Abstract

L’invention concerne une machine électrique comprenant un stator et un rotor entrainé en rotation par le stator, le stator comprenant une carcasse dont s’étend au moins une encoche statorique parallèlement à un premier axe de rotation du rotor, la machine électrique comprenant des bobinages d'éléments conducteurs s’étendant concentriquement dans l’au moins une encoche statorique de sorte à former à chaque extrémité du stator, le long du premier axe de rotation du rotor, une tête de bobinage, la machine électrique comprenant au moins une cale d’encoche dans l’encoche statorique de sorte à isoler les éléments conducteurs du bobinage, la machine électrique comprenant au moins un dissipateur de chaleur disposé à l'intérieur d’une encoche statorique entre les éléments conducteurs et/ou dans la cale d’encoche, le dissipateur de chaleur s’étendant depuis la tête de bobinage d’une première extrémité du stator le long du premier axe de rotation du rotor jusqu’à une tête de bobinage d’une deuxième extrémité du stator, le dissipateur de chaleur comprenant un matériau à changement de phase. Figure pour l’abrégé : Fig. 1The invention relates to an electric machine comprising a stator and a rotor rotated by the stator, the stator comprising a carcass of which extends at least one stator notch parallel to a first axis of rotation of the rotor, the electric machine comprising windings of conductive elements extending concentrically in the at least one stator notch so as to form at each end of the stator, along the first axis of rotation of the rotor, a winding head, the electric machine comprising at least one wedge notch in the stator slot so as to insulate the conductive elements of the winding, the electric machine comprising at least one heat sink disposed inside a stator slot between the conductive elements and/or in the slot wedge , the heat sink extending from the winding head of a first end of the stator along the first axis of rotation of the rotor to a winding head of a second end of the stator, the heat sink comprising a phase change material.
