A stator for an electrical machine includes a back iron including a substantially cylindrical annular structure having an inner surface and an axis. A plurality of supports are fabricated of non-magnetic material, each support extending parallel to the axis of the annular structure along the inner surface of the annular structure, each support including a primary base and at least two primary support members. The primary bases substantially conform to the inner surface of the back iron with the primary support members extending radially inward from the primary base towards the axis of the annular structure. A stator winding is positioned between the at least two primary support members and between the primary base of the support and the axis of the annular structure.
L'invention concerne un stator pour une machine électrique, comprenant un contre-fer incluant une structure annulaire sensiblement cylindrique ayant une surface intérieure et un axe. Une pluralité de supports sont fabriqués à partir d'un matériau non magnétique, chaque support s'étendant parallèlement à l'axe de la structure annulaire le long de la surface intérieure de la structure annulaire, chaque support comprenant une base primaire et au moins deux éléments de support primaires. Les bases primaires se conforment sensiblement à la surface intérieure du contre-fer, les éléments de support primaires s'étendant radialement vers l'intérieur à partir de la base primaire vers l'axe de la structure annulaire. Un enroulement de stator est positionné entre les deux éléments de support primaires, et entre la base primaire du support et l'axe de la structure annulaire.
