Zusammenfassung:	The invention mainly relates to a motor vehicle starter stator (3) comprising: - a cylinder head (4); and - a set of permanent magnets (5) mounted against an inner face (41) of said cylinder head (4). Each permanent magnet (5) from said set is magnetically oriented in a radial manner. Said stator is characterized in that the mean remanence of said permanent magnet set (5) is within a range of between 0.73 and 0.87 Tesla, in particular between 0.78 and 0.83 Tesla, and preferably between 0.79 and 0.81 Tesla. L'invention porte principalement sur un stator (3) de démarreur de véhicule automobile comportant : - une culasse (4), - un ensemble d'aimants permanents (5) montés contre une face interne (41 ) de ladite culasse (4), chacun des aimants permanents (5) dudit ensemble étant magnétiquement orienté radialement, caractérisé en ce que la rémanence moyenne dudit ensemble d'aimants permanents (5) est comprise dans une plage située entre 0,73 et 0,87 Tesla, notamment entre 0,78 et 0,83 Tesla et de préférence entre 0,79 et 0,81 Tesla.
