A stator assembly is provided including (a) an inner frame structure having an annular shape with an inner circumferential edge and an outer circumferential edge, wherein the inner frame structure is formed around a center axis corresponding to an axial direction of the electric generator; and (b) an outer frame structure, which surrounds the inner frame structure and which, starting from the outer circumferential edge, includes two inclined annular walls which, along a radial direction, spread apart from each other such that in between a first inclined annular wall and the second inclined annular wall there is formed an accommodation space. Preferably, the inner frame structure and the outer frame structure are made from a single piece.

Stator assembly for an electric generator with accommodation space

An electric generator is provided including a stator assembly, a rotor assembly being rotatably supported at the stator assembly for rotating around a rotational axis, an annular device being fixed to the rotor assembly and including an engagement structure, and a first turning device being mounted to the stator assembly, the first turning device including an actuator and an engagement element being drivable by the actuator. The first turning device is configured for adopting two operational states, an active operational state and a passive operational state. In the active operational state there is an engagement between the engagement element and the engagement structure and in the passive operational state the engagement element and the engagement structure are mechanically decoupled from each other.

Rotational movement control of an electric generator by means of a turning device

A stator assembly includes a stator frame structure having an outer annular frame with an outer edge running around a center axis; a plurality of stator segments mounted at the outer edge along a circumferential direction of the outer edge, each stator segment comprising at least one electric coil; and a wiring arrangement electrically connecting the stator segments with an electric power interface. The wiring arrangement comprises a plurality of wiring assemblies, each wiring assembly electrically connecting one of the plurality of stator segments with the power interface is provided. Each wiring assembly is routed along and next to the outer annular frame and comprises electric cables connected in between the electric interface and the respective stator segment, wherein the electric cables are provided with electric insulation structures each surrounding one of the electric cables. Further described is an electric generator and a wind turbine with such a stator assembly.

An airflow control arrangement for a direct-drive wind-turbine with a generator comprising a rotor and a stator, which airflow control arrangement comprises an outflow fan arranged to draw an exit airflow through an exit duct, which exit duct extends from an interior cavity of the stator to the exterior of the wind turbine. The invention further describes a direct-drive wind turbine comprising such an airflow control arrangement. The invention further describes a method of controlling an airflow in a direct-drive wind-turbine with a generator comprising a rotor and a stator is provided.

Airflow control arrangement

A bearing for a wind turbine, the use of the bearing and a method to control the temperature of the bearing is provided. A bearing for a wind turbine comprises an inner ring and an outer ring. The inner ring and the outer ring are prepared and arranged in a way to rotate with respect to each other. The inner ring comprises at least one channel. The channel is prepared and arranged in a way that air flows along inside the channel so that excess heat of the inner ring is removed by the airflow in the channel.
