Abstract

Procédé de contrôle de la position d'un rotor par rapport au stator d'une machine électrique consistant à générer trois impulsions de courant par rapport à l'angle géométrique du rotor dans un enroulement du stator. Les trois impulsions de courant sont une première impulsion de courant, une impulsion de courant décalée par rapport à la première impulsion de courant d'un angle de phase positive prédéfini (ΔΨ1) et une impulsion de courant décalée par rapport à la première impulsion de courant d'un angle de phase négatif prédéfini ΔΨ2. On saisit les trois courants (IE1, IE2, IE3) induits par les trois impulsions de courant dans l'enroulement de rotor, et on vérifie la position du rotor à l'aide de l'amplitude respective de chacun des trois courants induits (IE1, IE2, IE3).A method of controlling the position of a rotor with respect to the stator of an electric machine consisting in generating three current pulses with respect to the geometric angle of the rotor in a winding of the stator. The three current pulses are a first current pulse, a current pulse offset from the first current pulse by a predefined positive phase angle (ΔΨ1), and a current pulse offset from the first current pulse of a predefined negative phase angle ΔΨ2. The three currents (IE1, IE2, IE3) induced by the three current pulses in the rotor winding are entered, and the position of the rotor is checked using the respective amplitude of each of the three induced currents (IE1 , IE2, IE3).
