| Zusammenfassung: | The invention mainly concerns a rotary electric machine, in particular intended for an electric compressor for a motor vehicle, the machine comprising a stator, said stator comprising a body (16) having: - a yoke (28), - a plurality of teeth (27) angularly distributed on an inner periphery of said yoke (28), each tooth (27) having a tooth root (34), and - a plurality of slots (29) each defined by two adjacent teeth (27), characterised in that a ratio between a smallest slot opening (L9) measured between two adjacent tooth roots (34), and an outer diameter of said stator, is of between 5% and 25%, and in particular between 5% and 15%.
L'invention porte principalement sur une machine électrique tournante, notamment destinée à un compresseur électrique pour véhicule automobile, la machine comportant un stator, ledit stator comportant un corps (16) ayant: -une culasse (28), -une pluralité de dents (27) réparties angulairement sur une périphérie interne de ladite culasse (28), chaque dent (27) présentant un pied de dent (34), et -une pluralité d'encoches (29) définies chacune par deux dents (27) adjacentes, caractérisé en ce qu'un ratio entre une plus petite ouverture d'encoche (L9) mesurée entre deux pieds de dent (34) adjacents, et un diamètre externe dudit stator est compris entre, 5% et 25%, notamment entre 5% et 5%. |
