Abstract
In this paper the influence of magnetization pattern on the magnetic field features and characteristics in a surface mounted permanent magnet motor is analysed. A comparative analysis of performance characteristics for a conventional surface PM motor with Halbach array topologies is presented. The study is based on FEM field computations that enable the visibility of the magnetic properties and characteristics. The emphasis is put on electromagnetic field distribution, magnetic flux per pole profile and components of the flux density in the air gap.
