Abstract

The purpose of this paper is to find out the three-dimensional (3D) magnetic field distribution inside the motor in order to determine if the high-Tc superconducting (HTS) tapes operate stably in actual motor operation. With this goal, magnetic field distribution in a detailed model of the actual motor was analyzed through Finite Element Method (FEM). The field current of 4 A is the amount of current needed to achieve 600 AT required by the previous simulation aimed at developing this motor. Also, it has been observed that the flux damper reduces armature reactance during the motor operation and during load changes, improving the stable motor operation. And, it was observed that the flux damper generates loss by means of leakage flux, but this is not significant and it doesn't degrade the performance of the HTS synchronous motor.
