摘　　要：反凸极永磁同步电机的直轴电感大于交轴电感,与传统正凸极永磁同步电机相比,具有恒功率调速范围宽、过载能力强、空载反电动势低和永磁体不易退磁等特点,在数控机床主轴系统和电动车驱动系统等调速范围要求高的场合中具有广泛应用前景。文中针对反凸极永磁同步电机本体结构和电流控制技术发展现状两方面进行综述。总结反凸极永磁同步电机的特点;分析国内外径向磁场和轴向磁场反凸极电机的结构特点和电磁特性,归纳出其共性规律和个性差别;阐述目前该类电机的电流控制技术;对该类电机及其控制的主要研究方向进行展望。The Ld of the Negative-salient Permanent Magnet Synchronous Motors(NSPMSM) is greater than Lq.Compared with Positive-saliency Permanent Magnet Synchronous Motors(PSPMSM), NSPMSM has broad application prospect in spindle system of number control machine tool and drive system of electric vehicle for its advantages, such as wide constant-power speed range, high overload capacity, low no-load back-EMF and preventing permanent magnet demagnetization. In this paper, we reviewed the development of NSPMSM structure and its current control technology respectively. Firstly, we summarize the features of NSPMSM. Secondly, we analyze the structural characteristics and electromagnetic characteristics for the NSPMSM at the site of radial magnetic field and axial magnetic field, and then summarize their commonality and personality differences.Moreover, we expound the current control technology of this kind of motors. Finally, the development prospect of NSPMSM are stated in the ontology and its control aspects.
