Abstract :
The torque capability of a salient pole PMSM drive is theoretically analyzed. The analysis is performed with a linear, stationary, model of the motor, assuming constant voltage boundary and continuous current limitations. General steady state torque and power characteristics are presented. A new controller which ensures maximum torque to current ratio in the whole speed range is presented. Simulations and laboratory tests support the theoretical analysis.<>
