Analysis of permanent magnet brushless AC motor using two dimensional fourier transform-parseval’s theorem

Abstract

The performance analysis of electrical machines using field solution is necessary for obtaining a closed form analytical solution in terms of machine’s physical parameters. A closed form of solution provides an easy useful tool for the design analysis and optimization of an electromagnetic device. The paper presents a simple numerical-analytical solution for determining the performance characteristics of Surface Mounted Permanent Magnet (SMPM) Brushless AC motor on poleby- pole basis. The Fourier transform applicable to Linear Induction Motor (LIM) is modified and adapted for PMBLAC motor. The performance is obtained in Fourier Space using Parseval’s entity. A good correlation between computed results, experimental and published results validates the approximation used in the analysis. © Springer International Publishing Switzerland 2015.
