“…XIAL FLUX PERMANENT MAGNET (AFPM) machines, due to their compact mechanical structure and high power density, are promising in many industrial applications, such as the electric vehicles [1], [2], wind power generation [3] and flywheel energy storage system. However, the rotor misalignment is still remaining as one of the major problems of AFPM machines.…”

This paper proposes an analytical model for the prediction of airgap magnetic field distribution (MFD) for axial flux permanent magnet (AFPM) machine with various types of misalignments. The AFPM machine geometry is first transformed to a polar representation. Consequently, the sub-domain model based on current sheet technique is developed. Then the stator coordinate system is chosen as reference coordinate to consider both static/dynamic angular and axis misalignments. The back electro-magnetic forces and cogging torque are obtained accordingly based on Maxwell's equations. The results show that the proposed approach agrees with the finite element (FE) method. The model is further validated by experiments under healthy, dynamic angular and axis misalignment conditions, which can validate the proposed approach. It turns out that the proposed approach can predict the performance of AFPM machines with types of misalignment quickly and effectively, which is a great significant for the further fault detection.
