Electromagnetic Characteristic Analysis and Optimization Design of a Novel HTS Coreless Induction Motor for High Speed Operation

In this paper. a novel HTS CIM was studied based on the minimization of the torque ripple and the perpendicular magnetic field component to the tape surface. The results shows that the performance of HTS materials is still not fully developed. but also needs further optimization. Based on the initial structure. the arrangement optimization design of the superconducting windings was carried out. The three-layer superconducting coils are rotated around the z-axis. After the calculation and comparison. the performance of the motor is best when the second layer rotates 18° and the third layer rotates 36°. According to the major electromagnetic characteristics of basic and optimized models. it verifies the effectiveness of the optimized structure.
