Abstract: An apparatus to produce accurately limited angular or pivotal movements of a shaft of a DC motor with a control circuit to supply appropriate signals to control the operation thereof. Position indicators are provided to detect the shaft position and a second indicator is located to detect a rearward pivot position. Means are provided to establish a direction signal to indicate direction of rotation of the shaft, and the direction signal means and the position indicators produce outputs which are connected to the control circuit. The DC motor has a motor drive which receives signals from the control circuit during movement of the motor between forward and rearward pivot positions. The control circuit produces, first, an acceleration current and then a deceleration and finally a correction current with the current dropping to "zero" when the desired angular position has been reached by the shaft.
