Optimization of BLDC Motor for Reduction of Cogging Torque Using Response Surface Methodology

반응표면방법론에 의한 BLDC 전동기의 코깅토크저감을 위한 최적화

This paper presents a optimization procedure by using Response Surface Methodology(RSM) to determine design Parameters for reducing cogging torque in BLDC motor of Electric Power Steering (EPS). RSM is achieved through using the experiment design method in combination with Finite Element Method and well adapted to make analytical model for a complex problem considering a lot of interaction of these parameters. Moreover, Sequential Quadratic Problem (SQP) method is used to solve the resulting of constrained nonlinear optimization problem.
