            Abstract : 
This paper presents the study 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, analytical method and two dimensional finite element method were utilized to analysis the multi-slice model. Three dimensional finite element method (3D FEM) has been used to study the overhang effect.
