Abstract :
This paper deals with an overhang effect of permanent magnet (PM) in the new type axial flux permanent magnet (AFPM) motor with a double-sided airgap. 3-D electromagnetic finite element method (FEM) is used to calculate the airgap magnetic flux density, back electromagnetic force (EMF) and the cogging torque according to the variation of the overhang angle. The validity of the analysis results is also clarified by comparison between calculated results and measured ones. From the results, we can confirm the overhang effect quantitatively which improves the performance of the AFPM motor
