Abstract

TRANSDUCTEUR ELECTROMAGNETIQUE DESTINE AU MECANISME D'ENTRAINEMENT D'UNE HORLOGE ELECTRIQUE. IL COMPORTE UN ROTOR 4 A AIMANTATION PERMANENTE ET UN ENSEMBLE DE STATOR COMPORTANT UNE BOBINE EXCITATRICE 2. CET ENSEMBLE DE STATOR COMPREND DEUX PARTIES 1A, 1B GEOMETRIQUEMENT IDENTIQUES. LA LIAISON MAGNETIQUE DES DEUX ELEMENTS 1A, 1B EST REALISEE PAR UN CHEVAUCHEMENT 10 SUR UNE GRANDE SURFACE DE CEUX-CI. LES BRANCHES 5A, 5B DES DEUX ELEMENTS 1A, 1B COMPORTENT DANS LA ZONE DE CHEVAUCHEMENT UNE OU PLUSIEURS COUDURES PARALLELES EN DEHORS DU PLAN DES ELEMENTS DE STATOR. APPLICATIONS: NOTAMMENT AUX HORLOGES A QUARTZ.
