Abstract

MOTEUR ELECTRIQUE PAS A PAS A AIMANTS PERMANENTS COMPORTANT UN STATOR MUNI D'UNE PLURALITE D'ENCOCHES ET D'UN BOBINAGE PROPRE A ENGENDRER UNE SUCCESSION ALTERNEE DE POLES NORD ET SUD. LES BOBINAGES SONT CONSTITUES PAR N ENROULEMENTS INDEPENDANTS TRAVERSANT RESPECTIVEMENT UNE ENCOCHE 106 SUR N; LES SENS DE CIRCULATION DES COURANTS DANS LES ENROULEMENTS SONT DETERMINES SELON UNE SEQUENCE PREETABLIE POUR ENGENDRER 2P POLES TOURNANT AVEC UN PAS PREDETERMINE. EN OUTRE LE ROTOR COMPORTE 2P AIMANTS PERMANENTS 112. APPLICATION AUX MOTEURS A GRANDS NOMBRES DE PAS D'AVANCEMENT.ELECTRIC STEP BY STEP MOTOR WITH PERMANENT MAGNETS INCLUDING A STATOR EQUIPPED WITH A PLURALITY OF NOTCHES AND A CLEAN WINDING TO GENERATE AN ALTERNATE SUCCESSION OF NORTH AND SOUTH POLES. THE WINDINGS ARE CONSTITUTED BY N INDEPENDENT WINDINGS RESPECTIVELY CROSSING A NOTCH 106 ON N; THE DIRECTIONS OF CIRCULATION OF CURRENTS IN THE WINDINGS ARE DETERMINED ACCORDING TO A PRE-ESTABLISHED SEQUENCE TO GENERATE 2P POLES ROTATING WITH A PREDETERMINED STEP. IN ADDITION THE ROTOR INCLUDES 2P PERMANENT MAGNETS 112. APPLICATION TO MOTORS WITH LARGE NUMBERS OF FORWARD STEPS.
