Variable Load Torque Performance Analysis in Flux Weakening Control of PMSM

This paper examines performance of a permanent magnet synchronous motor (PMSM) under various load torque conditions, when a flux weakening control strategy is imposed on the motor. Flux weakening is implemented by employing a vector control technique. The technique is simulated with the flux weakening blocks added to it. Torque and speed measurements are recorded. The performance of PMSM during different load torque conditions is analyzed as well.
