  • System for controlling operation of the rotating anode of an X-ray tube
    Patent number: 3963930
    Abstract: A closed loop system is disclosed for monitoring and regulating the power applied to the stator of an induction motor for controlling the operation of the rotating anode of an X-ray tube in order to insure acceleration of the rotor to a selected speed of rotation, to maintain the selected speed of rotation, and to provide a braking voltage to the rotor as desired. The system provides direct inter-related operation of an anode rotor, an anode rotor rotation sensing detector, and an X-ray generator.
