基于气隙磁场的异步电机“全矢量”分析法

The Full Vectorial Analytical Method of Asynchronous Motor Based on Air-gap Magnetic Field

本文以气隙磁场为核心,根据矢量运算规律,详细推导了“全矢量”形式的异步电机动态模型;根据此形式的动态模型,以供电侧和控制端为出发点简单而直接地获得了控制方案。此方法在教学中有很好的专业知识承袭性,简化了控制方案确定的难度;它很容易推广到其他电机的矢量控制,使电机控制的教学更加系统化。

Based on the air-gap magnetic field as the core,according to the laws of the vector calculation,the dynamic model of asynchronous motor in the form of“full vector”is derived in detail.According to the dynamic model,the control method is obtained simply and directly from the supply side and control side.This method has a good inheritance of professional knowledge in teaching and simplifies the difficulty of determining the control method.This method can be easily extended to vector control of other motors,which makes the teaching of motor control more systematic.
