| It would help a lot if you said what kind of motor. The Control of different types of motors are Totally Different types of controls. Gary | |

| Hi Attached is a simple speed control that uses either a 555 or 7555 IC. The IC can only operate at a max of 200ma, so if your motor draws more than that maybe you could use a transistor switch-Im not sure.But if your motor draws less than 200ma then this circuit should do the job. Hope it helps. :wink:

| unfortunatly that cct will not control the speed. For true speed controll you need speed feedback and a closeloop system the "error" of the demand and the speed feedback then can be used to drive something like the 555 cct above | |

| Thanks styx I see what you mean.This is just a basic speed control circuit that I found out of a book.Its not the best design for true speed I must admit.
