ABSTRACT:
An apparatus (10) for supporting a winding (7) on a stator (1), in particular on a generator stator in a power station. The winding (7) has an end winding (9) which is supported axially on the core (2) of the stator (1) via winding supports (11) of the supporting apparatus (10). The winding supports (11) are supported on the end winding (9) via a stressing device (22), at right angles to an envelope surface (21). In order to improve the axial position between the winding support (11) and the end winding (9) during operation of the stator (1), a coupling device (23) is provided which allows relative movements between the end winding (9) and the winding support (11) in the circumferential direction and at right angles to the envelope surface (21), and prevents such relative movements in an envelope line direction (30).
