Problems solved by technology

[0006] Locking devices known from the prior art can provide locking of the rotor, however such a rigid connection of the generator rotor and the generator stator causes the vibrations of these two components to superimpose, whereby the results of the modal analysis are distorted

Embodiment Construction

[0046] figure 1 A wind energy installation 100 is shown with a tower 102 and a nacelle 104 . A rotor 106 with three rotor blades 108 and a spinner 110 is arranged on the pod. The rotor blade 108 is arranged with its rotor blade root on the rotor hub. The rotor 106 is set in rotational motion by the wind during operation and thus drives a (not shown) generator in the nacelle 104 .

[0047] figure 2 A generator 120 is shown, in particular for a wind energy installation 100, having a rotatably mounted generator rotor 121, a generator stator 122 corresponding to the generator rotor 121, which has a The load-bearing structure 123 in the wind energy installation 100 . The stator carrying structure 123 also has a plurality of segments 123a, b, c and at least a first side 123' and a second side 123".

[0048] Each section of the stator carrying structure 123a,b,c has at least one first side 123'a,b,c and a second side 123"a,b,c. Furthermore, at least three Locking devices 130 a...

Abstract

The invention relates to a generator, in particular a generator (120) for a wind turbine, comprising a rotatably mounted generator rotor; a generator stator which corresponds to the generator rotor (121) and which has a support structure (123) for securing in the wind turbine (100); and at least one locking device which can be coupled between the generator rotor (121) and the generator stator (122) such that a force flow between the generator rotor (121) and the generator stator (122) is produced and which is designed to lock the generator rotor (121) relative to the generator stator (122) ina specified position in the coupled state. According to the invention, the locking device (130) has a damping element (131) which is designed to have a variable shape so as to deform as a result of the force flow between the generator rotor (121) and the generator stator (122).
