Abstract: The invention concerns a motor controller for a motor with a feedback potentiometer, preferably for central air valve actuation. In the field of climate control, for example for utility vehicles and motor vehicles, the air ducts in heating, air conditioning and/or ventilation systems have valves to control the flow of air or water. These valves are adjusted either mechanically, e.g. by Bowden cables or flexible shafts, or using motors. It is proposed that a continuous rotation potentiometer be employed as a feedback potentiometer and specially designed control electronics be used to control a motor with the continuous rotation potentiometer. In the control electronics for the motor controller, an angular difference between an adjusted control potentiometer and the motor feedback potentiometer is determined in order to determine therefrom the shortest adjustment path to the chosen setpoint position for the motor when the angular difference is greater than 180 degrees.
