Abstract: An electromechanical limited rotation rotary actuator comprises a stator having an aperture extending axially therein and at least two teeth having arcuate end portions forming an aperture. A rotor includes a diametral magnetized magnet bidirectionally operable with the stator and extending into the aperture. A non-uniform gap is formed between the magnet and the end portions of the teeth, and wherein the shape of the gap provides a restoration torque resulting in a spring-like return-to-center action of the rotor. An electrical coil extends around at least a portion of one tooth and is excitable for magnetizing the tooth and providing bidirectional torque to the rotor.

Abstract: A generator for a wind turbine is provided. The generator includes a housing with a multi-piece stator arrangement mounted to the housing, the stator arrangement surrounding radially inward and radially outwardly directed faces of a rotor assembly, also surrounded by the housing. The rotor assembly is configured for direct attachment to a wind turbine main shaft so that rotation of the main shaft results in like rotation of the rotor assembly. The housing is mechanically coupled to the rotor by anti-friction elements such that the rotor is free to rotate about its central axis relative to the housing, and such that radial displacement of the rotor due to main shaft deflections results in a like radial displacement of the housing.

Abstract: Wind turbine comprising a generator section with a generator rotor and a generator stator. A first air gap is defined between a first surface of the generator rotor and the stator, and magnets and electro conductive windings are provided at opposite sides of the first air gap to create a magnetic field over the first air gap during operation. The wind turbine comprises distance measurement means arranged to measure the radial length of a second air gap defined between a second surface of the generator rotor and a stationary part of the generator section. The second air gap is located at a radial distance from the first air gap at a position where there is no interference of a magnetic field generated by the magnets over the first air gap, and the length of the second air gap corresponds directly to the length of the first air gap. This enables accurate measurement and monitoring of the air gap length. A method for monitoring the gap length between a rotor and a stator of a wind turbine generator is also disclosed.
