A motor that is a wound field synchronous motor and includes a rotor and a stator. The rotor includes a plurality of winding portions configured to have a preset cross-section for generating a uniform effective air gap. The winding portions are spaced from each other a predetermined distance apart along a circumferential direction of the rotor. A field coil is wound around the plurality of winding portions.

Motor

A motor includes a stator on which an armature coil is wound, a rotor disposed inside the stator, a superconducting field coil being wound thereon and, a controller configured to control the motor, in which the controller is configured to control an armature current supplied from an AC source to the armature coil and a field current supplied from a DC source to the field coil, and charge at least a certain ratio of the field coil before starting the motor.
