Abstract

Un bobinage possède une première plaque (55) et une seconde plaque (57) opposée à la première plaque, ainsi que des premier et second manchons (59, 61) solidaires respectivement des première et seconde plaques. Le premier manchon est inséré dans le second manchon. Un manchon diviseur (63) est intégré à la seconde plaque et entoure le second manchon ainsi qu'une première perforation de la seconde plaque. Le manchon diviseur est interposé entre la première plaque et la seconde plaque, entoure le premier manchon et est soudé ou collé à la première plaque. Des premier et second connecteurs (51, 53) sont fixés au bobinage. Une première bobine (43) est fixée autour du manchon diviseur et est connectée aux premiers connecteurs. Une seconde bobine (45) est fixée autour du second manchon et est connectée aux seconds connecteurs par l'intermédiaire de la première perforation. Le manchon diviseur peut être solidaire de la première plaque. Des premier et second bras de couplage (97, 99) peuvent être solidaires de la première plaque et peuvent passer à travers des deuxième et troisième perforations de la seconde plaque, des parties de crêtes de couplage des premier et deuxième bras de couplage étant amenées en contact avec une surface de la seconde plaque. Les premier et deuxième bras de couplage peuvent passer à travers des premier et second canaux de la seconde plaque. Dans ce cas, le manchon diviseur est amené en contact de la première plaque ou de la seconde plaque.
