摘　　要：通过对两种12/10混合励磁开关磁链(HESFPM)电机的比较,研究了不同定子结构混合励磁电机的调磁性能。第一种混合励磁开关磁链电机(HESFPM-1)选择直流励磁绕组来代替部分永磁体,而第二种电机(HESFPM-2)将直流励磁绕组放置在传统的开关磁链电机的定子轭部。HESFPM-2电机的直流励磁绕组槽面积更大,该电机具有更好的弱磁和增磁能力。在电机设计中,HESFPM-2电机的槽面积比具有较宽的范围,因此电机设计更加灵活。比较了两种混合励磁开关磁链电机在不同永磁体长度、宽度以及定子齿宽下,电机的转矩和调磁性能。通过有限元分析和实验样机对HESFPM-2电机的调磁性能进行了验证,结果表明,有限元仿真结果与实验结果有较好的一致性。Two types of 12/10 hybrid excited switching flux permanent magnet( HESFPM) machines were designed and compared to investigate the flux adjustment capability. In the first HESFPM machine( HESFPM-1),partial permanent magnets were replaced by DC field windings,while in the other one( HESFPM-2) the DC field windings were placed outside the conventional switching flux PM machine. The HESFPM-2 exhibits much larger slot area for DC field windings,which indicates higher flux enhancing or weakening capability. The HESFPM-1 machine is more sensitive to the change of the slot area of the machine. In addition,the comparison of flux adjustment capability between the HESFPM machines was also carried out at different length and width of PM and stator tooth width. 2 D finite element analysis and experiments on the prototype of HESFPM machine were presented for verification,the finite element simulation results were in good agreement with the experimental results.
