Abstract

Capteurs magnétiques disposés chacun pour faire face à chacun de chemins de courant pour chacun d’enroulements avec 2n phases (n est un multiple de trois) dans une machine tournante CA, et lorsque chacune d’une composante CC et d’une composante CA dans un courant de somme d’axe d et d’un courant de somme d’axe q obtenus en effectuant une transformation dq dans un système de coordonnées à deux axes sur 2n courants de détection dans l’hypothèse où toutes les amplitudes de courant des enroulements sont les mêmes est représentée collectivement avec chacun de termes exprimés par des fonctions sinus avec des phases différentes les unes des autres, chacun des chemins de courant dans chacune de 2n positions d’agencement de chemin de courant est agencé pour avoir une relation positionnelle où des composantes d’erreur sont réduites par annulation parmi des coefficients compris dans au moins l’un des termes ou par annulation parmi des valeurs des termes.
