The electrical torque relations of DC motor and induction motor are presented in the paper.The basic concepts of vector control are introduced based on the torque relations.Finally,the idea and diagram of vector control are discussed in the paper.

• 本文首先对直流电动机电磁转矩和异步电动机电磁转矩之间的内在联系进行了介绍,在此基础上、给出矢量控制的基本概念,最后,讨论了异步电动机矢量控制方法的基本思想,给出了矢量控制系统的总体(思路)框图。
