    Abstract: A direct-drive wind turbine comprises a wind turbine rotor and a generator mounted on a frame. The wind turbine rotor comprises a hub carrying blades and the generator comprises a generator stator comprising a track structure and a stator surface connected to the track structure, wherein the stator surface has coil windings, and carriages connected one after the other and adapted to run on the track structure, wherein the carriages carry an electrically magnetically active material facing the stator surface such that when the carriages run along the track structure a magnetic field is generated across an air gap provided between the carriages active materials and the stator coil windings, wherein one or more carriages are directly coupled to the wind turbine rotor by rigid connectors such that rotation of the wind turbine rotor causes displacement of the carriages along the track.

    Abstract: A permanent magnet rotor comprises a rotor body configured for rotating around a central rotational axis and further comprises principal permanent magnets that are substantially rectangular in axial cross-section and are embedded in the rotor body and are arranged inclined with respect to the radial plane extending through the center of the principal magnets and such as to have a circumferential magnetic orientation. The principal magnets have an inner end and an outer end, the outer end being arranged in the proximity of the air gap of the outer circumference of the rotor, and outer bridges of magnetically conductive material being formed between the outer ends of the principal magnets and the outer circumference of the rotor. Auxiliary magnets are arranged near the outer ends of the principal magnets to magnetically saturate the outer bridges.

    Abstract: The invention proceeds from a rotating electric machine, in particular a double-fed induction machine in the power range between 20 MVA and 500 MVA, which comprises a rotor that rotates about a machine axis, is concentrically surrounded by a stator, and has a rotor plate body and a shaft, which rotor plate body bears a rotor winding that is arranged further outwards and is connected by means of connectors to slip rings that are arranged further inwards at the end of the shaft. A flexible and secure connection is achieved in that the connectors have mechanical connectors that run at right angles to the shaft to absorb forces arising owing to centrifugal acceleration, which mechanical connectors are connected on one side to a rotor winding head of the rotor winding and are supported on the other side on an auxiliary rim on the rotor plate body.

    Abstract: The present invention generally relates to a runner unit of a tidal power plant, and more particular to a device for reversing a blade of the runner unit. The device according to the invention is lighter and more efficient with respect to known solutions which involve articulated mechanisms as it is based on an auxiliary servomotor including a reciprocating linear rack which acts on the blade to be reversed.
