Calculation of 3D Airgap Magnetic Field Distribution of an Axial Flux Permanent Magnet Motor

Article Preview

Abstract:

With the slice tool in finite element software Magnet, 3D magnetic field distribution in airgap of an axial flux permanent magnet motor (AFPMM) is studied. Then analytical method, finite element method and average radius method are used to calculate the airgap magnetic flux of per pole respectively. The results which are gotten through these methods are approximate and can reflect per pole magnetic flux of AFPMM generally. The above research has achieved anticipated effect and provided a basis for the calculation of AFPMM airgap magnetic field.
