I have a 12v Brushed DC motor (not Permanent Magnet) that takes about 2.5A when heavily loaded.
I want to make (or buy a kit) that will drive the motor smoothly at slow speeds, and more or less maintain rpm under load. Also bi-directional.
My input supply range is up to 20V DC at up to 5A.
I think I may need a PWM controller. Preferably *not* based on a micro controller.
A speed controller allowing speed regulation seems to be the difficult bit when searcing for a suitable device, circuit or kit.
Any motor experts here that knows what I can buy that would do the job?
