Abstract
A motor control system for a rotating anode type of X-ray tube comprising an axially rotatable rotor provided with a radially extended target disc, an electrically wound stator encircling a portion of the rotor, and a motor controller electrically connected to the stator. The motor controller includes circuitry for initially energizing the stator a predetermined interval of time to accelerate rotation of the rotor, and then periodically energizing and de-energizing the stator at a frequency to utilize the inertia of the rotor and the target disc in maintaining the rotation of the rotor when the stator is deenergized.
