摘要/Abstract

摘要： 从输入电源谐波的影响角度分析,通过ANSYS软件对具有不同气隙宽度、相同输出容量的三相感应电机进行仿真,从而得出不同谐波种类下及谐波含量下的三相感应电机的转矩特性曲线和功率特性曲线。经过多元线性回归得出三相感应电机效率与气隙宽度、谐波种类、谐波含量和转矩变化之间的关系公式,适用于普遍的三相感应电机效率计算。

关键词: 三相感应电机, 谐波含量, 电机效率

Abstract: Based on the analysis of the harmonic effect of input power supply, the three-phase induction motor with different air gap width and same output capacity is simulated by ANSYS software. Thus the torque characteristic curve and power characteristic curve of three-phase induction motor under different harmonic types and harmonic contents are obtained. The relationship between the efficiency of three-phase induction motor and the width of air gap, the type of harmonics, the content of harmonics and the variation of torque is obtained by multiple linear regression, which is suitable for calculating the efficiency of three-phase induction motor.

Key words: three-phase induction motor, harmonic content, motor efficiency
