DIRECT-CURRENT REVERSING MOTOR-AMPLIFIERS
Abstract:
A number of reversing d-c motor-amplifier circuits are proposed. Motor-amplifiers combine a d-c motor with a magnetic amplifier constructed on the motor stator. By this combination a 30-40 reduction in weight is obtained by comparison with the separate magnetic amplifiermotor system. Since in power magnetic-amplifier drives the problem of weight is a crucial one, motor-amplifiers combining all the positive qualities of magnetic-amplifier systems with a minimum expenditure of materials are of great interest. Although the article is concerned with combined circuits, all the circuits proposed can be made with the motor and the magnetic amplifier operating separately. Thus everything referring to motor-amplifiers is also applicable to power magnetic amplifier-motors. Author
