Research on Servo System for CNC Machine Tool Driven by Permanent Magnet Synchronous Torque Motor

Abstract:

Permanent Magnet Synchronous Torque Motor (PMSTM) has the main characteristics of low speed, high torque, high precision and excellent stability, which can be applied to implement the direct driving technology for CNC (Computer Numerical Control) machine tool. In this paper, the mathematical model of PMSTM is simply introduced, and the various control strategies are discussed in detail. According to the requirement of high performance for PMSTM driving servo system in CNC machine tool, the corresponding suitable control method is employed in the feed servo system. The proposed scheme is also promoted to apply in the spindle system, the tool holder and the turntable of machine tool.
