Design and Analysis of Permanent Magnets in a Negative-Salient Permanent Magnet Synchronous Motor [PDF]

IEEE Access, 2020
The Ld of a negative-salient permanent magnet synchronous motor (NSPMSM) is greater than Lq. When a NSPMSM is operating at or below the rated speed, the id is flux-intensifying current, which can improve the flux density of permanent magnets (PM).
