Abstract :
This article shows the reduction of cogging torque in a novel axial flux permanent magnet (AFPM) motor through the various design schemes. 3D finite element method is used for the exact magnetic field analysis. The effects of slot shapes and skewing of slot on the cogging torque and average torque have been investigated in detail. The validity of the analysis results is also clarified by comparison between calculated results and measured ones
