Abstract

L'invention concerne des bobines qui peuvent être disposées les unes contre les autres en série le long de leurs axes sans intervalles entre elles. Une bobine (20) comporte un conducteur (2) constitué d'une première partie de conducteur (2A) et d'une seconde partie de conducteur (2B) qui sont sectionnées à une position définie (2C). Le premier conducteur (2A) est enroulé à partir de la partie (2c) partant de l'axe de façon à former une première bobine d'une largeur définie, alors que le second conducteur (2B) est enroulé à partir de la partie (2c) dans le sens opposé de la première bobine (20A) de façon à former une seconde bobine (20B) qui est plus étroite que la largeur définie. Deux extrémités (21, 22) sont apparentes extérieurement pour servir de bornes de raccordement de la bobine. Etant donné que les bornes de raccordement de la bobine sont positionnées extérieurement, elles ne doivent pas provoquer d'interférence lorsqu'un certain nombre de bobines (20) sont disposées les unes contre les autres selon le sens axial.
