Abstract :
This paper deals with an overhang effect of permanent magnet (PM) in the new type axial flux permanent magnet synchronous motor (AFPMSM) with a double-sided air-gap. 3-D electromagnetic finite element method (FEM) is used to calculate the air-gap magnetic flux density, back electromagnetic force (EMF) and the cogging torque according to the variation of the overhang angle. From the results, we can confirm the overhang effect quantitatively which improves the performance of the AFPM motor
