Abstract
An X-ray source device includes an anode to generate X-rays; a drive to rotate the anode about an anode central axis, the drive including a stator and a first rotor, and the first rotor being rotationally fixed relative to the anode; and a cooling facility to cool at least one of the anode and the drive using a coolant. The drive includes a second rotor to circulate the coolant.
Claims23
An X-ray source device, comprising:
- an anode configured to generate X-rays;
- a drive configured to rotate the anode about an anode central axis, the drive including a stator, a first rotor and a second rotor, and the first rotor being rotationally fixed relative to the anode;
- and
- a cooling facility configured to cool at least one of the anode or the drive using a coolant, the second rotor being configured to circulate the coolant, wherein
- the drive is an axial flux machine, the first rotor being on a side of the stator closer to the anode in a direction of the anode central axis, and the second rotor being on a side of the stator farther from the anode in the direction of the anode central axis.
