摘要：
A novel rotor structure with a set of compensation winding for line-start permanent magnet synchronous motors for high capacity and low speed, which can meet the requirements of a ball mill with a high moment of inertia, is proposed to improve the motor-starting performance. A control strategy for the compensation winding current is implemented to increase the synchronisation ability with a high-inertia load. The compensation current and its control method are analysed using a mathematical model and verified using a time-step finite-element analysis. The simulation shows that the permanent magnet motor proposed in this study can successfully start at a load of 15 times rotor inertia.
