高温超导定子无铁芯感应电机电磁特性分析

近年来,世界各国对于超导技术纷纷投入巨资加紧研究与开发,抢占技术制高点,不断推动超导技术产生新的飞跃,超导技术的应用步伐也迅速加快.将高温超导技术与电机结合研制的超导电机具有明显的优势,但是超导电机若采用传统电机的铁芯结构,超导材料性能将受铁芯磁通饱和的制约.本文利用有限元分析方法对一台初步设计的定子无铁芯高温超导感应电机的电磁特性进行了仿真分析.

Electromagnetic Characteristic Analysis of High Temperature SuperconductorCoreless Stator Induction Motor

In recent years,countries around the world have invested heavily in research and development,seize the technological commanding heights,and constantly promote the superconducting technology to a new leap and superconducting technology applications are rapidly accelerating. The superconducting motor developed by combining the high temperature superconducting technology with the motor has obvious advantages.However, if the superconducting motor adopts the core structure of the traditional motor,the magnetic flux saturation will restrict the performance of the superconducting material.In this paper,the electromagnetic characteristics of a high temperature superconducting coreless stator induction motor are analyzed. The finite element analysis method is used to simulate the motor.
