ABSTRACT:
An x-ray tube includes a housing enclosing a vacuum chamber, a cathode positioned within the vacuum chamber configured to emit electrons, and an anode positioned within the vacuum chamber to receive the electrons emitted from the cathode and generate a beam of x-rays from the electrons. The x-ray tube also includes a magnetic coupler drive configured to rotate the anode, with the magnetic coupler drive having an inner rotor frame positioned within the vacuum chamber and an outer rotor frame positioned outside the vacuum chamber and adjacent the inner rotor frame. The magnetic coupler drive also includes an inner rotor magnet mounted to the inner rotor frame and an outer rotor magnet mounted to the outer rotor frame. The inner and outer rotor magnets interact to generate a magnetic field that transfers torque from the outer rotor to the inner rotor, thereby causing the inner rotor to rotate the anode.
