介绍一种用高速数字信号处理器（DSP）控制的全数字化电主轴永磁同步电机交流伺服驱动系统。根据矢量变换理论和弱磁控制理论，提出一种高效精确的定子电流矢量控制策略。通过对电主轴各种运行情况进行计算机仿真研究，得出一些重要结论。

This paper describes a high per-formance full digital servo drive system of per-manent magnet synchronous motor (PMSM )based on the digital signal processor(DSP). Theprecise current vector control algorithm is pro-posed according to the vector control theory andflux-weaking theory. By the analysis of thecomputer simulatio11 in various spindle motionconditions, some important conclusions are ob-tained-
