摘　　要：永磁同步电机(permanent magnet synchronous motor,PMSM)具有结构简单、体积小、效率和功率因数高等优点,在航空航天、军事国防、装备制造、轨道交通、新能源等领域中被广泛应用。但因永磁磁场调节困难,限制了PMSM在宽调速范围领域的进一步应用。为了实现磁场可调,国内外学者做了大量研究工作,提出了多种适合磁场调节的PMSM电磁结构。首先,建立了同步坐标系下PMSM的直轴等效磁路,分析了PMSM磁场调节机理,总结了PMSM磁场调节方法。随后,针对不同典型结构的PMSM分别建立了直轴等效磁路,总结不同磁场调节方法之间的区别和联系。最后,归纳PMSM磁场调节方法,总结形成磁场调节的统一理论,有利于探索磁场可调的PMSM新拓扑结构,推动PMSM磁场调节技术的发展。The permanent magnet synchronous motor(PMSM) is widely used in aerospace,military defense,equipment manufacturing,rail transit,new energy and other fields for their advantages,such as simple structure,small size,high efficiency and power factor.However,it is difficult to adjust the permanent magnet magnetic field,which limits the further application of PMSM to occasions with wide constant power speed range.To adjust the magnetic field of the PMSM,scholars have done a lot of work and put forward a variety of PMSM electromagnetic structure suitable for magnetic field regulation.The d-axis equivalent magnetic circuits(EMC) of the PMSM in the synchronous coordinate system were established,the magnetic field adjustment mechanism of the PMSM were analyzed,and the magnetic field adjustment methods of the PMSM were summarized.The d-axis EMC of the PMSM with different typical structures were established,and the differences and connections between different magnetic field adjustment methods were summarized.Summarizing the magnetic field adjustment methods and the unified theory for PMSM is conducive to exploring new topological structures of the PMSM with wide constant power speed range,and it can promotes the development of PMSM magnetic field adjustment technology as well.
