ROTARY ELECTRIC GENERATOR STATOR, ROTARY ELECTRIC GENERATOR COMPRISING SAID STATOR AND WIND TURBINE INCORPORATING SAID ROTARY ELECTRIC GENERATOR

摘要

It allows a more complete cooling of the generator, comprising: a magnetic core with a crown (3) from the periphery whereof emerge teeth (4) which have coiled windings (5); an external cooling circuit (9) to carry a coolant fluid; at least one through-hole (12) running along the interior of each tooth (4), and at least one first duct (13), to connect the through-hole (12) with the external cooling circuit (9) and with the through-hole (12) so that it allows the passage of the coolant fluid, the first duct (13, 16) being interposed between one end (7, 8) of the tooth (4) and the winding (5).

主权项

1. A stator of a rotary electric generator, the stator comprising:
a magnetic endowed with a magnetic crown which in turn is endowed with at least one tooth having a first end and a second end opposite the first end; a winding wound around the at least one tooth; an external cooling circuit configured so as to carry a coolant fluid to refrigerate the stator; and at least one through-hole located in the at least one tooth, which longitudinally runs through the tooth between the ends of the tooth; the stator further comprising at least one first duct situated in connection with the external cooling circuit and with the through-hole so as to allow the passage of the coolant fluid, the first duct being interposed between the first end of the tooth and the winding.
