Title (EN) ROTARY ELECTRICAL MACHINE CLAW ROTOR WITH ENHANCED MAGNETIC PERFORMANCE
(FR) ROTOR A GRIFFES DE MACHINE ELECTRIQUE TOURNANTE A PERFORMANCES MAGNETIQUES AMELIOREES
Abstract:
(EN) The invention mainly relates to a motor vehicle rotary electrical machine rotor comprising at least one magnet wheel including a plurality of claws (29), each claw (29) comprising two side edges (51, 52) extending between a base (53) and a free end (54), said rotor being characterized in that a ratio of the smallest angle (A) expressed in degrees and formed by a side edge (51, 52) of a claw (29) in relation to a straight line (M) perpendicular to said base (53) of the corresponding claw (29) over an intermediate ratio is between 15 and 24, said intermediate ratio being defined by a width (Lb) of said claw (29) over a pole pitch (Tp).
(FR) L'invention porte principalement sur un rotor de machine électrique tournante de véhicule automobile comportant: - au moins une roue polaire comprenant une pluralité de griffes (29), chaque griffe (29) comportant deux bords latéraux (51, 52) s'étendant entre une base (53) et une extrémité libre (54), ledit rotor étant caractérisé en ce qu'un ratio - du plus petit angle (A), exprimé en degrés, que forme un bord latéral (51, 52) d'une griffe (29) par rapport à une droite (M) perpendiculaire à ladite base (53) de la griffe (29) correspondante sur - un ratio intermédiaire - est compris entre 15 et 24, ledit ratio intermédiaire étant défini par une largeur (Lb) de ladite griffe (29) sur un pas polaire (Tp).
