Composite-structure rotor for axial flow electrical machines comprising at least one stator and a rotor rigidly connected to a shaft to be rotated, in the shape of a disc and comprising a plurality of permanent magnets supported by a support made of a composite material rigidly connected to the shaft to be driven and constituted by a reinforced fibre matrix, The rotor comprises distributed attachment means for the radial elements and segments, which connect the elements in pairs, forming recesses, and which comprise at least one strap resulting from the winding of continuous unidirectional fibres passing between th Composite-structure rotor for axial flow electrical machines comprising at least one stator and a rotor rigidly connected to a shaft to be rotated, in the shape of a disc and comprising a plurality of permanent magnets supported by a support made of a composite material rigidly connected to the shaft to be driven and constituted by a reinforced fibre matrix. The rotor comprises distributed attachment means for the radial elements and segments, which connect the elements in pairs, forming recesses, and which comprise at least one strap resulting from the winding of continuous unidirectional fibres passing between the magnets, on the outside edge thereof, as well as on each of the attachment means, in order to form a collective retention of the magnets.
