Magnetic Flux Density Distribution of 1.5 kW Permanent Magnet Synchronous Generator by using Response Surface Methodology

Abstract

In this paper, design optimization of 1.5 kW permanent magnet synchronous generator (PMSG) is performed. The aim is to obtain the target magnetic flux density distributions for the responses namely stator-teeth flux density (Tesla), stator-yoke flux density (Tesla), and air-gap flux density (Tesla). For this purpose response surface methodology (RSM) -which is a well-known design of experiments technique -is used for mathematically modelling the relations between the mentioned responses and the design parameters (embrace, outer diameter, and thickness). Maxwell simulation results are used for experimental calculations. Optimization results are also confirmed by using Maxwell program. The results indicate that the RSM is an effective method for design optimization of this type of magnetic devices.
