Abstract[English]
A generator rotor for a wind turbine, comprising a cylindrical ring structure defining a radially inner surface and a central hollow portion, and being arranged to rotate around a rotational axis. The cylindrical ring structure comprise a plurality of ring-shaped permanent magnet packages arranged coaxially around the rotational axis, the plurality of permanent magnet packages being adapted to form at least one coolant passage through the cylindrical ring structure. The cylindrical ring structure is adapted to serve as a sump for coolant, such that the sump is defined, at least in part, by the radially inner surface of the cylindrical ring structure, and further comprises at least one coolant passage inlet that extends from the radially inner surface of the cylindrical ring structure to the at least one coolant passage and wherein at least one coolant passage outlet is arranged at one axial end of the cylindrical ring structure.[French]
L'invention concerne un rotor de générateur pour une éolienne, comprenant une structure annulaire cylindrique définissant une surface radialement interne et une partie creuse centrale, et étant agencé pour tourner autour d'un axe de rotation. La structure annulaire cylindrique comprend une pluralité de boîtiers d'aimants permanents annulaires disposés de manière coaxiale autour de l'axe de rotation, la pluralité de boîtiers d'aimants permanents étant conçus pour former au moins un passage de liquide de refroidissement à travers la structure annulaire cylindrique. La structure annulaire cylindrique est conçue pour servir de puisard pour un liquide de refroidissement, de telle sorte que le puisard est formé, au moins en partie, par la surface radialement interne de la structure annulaire cylindrique, et comprend en outre au moins une entrée de passage de liquide de refroidissement qui s'étend de la surface radialement interne de la structure annulaire cylindrique audit au moins un passage de liquide de refroidissement, et au moins une sortie de passage de liquide de refroidissement étant disposée au niveau d'une extrémité axiale de la structure annulaire cylindrique.
