Contribution à l'étude des machines électriques en présence de défaut entre-spires : Modélisation - Réduction du courant de défaut

B. Vaseghi
TL;DR: In this article, a methode basee sur la segmentation des aimants sous un pole qui n'est en fait qu'une demultiplication du nombre de poles au rotor without modification du bobinage statorique is proposede est utilise for reduire le courant de defaut.

Speed Sensor-Less Predictive Torque Control for Five-Phase Induction Motor Drive Using Synthetic Voltage Vectors

TL;DR: In this paper, a sensorless predictive torque control (PTC) for a five-phase induction motor (IM) drive without speed sensor [sensorless PTC-S] is presented, where the adaptive full observer is incorporated to estimate the stator flux, stator resistance and rotor speed.

Adaptive Estimation of Speed and Rotor Time Constant for the Vector Controlled Induction Motor Drive Using Reactive Power

TL;DR: In this article, a model reference adaptive system (MRAS) based technique for the estimation of speed and rotor time constant for induction motor drive is presented, which uses both the instantaneous and steady state reactive power to formulate the error signal.
