Summary:In order to provide a simply configured X-ray CT device in which the standby time until X-ray irradiation is permissible is reduced without detection of positive electrode rotation frequency, a control unit (23) selects a rated positive-electrode rotation frequency from amongst a plurality of types thereof in response to X-ray irradiation conditions, and supplies a drive current, which implements the selected rated positive-electrode rotation frequency, from a starter circuit (10) to a stator coil (81). The control unit (23) acquires the time required to arrive at an irradiation-enabling rotation frequency, which is less than the rated positive-electrode rotation, that is necessary for X-ray irradiation under the X-ray irradiation conditions. If the arrival time has passed, X-ray irradiation is permitted. Thus, X-ray irradiation can be initiated at the minimum permissible positive-electrode rotation frequency in response to the X-ray irradiation conditions, and the standby time, during which a user waits befo
