Title (EN) SENSORLESS ROTOR POSITION DETECTION FOR SWITCHED RELUCTANCE MACHINES HAVING IRREGULAR POLES
(FR) DETECTION DE LA POSITION D'UN ROTOR SANS UTILISER DE DETECTEUR DANS DES MACHINES A RELUCTANCE COMMUTEE PRESENTANT DES POLES IRREGULIERS
Abstract: front page image
(EN)A system for detecting the position of a rotor for a switched reluctance (SR) machine having an irregular pole configuration. The system does not require the use of a conventional sensing device, and provides accurate position information, without disrupting operation of the machine. A voltage ration is used to infer the position of the rotor relative to the stator.
(FR)L'invention concerne un système, permettant de détecter la position d'un rotor dans une machine à réluctance commutée (SR), présentant une configuration de pôles irrégulière. Ce système ne nécessite pas l'utilisation d'un dispositif de détection classique, et fournit des informations de position précises, sans interrompre le fonctionnement de la machine. Un rapport de tension est utilisé pour déduire la position du rotor par rapport à celle du stator.
