Abstract
MOTEURS PAS A PAS ET PLUS PARTICULIEREMENT MOTEURS PAS A PAS PREVUS POUR LES MONTRES ELECTRONIQUES. DANS LE CAS D'UNE CONSTRUCTION COMPORTANT DEUX POLES LIES A UN NOYAU PORTANT UNE BOBINE ALLONGEE, LES POLES SONT LIES L'UN A L'AUTRE ENTRE LEURS BECS PAR DES ELEMENTS INTERCALAIRES EN UN MATERIAU DONT LA PERMEABIBILITE MAGNETIQUE EST AUSSI VOISINE QUE POSSIBLE DE 1. LE STATOR MONOBLOC PEUT ETRE FORME PAR DECOUPAGE EN UNE OPERATION DANS UNE BANDE COMPOSITE, CE QUI SIMPLIFIE CONSIDERABLEMENT LE PROBLEME DU POSITIONNEMENT DES POLES DU STATOR PAR RAPPORT A LA PLATINE ET AU ROTOR. L'INVENTION COMPORTE EGALEMENT DES MOYENS PERMETTANT DE FABRIQUER LES STATORS MONOBLOCS RATIONNELLEMENT ET NOTAMMENT UN PROCEDE CONSISTANT A LAMINER ENSEMBLE DEUX LAMES EN METAL FERRO-MAGNETIQUE ET UN FILET INTERCALAIRE EN METAL AMAGNETIQUE, CES ELEMENTS ETANT LIES PAR LEUR TRANCHE DE FACON A FORMER UNE BANDE COMPOSITE DANS LAQUELLE LES STATORS SONT DECOUPES.
