Detection of turn short circuit fault in PMSM variable speed sensorless vector control based on luenberger observer and adaptive Fuzzy Logic Controller [PDF]
The current study describes a novel approach for controlling a Permanent Magnet Synchronous Motor (PMSM) that utilizes intelligent speed sensorless control based on Field-Oriented Control (FOC), by taking inter-turn short-circuit (ITSC) faults into ...

Electromagnetic Vibration and Noise Comparison of Amorphous Metal PMSMs and Silicon Steel PMSMs [PDF]
This paper investigates the differences in the electromagnetic vibration and noise of an amorphous metal (AM) permanent magnet synchronous machines (PMSMs) and silicon steel (SS) PMSMs. The electromagnetic vibration and noise of an AM PMSM and an SS PMSM sharing the same structure and dimensions are calculated under different conditions: 1) only radial

Analysis of the Saliency Ratio Effect on the Output Torque and the System Efficiency in IPM Drives
Permanent magnet synchronous motors (PMSM) can be classified into two groups based on the rotor saliency structure as surface mounted permanent magnet synchronous motors (SPM) and interior mounted permanent magnet synchronous motors (IPM). Saliency ratio
