Eddy Current Field Analysis of Induction Motor Based on Finite Element Method

利用Maxwell 2D有限元分析软件,建立了二维的三相笼型感应电机的几何模型和有限元模型,对三相笼型感应电机进行了涡流场计算与分析,计算并输出了电机磁力线的分布情况、磁通密度以及涡流损耗分布云图等。该模型为进一步研究感应电动机在运行过程中的温升效应提供了基础性数据。

Using Maxwell finite element analysis software2D,this paper established the geometric model and finite element model of three-phase squirrel cage induction motor two-dimensional.Three-phase squirrel cage induction motor is calculated and analyzed to calculate eddy current,and the output of the motor magnetic field distribution,magnetic flux density and the eddy current loss distribution etc..It provides the basic data for further studying the temperature rise effect of induction motor in operation.
