Abstract

L'invention relève de l'électrotechnique et des moyens d'automatisation et peut être utilisée en tant que dispositif de réglage de déplacements contrôlés; elle concerne une méthode de commande d'un transducteur magnéto-mécanique, ce dernier comprenant un système magnétique, un noyau N (3) fait d'un matériau magnétostrictif, et un actionneur A (4). La méthode faisant l'objet de la présente invention repose sur les opérations suivantes: on modifie la position du centre d'inertie de A (4) grâce à la création d'un champ magnétique principal dans la zone de N (3); on modifie au moins une fois l'intensité du champ magnétique principal dans des limites comprises entre zéro et une valeur assurant la magnétostriction de la saturation technique du matériau dont est fait N (3) dans la direction du champ magnétique principal; et on maintient dans le temps la position prédéterminée du centre d'inertie de A (4). On crée préalablement dans la zone de N (3) un champ magnétique permanent et auxiliaire dont la valeur d'intensité est inférieure à celle du champ magnétique assurant la saturation technique du matériau de N (3) dans la direction du champ magnétique auxiliaire. Le champ magnétique principal ainsi créé consiste en des impulsions de champ magnétique principal qui ne se chevauchent pas dans le temps, les projections des vecteurs desdites impulsions sur l'axe de N (3), qui coïncide avec la direction de déplacement de A (4), étant orientées dans des directions opposées. On maintient ensuite dans le temps les positions prédéterminées du centre d'inertie de A (4) lorsque la tension du champ magnétique principal est nulle, ceci pendant une période comprise entre les impulsions susmentionnées du champ magnétique principal, et dans les limites de la valeur Δ2L1xmax du changement magnétostrictif résiduel maximal de la dimension linéaire de N (3), ledit changement étant limité par la valeur de l'intensité du champ magnétique auxiliaire.
