Abstract
A position control system capable of relatively great positioning accuracy includes a universal electric motor and a gear box for transferring the motion of the motor and an object being positioned. The position control system includes a conductive brush which moves with the object being positioned and which slides on a plurality of electrical contacts which are part of a control circuit the control circuit includes a plurality switches for selection of the desired position of the object and resistance networks which serve to apply various values of voltage to voltage sensitive motor speed and direction controls which in turn control the speed direction and stopping of the motor hereby controlling the position of the object.
