Abstract
The efficiency of induction motors decreases at light loads. Efficiency optimizer control systems
adjust the motor flux value to achieve the best efficiency in a wide range of load variations. Reduced flux
operation has some other benefits such as power factor improvement and torque ripple reduction. The latter is
an important issue in a direct torque controlled induction motor drive. In this paper, the effect of flux
reference value on the torque ripple of a direct torque controlled induction motor is analyzed. The effect of
flux value on torque ripple in a wide range of speed variations is investigated. Simulation and the
experimental results presented justify the validity of the theoretical analysis about torque ripple.
