1. A gantry drive comprising:
a multiphase stator;
a multiphase rotor;
a tunnel-shaped cavity configured to receive a patient; and
a controller
wherein the multiphase rotor spatially surrounds the tunnel-shaped cavity,
wherein the multiphase stator and the multiphase rotor form a multiphase motor configured to provide a rotating-field power,
wherein, 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, and
wherein the controller is configured to vary at least one of the first portion or the second portion.
