This paper describes a high performance full digital servo drive system of permanent magnet synchronous motor(PMSM) based ln the digital signal processor (DSP). The mathematical model of spindle PMSM is set up. Furthermore, the precise current vector control algorithm is proposed according to the vector change theory and flux weakening theory. By the analyses of the computer simulation in various spindle motion couditions, some optimum parameters and important conclusions are obtained, which have practical significance to the drive system design.
