Effect of Winding Arrangement on the Electromagnetic Performance of HTS Squirrel Cage Induction Motor

Abstract

In this paper, a new structure of high temperature superconductor induction motor has been introduced which rotor bar is consisted of copper and superconductor material. The purpose of this paper is analyzing the effect of arrangement of three-phase distributed fractional pitched winding on the electromagnetic performance of HTS induction motor, which is mounted on the stator. So that, three types of distributed winding have been designed and analyzed for HTS induction motor, such as: On-layer, two-layer and three-layer. All analyses have been done by finite element method and Maxwell Ansys software at the same condition and geometry. All models are compared to each other in terms of airgap flux density, total harmonic distribution, flux distribution, synchronous torque, starting torque, ripple torque and efficiency.
