Michael, For 25A it should be OK to use a controller as used for RC (Remote Control) or bike/scooter motors, though the majority of those controllers are for AC motors, not DC. Before going down the path of how to provide reversing, we first need to know how you are going to control the controller: is there a speed control dial and a direction switch or how is the setup? Is it all digital (CNC type) control?

I have an Atlas metalworking lathe. I'd like to put a motor on the lead screw to get much lower traversing speeds than the lathe's internal gearbox will allow for. This is a relatively common modification to these little lathes. I have a 190RPM 12V DC gearmotor with a stall current of 25A that I'd like to use. It was a seat adjustment motor for a car, so it should be plenty torquey enough for this job. Does anyone know of an off-the-shelf, continuous-duty, reversing controller that would work with this type of motor? I can provide an AC-DC power supply to run it off of 110VAC. I just need the controller itself and don't really feel up to the job of building my own. Thanks in advance for any help anyone may be able to provide! -- Auf wiedersehen!
