异步电动机负载时高频附加损耗的分析与计算

Induction Motor Load Analysis and Calculation of High-Frequency Additional Losses

利用有限元的方法对异步电动机定、转子铁心和气隙的磁场分布进行了计算,并利用所得数据替代目前计算异步电动机负载时高频附加损耗所使用的经验值,计算出高频附加损耗的值,通过对计算结果的分析找到了降低某系列电机高频附加损耗的方法.

The paper uses finite element method to calculate the magnetic field distribution of induction motor stator core,rotor core and air gap;then use the calculated data to replace the experience value used in the calculation of high frequency loss from induction motor load ;and thereby figure out the high-frequency additional losses. According to an analysis on the results,we find out a way to reduce the high-frequency additional losses of this series of induction motors.
