Research of a new structure of HTS DC Motor

This paper puts forward a new structure of the HTS DC Motor. This structure has no commutator and brush device, especially HTS material applied to the motor armature part, this can improve the overall efficiency of superconducting motor, solve the problem of the AC loss of motor. The 3D FEM software was used to set up a simplified model of the motor, through the simulation analysis, the structure is reasonable Hence this superconducting motor has a larger advantage compared with traditional structure of motor in the weight, volume, efficiency, loss, reliability. This advantage can be well applied in ship electric propulsion for HTS propulsion motor, play its important role in the field of transportation.
