Abstract

Moteur comportant un refroidissement spécial par une roue à ailettes. Le moteur électrique 1 possède un carter 2 avec des nervures de refroidissement 3. Le stator comprend des enroulements 4, le rotor est porté par les paliers 5, 6. Le bout d'arbre 9 est dans une atmosphère 19 à température élevée. Une plaque de guidage 10 est placée entre le plateau palier 18 et la platine avant 11. Des ouvertures d'entrée et de sortie d'écoulement 13, 14 se trouvent de part et d'autre de la plaque 10. La roue à ailettes 15 possède des ouvertures de passage d'air 17 entre son moyeu 16 et l'arbre 9.Motor with special cooling by a paddle wheel. The electric motor 1 has a casing 2 with cooling ribs 3. The stator comprises windings 4, the rotor is carried by the bearings 5, 6. The shaft end 9 is in an atmosphere 19 at high temperature. A guide plate 10 is placed between the bearing plate 18 and the front plate 11. Flow inlet and outlet openings 13, 14 are located on either side of the plate 10. The impeller 15 has air passage openings 17 between its hub 16 and the shaft 9.
