Abstract
The present invention concerns a wind power installation having a support structure for the stator of a ring generator, wherein the support structure has a plurality of support arms. The object of the present invention is to reduce the sound emissions emanating from a wind power installation as set forth in the classifying portion of the claim. A wind power installation having a generator, preferably a ring generator, comprising a rotor and a stator which has a mounting means for stator windings, wherein the stator is held by a support structure which has a plurality of support arms and wherein an odd number of support arms are provided and/or the support arms are irregularly spaced.
Claims3
A wind power installation having a generator, preferably a ring generator, comprising a rotor and a stator which has a mounting means for stator windings, wherein the stator is held by a support structure which has a plurality of support arms and wherein an odd number of support arms (12) are provided and/or the support arms are at least in part irregularly spaced.
A wind power installation having a generator, preferably a ring generator, comprising a rotor and a stator which has a mounting means for the stator windings, wherein the stator is held by a support structure, wherein the support structure is so designed that it produces substantially no or only slight sound-emitting natural modes (natural forms) in the normal operating range.
