Analysis and Performance Evaluation of an Axial-Field Brushless PM Machine Utilising Soft Magnetic Composites

Abstract

One of the major research activities in electric machines involves the use of alternative magnetic materials. Soft magnetic composites (SMC) offer the advantages of 3D magnetic flux paths and low-cost manufacturing. This paper examines the analysis and modelling of a prototype axial-field permanent magnet machine which uses SMC. Measured parameters and performance with an inverter is compared to 3D finite-element simulations.
