Large-capacity rotating superconducting (SC) motor has bright application prospects in low-speed direct-drive applications such as wind power generation and ship driving. SC motors are classified into rotating and stationary seal SC motors, depending on whether a cryogenic coupling transmission device is used to achieve the transmission of cryogenic medium and the input of excitation power. Stator and rotor configurations and their advantages and disadvantages of rotating seal SC motors are analyzed and summarized, respectively. For stationary seal SC motors, typical topologies such as segmented-rotor flux-switching motor, field-modulation double-stator motor and single-excitation pole-divided motor are used as examples to reveal the essential reason for achieving stationary seal of the cooling system. Finally, the common problems faced by these two types of SC motors are discussed. From the configuration level of the motor, the strategies and methods of suppressing the influence of the armature reaction magnetic field on the SC coil are given for the stationary seal SC motors.
