Rotor of an electrical generator for aeolian application with cooling flows in at least one of the coil heads

A rotor of an electrical generator for Aeolian application with cooling flows in at least one of the coil heads, comprising:

• an axle;
• at least one set of stacked magnetic plates;
• at least an alternating current polyphase winding that comprises at least an upper layer and a lower layer;
• at least a bandage surrounding the outside of the polyphase winding on at least one coil head;
• and,
• at least one insulator sandwiched between the upper and lower winding layers;
• at least on one coil head, the bandage and the sandwiched insulator being divided into at least two independent parts separated by a determined axial distance, in order to provide at least one radial path enabling a cooling air flow between, the respective parts of the bandage and the sandwiched insulator.
