ABSTRACT:
The invention relates to an X-ray apparatus, comprising a circuit arrangement for accelerating and decelerating the rotary anode of a rotary-anode X-ray tube in which phase-shifted alternating voltages can be applied to the stator windings of the drive motor for the rotary anode in an acceleration mode and a direct voltage acts on at least one of the windings in a deceleration mode, and also comprising a control device for the acceleration mode and the deceleration mode. A particularly simple construction is achieved in that at least one of the stator windings is connected to a voltage source which supplies a periodic alternating voltage in a first operational state and a pulsating direct voltage in a second operational state, that a diode arrangement which can be switched on and off is connected in parallel with this stator winding with a polarity such that it is operated in the reverse direction by the pulsating direct voltage source and that in the acceleration mode the control device keeps the alternating voltage source in the first operational state and switches off the diode whereas in the deceleration mode it keeps the alternating voltage source in the second state and switches on the diode arrangement.
