A rotary machine for a wind turbine includes: a rotor; and a casing for housing the rotor and supported by a base portion so as to constitute a stator of the rotary machine. At least a part of the casing is configured to be rotatable together with the rotor while permitting relative rotation with respect to the base portion when a rotational force equal to or greater than a threshold torque value is applied to the rotor. L'invention concerne une machine rotative d'une éolienne. Ladite machine rotative comprend : un rotor; et un carter pour loger le rotor et supporté par une partie de base de façon à constituer un stator de la machine rotative. Au moins une partie du carter est conçue pour pouvoir tourner conjointement avec le rotor tout en permettant une rotation relative par rapport à la partie de base lorsqu'une force de rotation égale ou supérieure à une valeur de couple seuil est appliquée au rotor.
