Title (EN) ROTATING ELECTRICAL MACHINE WITH OPTIMISED ARRANGEMENT
(FR) MACHINE ELECTRIQUE TOURNANTE A CONFIGURATION OPTIMISEE
Abstract:
(EN) The invention relates mainly to a rotating electrical machine of a motor vehicle, comprising a rotor (12) having an axis (X) comprising at least one permanent magnet (20) and a stator (11) surrounding the rotor and comprising a body (24) provided with a plurality of slots (30) and an electrical winding (25), the winding comprising phase windings (26) arranged in the slots, each phase winding being formed by at least one conductor (35). The rotor (12) comprises 3, 4 or 5 pairs of poles. The stator comprises two three-phase systems, each formed by three delta connected phase windings (26). The number of conductors (35) per slot (30) is strictly greater than 2 and each conductor has an active portion (40) inserted in a corresponding slot (30), the active portion with a substantially rectangular section being of a radial length (L2) smaller than or equal to 3.6 mm.
(FR) L'invention porte principalement sur une machine électrique tournante de véhicule automobile comportant un rotor (12) d'axe (X) comportant au moins un aimant permanent (20) et un stator (11) entourant le rotor et comportant un corps (24) doté d'une pluralité d'encoches (30) et un bobinage électrique (25), le bobinage comportant des enroulements de phase (26) disposés dans les encoches, chaque enroulement de phase étant formé par au moins un conducteur (35). Le rotor (12) comporte 3 ou 4 ou 5 paires de pôles. Le stator comporte deux systèmes triphasés formés chacun par trois enroulements de phase (26) couplés en triangle. Le nombre de conducteurs (35) par encoche (30) est strictement supérieur à 2 et chaque conducteur a une portion active (40) insérée dans une encoche (30) correspondante, la portion active de section sensiblement rectangulaire présentant une longueur radiale (L2) inférieure ou égale à 3.6 mm.
