Abstract
A gantry drive includes a multiphase stator, a multiphase rotor, a tunnel-shaped cavity configured to receive a patient, and a controller. The multiphase rotor spatially surrounds the cavity. The multiphase stator and the multiphase rotor form a multiphase motor configured to produce a rotating-field power. A first portion of the rotating-field power provides a mechanical drive power to produce a rotational movement of the multiphase rotor, and a second portion of the rotating-field power provides an electrical supply power for a payload apparatus. The controller is configured to vary at least one of the first portion or the second portion.
