Beschreibung
Zusammenfassung:	The invention mainly concerns a stator (9) of a rotary electric machine, in particular intended for an electric compressor for a motor vehicle, said stator (9) comprising a body (16) having: -a yoke (28), -a plurality of teeth (27) angularly distributed on an inner periphery of said yoke (28), -a winding (17) comprising a plurality of coils (50), each coil (50) being formed by a wire (51) wound around a tooth (27), characterised in that a ratio between a diameter of a conductive portion of said wire (51) and an inner diameter of said stator (9) is of between 3% and 10%. L'invention porte principalement sur un stator (9) de machine électrique tournante, notamment destinée à un compresseur électrique pour véhicule automobile, ledit stator (9) comportant un corps (16) ayant : -une culasse (28), -une pluralité de dents (27) réparties angulairement sur une périphérie interne de ladite culasse (28), -un bobinage (17) comportant une pluralité de bobines (50), chaque bobine (50) étant formée par un fil (51) enroulé autour d'une dent (27), caractérisé en ce qu'un ratio entre un diamètre d'une portion conductrice dudit fil (51) et un diamètre interne dudit stator (9), est compris entre 3et 10%.
