Abstract: An x-ray emitter has a rotating envelope x-ray tube that is rotatably mounted on a shaft in an emitter housing filled with a cooling and insulating agent, and a drive apparatus coupled to the rotating envelope x-ray tube by the shaft. The emitter housing is hermetically sealed and the drive apparatus includes a predetermined number of permanent magnets as well as electromagnets corresponding thereto. The permanent magnets are arranged within the emitter housing and alternate annularly around the shaft in terms of their polarity. The electromagnets are arranged on an exterior of the emitter housing and can be controlled by a control and regulating unit to produce a rotating alternating field. The x-ray emitter is suited to high rotational speeds and/or to high pressures of the cooling and insulating agent in the emitter housing.
