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 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.

Composite-structure rotor

The method includes producing an initial preform on a mandrel by filament winding without generating shrinking, cutting the initial preform to the correct length, placing the assembly provided beforehand with internal drainage device and pressurization device into a female mold, and bringing the preform assembly to a softening temperature and pressurizing the assembly at both ends until it is deformed by a diametrical increase in its dimensions. The method further includes bringing the impregnation resin to polymerization temperature and pressure in order to allow the workpiece to consolidate, its external shape becoming consistent with the internal shape of the mold, opening the mold and removing the workpiece from the mold, and machining the final shapes of the composite workpiece.
