In this paper, an event-driven simulation method is proposed for the motor driver in a virtual machine tool system (VMT), of which simulation speed is always a puzzle. This method utilizes a set of pre-defined events to trigger the execution of simulator in a non-deterministic manner and at the most efficient moment. Comparing to the conventional time domain simulation method, it dramatically reduces the CPU time consumption without losing simulation accuracy, therefore it improves the simulation efficiency. The effectiveness of this method is verified through a PMSM (Permanent Magnet Synchronous Motor) motor driver model in studying Servo/Mechanical interaction within a VMT.
