Asynchronous operation method for rotating rotary anode installed in X-ray tube, involves applying rotational torque on rotor by adjusting stator voltage and stator frequency, by which efficiency of asynchronous operation is maximized

摘要

The method involves driving a rotary anode through an anode drive of a rotor and a stator. The rotational torque (M) of the anode drive is applied on the rotor by adjusting the supplied stator voltage and stator frequency of the stator in such a manner, by which the efficiency (W) of the asynchronous operation is maximized at the predefined target rotation speed (Fsoll). The stator voltage and stator frequency is determined and is adjusted from the pre-stored measured values (M1-M3,W1-W3) of the anode drive. An independent claim is included for rotary anode assembly.
