实心转子异步电机机械特性及涡流效应分析

在实心转子异步电机中,存在着复杂的电磁现象,如涡流现象、饱和现象、集肤效应等。本文利用有限元数值计算方法,对其进行了深入研究,并与用磁阳抗法及实验法所得的结果作了比较。结果表明数值计算方法的精确性,证明实心转子异步电机的机械特性与具有高转子电阻的普通异步电机的特性相类似,且具有良好的起动特性。

Analysis on Mechanical Performance and Eddy Effect for Solid Rotor Asynchronous Motor

In induction motors with solid rotors there exist complex electromagnetic phenomena, such as eddy current, saturation, skin effect, etc. By applying FEM, their mechanical performances, skin effect and eddy currents are analyzed. It is found that the results obtained from the FEM are much accurate than those obtained from the reluctance method and test method.
