Reluctance Network Model of Interior Permanent Magnet Motor with Polar Anisotropic Magnet

Abstract

To establish a practical method for analyzing interior permanent magnet (IPM) motors that have complicated flux distribution, this paper presents a method for deriving an analytical model for the IPM motor with polar anisotropic magnets, based on a reluctance network analysis (RNA). The proposed model can calculate the basic characteristics of the IPM motor with high accuracy and high speed by comparing the calculation results with the FEM and experiment.
