Zusammenfassung:The invention relates to electrical engineering. The electric machine which is the subject of the invention is of the type including, on the one hand, a cylindrical shell 1 inside which are mounted a rotor 4 produced in the form of at least two pole systems 5 which are provided with pole horns and are connected together by a magnetic circuit 7, and a stator 9 including at least two lamination stacks 10, and, on the other hand, an energising system 14, and is characterised in that the energising system 14 is installed outside the shell 1, the latter consisting of magneto-conductive zones 2 alternating axially with non-magnetic zones 3, and in that in each magneto-conductive zone 2 is fixed the corresponding stack 10 of the stator 9. The invention finds its most advantageous applications in fast electric motors for driving turbo compressors, high-pressure pumps for fans, and high-speed wire rolling mills. L'INVENTION CONCERNE L'ELECTROTECHNIQUE.LA MACHINE ELECTRIQUE FAISANT L'OBJET DE L'INVENTION EST DU TYPE COMPORTANT, D'UNE PART, UNE CARCASSE CYLINDRIQUE 1 DANS LAQUELLE SONT MONTES UN ROTOR 4 REALISE SOUS FORME D'AU MOINS DEUX SYSTEMES POLAIRES 5 QUI SONT MUNIS DE CORNES POLAIRES ET RELIES ENTRE EUX PAR UN CIRCUIT MAGNETIQUE 7, ET UN STATOR 9 COMPORTANT AU MOINS DEUX EMPILAGES DE TOLES 10, ET D'AUTRE PART, UN SYSTEME D'EXCITATION 14, ET EST CARACTERISEE EN CE QUE LE SYSTEME D'EXCITATION 14 EST INSTALLE A L'EXTERIEUR DE LA CARCASSE 1, CELLE-CI ETANT CONSTITUEE PAR DES ZONES MAGNETOCONDUCTRICES 2 ALTERNANT AXIALEMENT AVEC DES ZONES AMAGNETIQUES 3, ET EN CE QUE DANS CHAQUE ZONE MAGNETOCONDUCTRICE 2 EST FIXE L'EMPILAGE 10 CORRESPONDANT DU STATOR 9.L'INVENTION TROUVE SES APPLICATIONS LES PLUS AVANTAGEUSES DANS LES MOTEURS ELECTRIQUES RAPIDES D'ENTRAINEMENT DES TURBOCOMPRESSEURS, DES POMPES A HAUTE PRESSION DES VENTILATEURS, DES LAMINOIRS A FIL RAPIDES.
