摘　　要：交流电机三相绕组合成磁动势是电机学教学中的重要内容。通常,这部分的教学以纯数学计算的方式进行,计算方法较复杂,物理意义不直观,不利于学生对这部分原理的理解。本文利用空间矢量的概念进行数学推导,计算过程简单明了,物理意义直观明确。文章对交流电机内容的教学有一定的指导作用。The composite magnet-motive force of three phase windings of AC machine is an essential part of teaching electric machinery. Generally, the teaching of this part is mainly based on pure mathematical process, with complicated calculations, while its physical meaning is not straightforward, leading to difficulty for the students in understanding. In this paper, space vectors are utilized in the mathematical process, the calculations are simple and clear, and the physical meanings are concise and explicit. This paper can serve as a significant guide in the teaching of AC machine.
