As a key component of feed system of CNC engraving and milling machine, the performance of control method of the permanent magnet synchronous AC servo motor(PMSM) plays an important role in the servo system. The mathematical model of PMSM is established and the vector control principle is described in detail. The current and speed double closed loop control of the servo motor is realized by using the DSP controller. The motor speed, current and angle are tested in control system are tested. Finally, verify the feasibility and accuracy of this control method by contrasting the results of motion control simulation with results of experiment, and providing theoretical basis for the control of the motor and the application in the NC machine tool.
