Abstract
A stator assembly, an electric machine and a wind turbine having the stator assembly are provided. The stator assembly includes a stator iron core, a stator bracket supporting the stator iron core, and an air flow conveyer configured to convey a first cold air flow along the radial direction of the stator iron core to a radial side surface of the stator iron core opposite to an air gap side. The embodiment of the present disclosure enables two radial sides of the stator to be cooled at the same time. Thereby, the expansion and deformation of the stator iron core are reduced, the air gap is prevented from being narrowed, magnetic poles are protected from being baked by the high temperature of the stator, and the service life of the electric machine is prolonged.
