Abstract
The present disclosure relates to an armature for a wind turbine generator. The generator may be a permanent magnet generator. The present disclosure further relates to methods for operating such armature, generator and wind turbine. A method may include partially short-circuiting the armature windings by closing a first switch and inducing currents in the armature windings by the wind acting on the wind turbine blades.

1-15. (canceled)
A method for operating a wind turbine having a rotor with one or more wind turbine blades and a generator having an armature, wherein the armature has three or more windings and is configured to provide three or more electrical phases, wherein a first winding is configured to provide a first electrical phase and a second winding is configured to provide a second electrical phase, the second electrical phase and the first electrical phase being out of phase, the method comprising:
- partially short-circuiting the armature windings by closing a first switch between an output wire of the first winding and an output wire of the second winding;
- and
- inducing currents in the armature windings by wind acting on the wind turbine blades.
An armature for a wind turbine generator, the armature comprising:
- three or more windings configured to provide three or more electrical phases, wherein a. first winding is configured to provide a first electrical phase and a second winding is configured to provide a second electrical phase, the first electrical phase and the second electrical phase being out of phase;
- each of the winding comprising an output wire;
- and
- a first switch configured to selectively connect the output wire of the first winding and the output wire of the second winding.
