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.

Abstract: A generator rotor assembly (42) comprises a cylindrical ring structure (46) defining a central hollow portion and arranged to rotate around a rotational axis. The cylindrical ring structure (46) comprises a plurality of permanent magnet packages (48) arranged coaxially around the rotational axis, the permanent magnet packages (48) comprising a plurality of coaxially stacked ring-shaped segmented layers (80), a plurality of tie rod holes (86) and a plurality of tie rods (54). The coaxially stacked ring-shaped segmented layers (80) comprise a plurality of contiguous segment sheets (82) arranged around the rotational axis to form the ring-shaped layer, the stacked layers (80) being staggered such that segment breaks between two contiguous segment sheets (82) in one of the layers are angularly offset with respect to segment breaks between two contiguous segment sheets (82) in an adjacent layer. The tie rod holes (86) extend axially through the layers of the permanent magnet packages (48), wherein the plurality of tie rod holes (86) of adjacent permanent magnet packages (48) are complementary in size and position, such that a plurality of tie rod bores is defined. The tie rods (54) extend through respective ones of the plurality of tie rod bores.

Abstract: A wind power generator set, an electromagnetic device and a heat exchange or drying device for an iron core. The heat exchange or drying device for an iron core includes a sprayer capable of feeding an airflow, wherein the sprayer is provided with a spraying hole, and the airflow can be sprayed to an end of the iron core through the spraying hole. The sprayer sprays a cold airflow or a hot airflow at the end of the iron core, creating a cooling and drying environment at the end of the iron core. This facilitates the heat dissipation of the iron core and also the maintenance of the insulation performance of an end of a winding, including the insulation of the winding itself and the insulation between the winding and the iron core, and also the protection of a magnetic pole and a protective covering layer thereof.
