The present invention involves a method and apparatus for canceling the effects of magnetic field noise in a torque sensor by placing three sets of magnetic field sensors around a shaft, the first set of field sensors being placed in the central region of the shaft and the second and third sets of field sensors being placed on the right side and left side of the field sensors placed at the central region, respectively. A torque-induced magnetic field is not cancelled with this arrangement of field sensors but a magnetic near field from a near field source is cancelled.
La présente invention concerne un procédé et un appareil permettant dannuler les effets dun champ magnétique parasite dans un couplemètre par le placement de trois jeux de capteurs de champ magnétique autour dun bras, le premier jeu de capteurs de champ étant placé dans la région centrale du bras et le deuxième et troisième jeu de capteurs de champ étant placés respectivement sur le côté droit et le côté gauche des capteurs de champs placés dans la région centrale. Un champ magnétique induit par un couple nest pas annulé avec cet arrangement de capteurs de champ, mais un champ magnétique proche provenant dune source de champ proche est annulé.
