Title
(EN) Stator support, stator, wind driven generator, bearing unit and wind power generation equipment
(ZH) 定子支架、定子、风力发电机、轴承单元和风力发电设备
Abstract
(EN)
The utility model relates to a stator support (27). The utility model relates to a stator (2) for a directly driven wind turbine (1) having an outer rotor, wherein the stator support (27) is supportedon the bearing unit (13) via a fastening element, the fastening element has a central flange (8) that can be connected to the bearing unit (13), and the fastening element expands axially outwards with its radial extent in the direction of the end face of the stator (2) in order to create a cavity (11) radially inside the stator (2). The stator support not only guarantees enough strength of the stator, but also guarantees enough cooling of the stator. In addition, the utility model relates to a stator, a wind driven generator, a bearing unit and wind power generation equipment.
