Reducing Cogging Torque and Torque Ripple in Dual-Stator Permanent Magnet Vernier Motor by changing Rotor Rib Design

This paper has researched on a dual-stator permanent magnet vernier motor’s cogging torque and torque ripple analysis for a wind turbine. Because beginning torque lowers generating power in generator mode, it’s crucial to reduce cogging torque and torque ripple. The attraction between the steel teeth of the stator laminations and the permanent magnets installed on the rotor is an important factor to cogging torque. The thickness of the rotor’s ribs could be a factor that is studied to determine whether it has an impact on cogging torque and torque ripple. Both cogging torque and torque ripple reducing effect factors are suggested. Moreover, verifying the characteristics of torque ripple and cogging torque through experiment.
