Abstract: A three-dimensional magnet structure (6) made up of a plurality of individual magnets (4), the magnet structure (6) having a thickness that forms its smallest dimension, the magnet structure (6) incorporating at least one mesh (5a) exhibiting mesh cells each one delimiting a housing (5) for a respective individual magnet (4), each housing (5) having internal dimensions just large enough to allow an individual magnet (4) to be inserted into it, the mesh cells being made from a fibre-reinforced insulating material, characterized in that a space is left between the housing (5) and the individual magnet (4), which space is filled with a fibre-reinforced resin, the magnet structure (6) comprising a non-conducting composite layer coating the individual magnets (4) and the mesh structure (5a).

Abstract: A magnet structure comprising a plurality of individual magnets in the form of an elongate block (4) having a length (4a) extending beyond the thickness of the magnet structure. The elongate block (4) is cylindrical or polyhedral in shape with at least one flat longitudinal face (4b) orientated towards a working surface of the magnet structure, the elongate block (4) having a line of magnetisation extending along its length. The individual magnets (4) being positioned at a distance from each other in the magnet structure in order to be electrically isolated from each other, the length (4a) of each block (4) being greater than the diameter of the flat longitudinal face (4b) for a cylindrical block (4) or with a larger diagonal (4c) connecting two apexes of said longitudinal face (4b) for a block (4) in the form of a polyhedron.

Abstract: This invention relates to a stator for an axial flux electromagnetic machine, with the stator forming a ring (1) having two substantially circular faces (1a, 1b) connected by a thickness comprising windings (3) regularly distributed in the ring (1). Each winding (3) is carried by a unit portion (4) having a core (5) around which the winding (3) is wound. The unit portions (4) are arranged concentrically edge-to-edge with respect to one another and have securing means (12, 12a, 14) with a support member (6) which is part or not of a casing housing the ring (1) carried either by axial and lateral faces of each unit portion (4) edge-to-edge or by at least one upper or lower face of with each unit portion being part of a substantially circular face.
