摘　　要：由于横向磁场永磁电机具有低转速、高转矩密度的特点,在电机领域被广泛研究,然而由于其结构特点和其它因素的存在,使电机的漏磁大、功率因数偏低,降低了横向磁场永磁电机的性能。提出了一种新颖的敛磁结构,并应用于横向磁场永磁电机模型中,该结构不用增加电流密度或改变气隙大小就可以提高转矩。研究表明该敛磁结构具有很好的敛磁效果,极大地减少了极间漏磁,从而可以提高横向磁场永磁电机的工作性能。TFPM machine has been widely studied in the field of motor with the merits of low speed and large torque density characteristics.However,power factor of TFPM is low because of the TFPM motor structure characteristics and other factors.In this paper,we design a novel TFPM motor,which we believe can have a higher torque without increasing the current density and magnetic air-gap.Section 2 and 3 of the full paper describe the mathematical model and use Maxwell 3D finite element analysis software to obtain simulation results,which,together with their analysis,show preliminarily that the novel TFPM motor structure can indeed improve the performance effectively.
