description The invention mainly concerns a stator (9) of a rotary electric machine, in particular intended for an electric compressor for a motor vehicle, the stator (9) comprising: - a yoke (28), - a plurality of teeth (27) angularly distributed on an inner periphery of said yoke (28), - a plurality of slots (29) each defined by two adjacent teeth (27), - a winding (17) comprising a plurality of coils (50), each coil (50) being formed by a wire (51) wound around a tooth, characterised in that a ratio between a diameter of a conductive portion of said non-enamelled wire (51), expressed in mm, and a number of turns of each coil (50) is of between 5% and 25%, and in particular between 10% and 20%.
