ABSTRACT:
An induction motor is coupled to a movable load to be positioned. The induction motor has two or more stator windings. Alternating current power is connected to the stator windings to energize the motor. A transducer senses the position of the load. Responsive to the transducer, the alternating current power is disconnected from the stator windings as the motor approaches a predetermined load position. Also responsive to the transducer, a direct current energy storage device is connected to the motor as the motor approaches more closely to the predetermined load position to apply direct current to the stator windings and to stop the motor at the predetermined load position. Preferably, the storage device comprises a capacitor connected in series with a rectifier across two input terminals of the motor and the storage device is connected to the motor by a relay coupled from the junction of the rectifier and capacitor to one of the input terminals of the motor.
