摘要：
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. © 2019 Chin. Soc. for Elec.
