Abstract 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
