Cogging Torque Analysis of Novel Dual-Rotor Axial Field Flux-Switching Permanent Magnet Machine
The cogging torque of a novel dual-rotor axial field flux-switching permanent magnet (DRAFFSPM) machine is investigated in this paper.The analytical equation of the DRAFFSPM machine is deduced.Based on 3D finite element method,the influences of the design parameters,such as stator tooth width,stator magnet width,stator axial length,rotor pole width,rotor pole shape,and rotor axial length,etc,on the cogging torque are analyzed.The H-shaped stator tooth with slot chamfer is proposed and the slot opening width and chamfer thickness are optimized to reduce the cogging torque.The results show that the cogging torque is the minimum when the stator tooth width equal to 8°mech.and the stator magnet width equals to 7.5° mech.The cogging torque can be reduced by ~64% when the fan-shaped rotor pole width is 1.6 times that of the original design.The cogging torque can be reduced by ~80% when the chamfer is added in the stator slot.
