Title: Study on torque of claw pole machine with outer PM rotor
Abstract: In order to research special issues of torque density and cogging torque for a novel claw pole machine with outer permanent magnet rotor(CPMPM) and special structure,on the basis of analyzing it's structure,material,characteristics and operating mechanism,the formula of torque density and cogging torque is derived,the reason of torque density and cogging torque being higher than those of conventional machine was analyzed in theory.By means of finite element analysis(FEA) software,the three-dimensional(3D) electromagnetic field analysis was made for this kind of machine.The torque density and cogging torque were computed by analysis method of field,while the effect of output torque was analyzed under the condition of different pole number.Finally,the formula derivation and simulation results are verified by the prototype experiments.The theoretical analysis,simulation and experiment results show that this kind of machine has characteristics of higher torque density than those of conventional electric machines and has unique characteristics of cogging torque.
