Analysis of Torque Pulsation considering Interior Permanent Magnet Rotor Rib Shape using Response Surface Methodology

摘要

This paper deals with the analysis of torque pulsation considering interior permanent magnet rotor rib shape using response surface methodology (RSM). We determine the initial interior permanent magnet synchronous motors (IPMSM) with 6-pole NdFeB magnets rotor and 9-slot stator. We select 3 points in rotor rib and change these points using RSM. These models are analyzed by finite element method (FEM). Using these results, we find optimal model, and analyze effect of each parameter. Finally, optimal model compare with initial model.
