Abstract
An X-ray generator includes an X-ray tube, a blower fan having a motor and configured to provide the X-ray tube with air, a motor control unit configured to control a rotation speed of the motor, and a casing to which the X-ray tube and the blower fan are attached. The motor control unit shifts the rotation speed of the motor from a resonance frequency of a structure including the X-ray tube and the casing. According to this configuration, a resonance phenomenon caused by vibration generated by the motor is avoided. Therefore, influences of vibration on the X-ray tube are reduced. As a result, the X-ray generator can be operated in a highly stable manner.
