Defining Design Criteria of an Axial Flux Permanent Magnet Synchronous Generator

Abstract

Axial flux permanent magnet machines using high energy magnets have been increasingly employed for several applications. This work presents a new design procedure for an axial flux permanent magnet synchronous generator (AFPMSG) based on Taguchi experimental design. Interior radius, thickness of the magnet, pole utilization factor and pole number are the analyzed factors. Air-gap magnetic flux density (AGMFD) is chosen as response variable. The aim of the work is to minimize the analyzed factors and maximize the response variable, AGMFD. Simplex algorithm was used to optimize the input variables. According to optimization procedure, interior radius at 39, thickness of the magnet at 8, pole utilization factor at 0.8 and pole number at 8 were chosen as optimized variables. Finite element approach was then used to validate the results. Copyright (C) 2012 Praise Worthy Prize S.r.l. - All rights reserved.
