ABSTRACT:
A system for positioning the output shaft of a motor is disclosed having a set of terminals for receiving a predetermined count representing a desired position for the output shaft, a counter having first and second inputs, the first input being connected to the set of terminals, a count generator associated with the output shaft and connected to the second input of the counter for supplying to the counter counts dependent upon the rotation of the output shaft, and a switch connected to the motor and to the counter for energizing the motor when the counter receives a predetermined count representing the new desired position and for de-energizing the motor when the count generator supplies a number of counts equal to the predetermined counts.
