An electric machine which has an arched stator and a cylindrical rotor fitted inside it and in which the flux flows in the radial direction between the stator and the rotor as in a permanent-magnet radial-flux synchronous electric machine, and in which the stator of the machine consists of stator segments (2), each of which has an independent stator core and winding, and the stator segments are arranged to be physically separate from each other so that the stator consists of stator segments arched according to the radius of the rotor and working electromagnetically independently like a linear machine, each stator segment having a stator core and a winding separate from the other stator segments, and that it comprises an overhead supporting frame structure separate from the stator cores and consisting of several longitudinal ribs (41) and parts (42) between them.
La présente invention a trait à une machine électrique comportant un stator en forme d'arc et un rotor cylindrique monté à l'intérieur de celui-ci et dans lequel le flux circule en direction radiale entre le stator et le rotor comme dans une machine électrique synchrone à aimant permanent et à flux radial, et dans lequel le stator de la machine est constitué de segments de stator (2), dont chacun comprend un noyau et un enroulement de stator indépendants, et lesdits segments de stator sont disposés pour être physiquement séparés les uns des autres de sorte que le stator est constitué de segments de stator en forme d'arc selon le rayon du rotor et fonctionnent de manière électromagnétique indépendante comme une machine linéaire, chaque segment de stator comprenant un noyau et un enroulement de stator séparés des autres segments de stator, et comporte une structure d'encadrement de support surélevée séparée des noyaux de stator et constituée d'une pluralité de nervures (41) et de pièces (42) longitudinales entre elles.
