摘　　要：为了提升转矩性能并降低制造成本,磁阻转矩偏移型模块化电机受到广泛研究。本文在现有转子结构基础上,提出了两种新型磁阻转矩偏移型模块化电机。通过解析公式分析了该种电机的转矩原理,并运用有限元法进行了仿真验证,结果显示,提出的两种新型磁阻转矩偏移型模块化结构相较现有结构可提升输出转矩并降低转矩脉动。与现有结构A相比,本文提出的结构B和结构C分别提升转矩27.8%和17.4%,结构B更能有效地提升转矩,进而提高电机转矩密度和功率密度。In order to improve the torque performance and reduce the manufacture cost,the reluctance-torque-shifting modular machines are widely analyzed.Based on the existing rotor structure,two kinds of new structures of reluctance-torque-shifting modular machines were proposed in this paper.The torque principle of these kinds of machine were analyzed by analytical method and the finite element analysis(FEA) was adopted to validate the principles.It shows that compared with the existing structure,the proposed two reluctance-torque-shifting modular machines can improve the output torque and reduce the torque ripple effectively.Compared with the existing rotor structure model A,the proposed models B and C can improve the average torque by 27.8% and 17.4%,respectively.Clearly,FEA results demonstrate that the proposed model B can improve torque density and power density more effectively.
