Abstract

Torque pulsations such as torque ripple produce magnetic vibration and noise in permanent magnet machines. Thus, it is important to minimizing the torque ripple in permanent magnet generator design. This study reports a novel strategy in order to minimize the torque ripple in the 24-slot 16-pole radial flux inset permanent magnet (RFIPM) generator by using a geometric modification on magnet poles and stator teeth. We proposed four model of RFIPM generator with stator teeth notch and edge-rounded magnet (ERM) poles. Finite element method magnetic (FEMM) are used for computation of the torque ripple. We found that the modification of stator teeth notch and ERM poles significantly lowered the torque ripple of the RFIPM generator, and the lowest achieved by the combination of stator tooth with one notch and ERM poles with a reduction value of about 80% (torque ripple of 5.78%).
