A rotor of a wind turbine large-diameter rotary electric machine has a hub configured to rotate about an axis of rotation; a tubular structure extending about the hub and supporting a plurality of active segments arranged about the axis of rotation; and a radial structure configured to connect the hub to the tubular structure, which is divided into a plurality of sectors connectable selectively to the radial structure.

Large-diameter rotary electric machine rotor, and rotary electric machine

The invention refers to a direct drive electric generator for a wind turbine provided with rotor salient poles and a ladder-like cryostat for housing superconductive coils and keeping them at a cryogenic temperature while the interior of the cryostat is kept free of coolant. The invention achieves optimal thermal insulation of the coils without the need of a continuous re-filling of the cryostat and ensuring a good distribution of the magnetic field avoiding the use of expensive materials.
