Abstract

L'INVENTION SE RAPPORTE A UN ACCOUPLEMENT ELECTROMAGNETIQUE DU TYPE COMPRENANT UN NOYAU MAGNETIQUE STATIONNAIRE, UN ROTOR QUADRIPOLAIRE ET UNE ARMATURE TOURNANTE. LES FACES POLAIRES INTERMEDIAIRES ET LA FACE POLAIRE INTERNE DU ROTOR SONT DEFINIES SUR UNE SURFACE AXIALE D'UN PREMIER ANNEAU EN MATERIAU MAGNETIQUE, ET LA FACE POLAIRE EXTERNE EST DEFINIE SUR UNE SURFACE AXIALE D'UN SECOND ANNEAU EN MATERIAU MAGNETIQUE. DES FENTES CIRCONFERENTIELLES TRAVERSENT LE PREMIER ANNEAU POUR SEPARER LA FACE POLAIRE INTERNE DES FACES INTERMEDIAIRES, ET LES DEUX ANNEAUX SONT RELIES PAR DES BRAS REALISES D'UN SEUL TENANT AVEC LE PREMIER ANNEAU ET FIXES PAR BRASURE AU SECOND ANNEAU. DES FENTES CIRCONFERENTIELLES FORMEES DANS L'ARMATURE DELIMITENT SUR LE PREMIER ANNEAU LES FACES POLAIRES INTERMEDIAIRES. APPLICATION A LA REALISATION D'ACCOUPLEMENTS PEU COUTEUX ET DONT LA CAPACITE DE COUPLAGE EST ELEVEE.THE INVENTION RELATES TO AN ELECTROMAGNETIC COUPLING OF THE TYPE INCLUDING A STATIONARY MAGNETIC CORE, A QUADRIPOLAR ROTOR AND A ROTATING ARMATURE. THE INTERMEDIATE POLAR FACES AND THE INTERNAL POLAR FACE OF THE ROTOR ARE DEFINED ON AN AXIAL SURFACE OF A FIRST RING OF MAGNETIC MATERIAL, AND THE EXTERNAL POLAR FACE IS DEFINED ON AN AXIAL SURFACE OF A SECOND RING OF MAGNETIC MATERIAL. CIRCUMFERENTIAL SLOTS CROSS THE FIRST RING TO SEPARATE THE INTERNAL POLAR FACE FROM THE INTERMEDIATE SIDES, AND THE TWO RINGS ARE CONNECTED BY ARMS MADE OF A SINGLE HOLD WITH THE FIRST RING AND FIXED BY BRAZING TO THE SECOND RING. CIRCUMFERENTIAL SLOTS SHAPED IN THE FRAMEWORK DELIMIT THE INTERMEDIATE POLAR FACES ON THE FIRST RING. APPLICATION TO THE REALIZATION OF LOW COST COUPLINGS WITH HIGH COUPLING CAPACITY.
