Abstract

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.
