Abstract

La présente invention concerne une machine électrique (1) supraconductrice à flux axial comprenant un inducteur (6, 7) et un induit (5), l’inducteur (6, 7) comprenant : - des pastilles supraconductrices (7) mobiles en rotation autour d’un axe (X) de la machine électrique (1) ; et - une bobine supraconductrice (6), centrée sur l’axe (X) et s’étendant radialement à l’extérieur des pastilles supraconductrices (7), la bobine supraconductrice (6) étant configurée pour générer un champ magnétique ; la machine électrique (1) étant caractérisée en ce qu’elle comprend en outre une barrière de flux (12) réalisée dans un matériau supraconducteur qui s’étend entre les pastilles supraconductrices (7) et la bobine supraconductrice (6), ladite barrière de flux (12) étant fixée sur une paroi circonférentielle (7a) des pastilles supraconductrices (7) de sorte à être solidaire en mouvement des pastilles supraconductrices (7). Figure pour l’abrégé : Fig. 1The present invention relates to an axial flux superconducting electrical machine (1) comprising an inductor (6, 7) and an armature (5), the inductor (6, 7) comprising: - superconducting pellets (7) movable in rotation around an axis (X) of the electric machine (1); and - a superconducting coil (6), centered on the axis (X) and extending radially outside the superconducting pads (7), the superconducting coil (6) being configured to generate a magnetic field; the electric machine (1) being characterized in that it further comprises a flux barrier (12) made of a superconducting material which extends between the superconducting pellets (7) and the superconducting coil (6), said barrier of flux (12) being fixed on a circumferential wall (7a) of the superconducting pellets (7) so as to be integral in movement with the superconducting pellets (7).
