Oskar Wallmark, Auteur ; Kjellqvist, Peter, Auteur |This paper presents an analysis of a concentrated air-gap winding concept intended for low-cost, high-speed applications where the reduced winding construction cost can motivate its use. Expressions for magnet flux linkage, torque, winding induc[...]

Oskar Wallmark, Auteur ; Lennart Harnefors, Auteur ; Carlson, Ola, Auteur |This paper proposes control algorithms for a fault-tolerant permanent-magnet synchronous motor (PMSM) drive. In order to improve the reliability of the drive, an algorithm for achieving a sensorless control that operates properly also in fault m[...]

Oskar Wallmark, Auteur ; Lennart Harnefors, Auteur |This paper considers speed and position estimation of salient permanent-magnet synchronous machines (PMSMs). An estimator of phase-locked loop (PLL) type is considered. Signal injection techniques are used in the zero-speed and low-speed regions[...]
