Abstract
This paper presents the overhang effects of a novel axial flux permanent magnet (AFPM) machine, which consist of the segmented stator and fractioned slot windings, with one rotor and double stator. In addition, the overhang effect of permanent magnet of the motor has been analyzed quantitatively. The overhang is used to enhance the force density in permanent magnet machine. According to the variation of overhang length, the flux density distribution and torque are quantitatively compared. For these analysis, three dimensional finite element method (3D FEM) has been used in this paper. From the results, the proper overhang length of PM is selected to improve the performance of the AFPM machine.
