Abstract

L'invention concerne un micromoteur totalement fermé à faible bruit et à fortes vibrations, comprenant une coque. Un ensemble stator, un ensemble rotor (6) et un ensemble couvercle (2) d'extrémité du moteur sont agencés dans la coque fermée. Une borne électrique (1) de l'ensemble couvercle d'extrémité est découverte depuis une coque en forme de tonneau. Un support de palier (5) et un joint à huile (53) sont par ailleurs agencés dans la direction d'un oscillateur (4) de sorte que le niveau de bruit du moteur peut être réduit et que le rendement de production peut être renforcé. Le support de palier est combiné étroitement à la coque par trois parois convexes (51) agencées à la périphérie de sorte que la séparation du support de palier est empêchée. La teneur en huile lubrifiante contenue peut être économisée par le joint d'huile, réduisant efficacement le bruit.
