A superconducting motor system includes a stator and one or more rotors inside the stator. The rotors may form a plurality of poles, and may rotate when a current is applied thereto. The one or more rotors include: a superconductor winding portion for each pole and in which superconductor coils are wound to form at least two layers; a power supply portion configured to supply a current to the superconductor winding portion; and a resistor portion connecting the superconductor winding portion at least partly in parallel to the power supply portion. the resistor portion enables different currents to be able to flow through the at least two layers of the superconductor winding portion.

Superconducting motor system

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.
