A State Observer For The Permanent-Magnet Synchronous Motor [PDF]
An identity state observer for the permanent-magnet synchronous motor is derived which reconstructs the electrical and mechanical states of the motor from current and voltage measurements. The observer operates in the rotor frame and estimates direct and quadrature stator currents, rotor velocity, and rotor position.

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