Abstract
An electric control motor which utilizes a reduction type of gear train to provide output motion to a shaft for positioning devices such as valves, dampers, and other similar equipment is disclosed. This type of control motor is limited in rotation of the output shaft to less than 360 degrees so that the shaft can be used as a positioning force in numerous control applications. The total number of angular degrees rotated by the output shaft of the motor is readily adjustable by changing a potentiometer setting. In order to protect the motor, the linkages, and its load, a limit switch is also provided. A single stroke adjusting linkage that has a readily accessable location is used to concurrently set the stroke potentiometer and the limit switch so that the output shaft of the control motor is limited in movement to a predetermined number of angular degrees.
