Performance Analysis of a Coreless Axial-Flux Permanent Magnet Machine with Halbach PM Arrangement

Abstract

In order to improve the utilization of PM in electric machine, this paper focus on the performance analysis of a coreless axial-flux PM machine with four types of Halbach PM arrangement. A 3-D FEM model is built and the flux distribution, electromotive force waveforms, output torque, core losses, and efficiency of the four types of Halbach PM arrangement machines have been investigated.
