Abstract

STRUCTURE POLAIRE D'UN MOTEUR PAS A PAS A RELUCTANCE VARIABLE POUR L'AUTOMATISATION DE SON PROCEDE DE FABRICATION. LE MOTEUR PAS A PAS COMPREND PLUSIEURS POLES POURVUS DE PLUSIEURS DISCONTINUITES MAGNETIQUES DANS PLUSIEURS FACES POLAIRES D'UNE STRUCTURE POLAIRE. LE PROCEDE DE FABRICATION CONSISTE A POURVOIR UNE PREMIERE PARTIE DE LA STRUCTURE POLAIRE D'ENROULEMENTS 20 BOBINES AUTOUR D'ELEMENTS POLAIRES 16 PREVUS SUR LA STRUCTURE ET A COLLER UNE AUTRE PARTIE DE LA STRUCTURE SUR LA PREMIERE PARTIE DE CELLE-CI. APPLICATION A LA FABRICATION DES MOTEURS PAS A PAS.POLAR STRUCTURE OF A STEP MOTOR WITH VARIABLE RELUCTANCE FOR THE AUTOMATION OF ITS MANUFACTURING PROCESS. THE STEPPER MOTOR INCLUDES SEVERAL POLES PROVIDED WITH SEVERAL MAGNETIC DISCONTINUITS IN SEVERAL POLAR FACES OF A POLAR STRUCTURE. THE MANUFACTURING PROCESS CONSISTS OF PROVIDING A FIRST PART OF THE POLAR STRUCTURE WITH 20 COILS WINDINGS AROUND POLAR ELEMENTS 16 PROVIDED ON THE STRUCTURE AND IN GLUING ANOTHER PART OF THE STRUCTURE ON THE FIRST PART OF IT. APPLICATION TO THE MANUFACTURE OF STEP MOTORS.
