三相变频笼型异步电动机定子结构振动优化设计

Optimized Design of the Stator Structure for 3 Phase Cycloconverter-fed Squirr el Cage Induction Motor

本文通过有限元方法对电动机定子在初步设计阶段进行了振动计算。经过理论分析和计算后，在恰当的位置修改尺寸，消除了危险频率。

The Calculating vibration of motor stator during primary design is presented in this paper by finite element method.Parameters are determined after theory analy sis and calculating.Danger frequencies are eliminated.
