Abstract

The present invention seeks to reduce acoustic emissions from a synchronous generator of a wind turbine. The invention provides a synchronous-generator stator, comprising a stator ring (300), a stator core (400), a circumferential gap (310) between the stator ring (300) and the stator core (400), and a plurality of decoupling units (500) in the gap (310), wherein the decoupling unit (500) has a first plate (510), which is matched to a contour of the stator core (400), and has a second plate (530), which is matched to the contour of the stator ring (300), wherein a mat (520), having a cavity and an inlet valve (540), is provided between the first and the second plate (510, 530) such that the decoupling units (500) reduce the transmission of vibrations or structure-borne noise from the stator core (400) to the stator ring (300).
