Asymmetrical Flux Density Distribution in Stator Teeth of Surface Permanent Magnet Machines

Sala, Giacomo; De Gaetano, Daniele; Degano, Michele; Gerada, Chris

Abstract

This work is showing in detail the flux density behaviour in the stator teeth of a synchronous machine. A 3-phase Surface Permanent Magnet (SPM) motor is considered. These motors are widely employed in applications where high efficiency and power densities are required. This paper aims to analytically demonstrate the asymmetrical distribution of the stator teeth flux density. It is shown that this phenomena is depending on the number of slots per pole and per phase in the machine. Finally, a comparison with Finite Element results is given to validate the effectiveness of the proposed model.
