摘　　要：叙述了交流永磁同步伺服电动机的基本原理 ,并给出电流、电压的基本方程式。运用坐标变换 (二到三和三到二 ) ,分析电流、磁通和转矩的关系 ,说明在矢量控制中 ,应该遵循的原则。最后 ,以光学编码器作位置传感器为例 。This paper states the basic principle of AC permanent synchronous servo motor,and gives the equation of voltage and current.Applying the coordinate conversion (two to three and three to two),analyses the relationship between the current,flux and torque,and explains the rules to be followed in vector control.As an example with optical encoder as position sensor,a flowchart calculating current has been given at last.

关 键 词：永磁同步伺服电动机 矢量控制 电流计算
