Abstract: A rotating electric machine has a semiconductor magnetic sensor and a cylindrical housing with a cylinder part, which is made of a soft magnetic material, positioned closer to the semiconductor magnetic sensor relative to a back yoke of a stator core. The semiconductor magnetic sensor is positioned away from the cylindrical housing so that a shortest distance between a center of the semiconductor magnetic sensor and the cylindrical housing is equal to or greater than 50 times of a sum of a first space distance and a second space distance. With such an arrangement, a leak magnetic field generated by magnetic poles that leaks in an axial direction is prevented from disturbing the semiconductor magnetic sensor. Thus, a rotation position detection accuracy of the semiconductor magnetic sensor is improved.

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.

Abstract: An electromagnetic drive mechanism (10) comprises a rotor (50) configured to rotate within a stator (30). The rotor (50) and stator (30) have multiple poles (56, 36), wherein each pole comprises a radial inner portion (564, 362) and a radial outer portion (562, 364). The radial inner portions (564, 362) and radial outer portions (562, 364) of the rotor (50) and stator (30) have different heights, forming a step (566, 366) between the radial inner and outer portions of the rotor (50) and stator (30). This configuration allows for overlapping radial surfaces in addition to overlapping axial surfaces during operation of the drive mechanism (10), thereby increasing the total overlap area and thus the reluctance torque, and potentially improving response speed while allowing for a more compact device (10).
