepper motors, yet I can't get the rpm I need for the sewing machine engine. (Around 1200 RPM). It not genuine quick, yet it appears to be quicker than the functioning scope of steppers. So is my lone other alternative a DC motor with an encoder appended? I'm not having a lot of karma looking for a little engine like this. Does anybody have any involvement in exact control of an engine cap may work for this application?
