Abstract: A wind turbine having an electrical power generation assembly and a control device for controlling the power generation assembly is provided, the electrical power generation assembly including a generator, at least one converter connected to the generator, and an overheating detection device, wherein the overheating detection device includes—at least two temperature sensing elements at different positions of the power generation assembly, wherein the temperature sensing elements are connected in series along a signal line to provide a common sensor signal and are each adapted to indicate the exceeding of a respective critical temperature at their position in the common sensor signal, and—a detection unit for evaluating the common sensor signal, which is connected to the signal line.

Abstract: A permanent magnet electrical machine is provided including a rotor body and a plurality of permanent magnet modules arranged around a rotational axis of the permanent magnet electrical machine, each permanent magnet module including at least a permanent magnet and a baseplate, the baseplate including a base side for attaching the permanent magnet module to the rotor body of the permanent magnet machine and an opposite top side for attaching the permanent magnet to the baseplate. The rotor body includes at least a cavity housing a non-magnetic and/or non-conductive medium for creating a magnetic flux barrier between the rotor body and the permanent magnet module. The baseplate may include a protrusion. The protrusion may be shaped as a dovetail. One or elastomeric inserts may be provided between the baseplate and the rotor body.

Abstract: An electromechanical transducer includes a stator assembly and a rotor assembly including a rotor shaft having a longitudinal axis, a mounting structure connected to the rotor shaft, and at least one magnetic component part including at least one permanent magnet, wherein a skew angle between the permanent magnet and the stator assembly has a value of 60% to 92% of a cogging torque period, or for an integral machine, wherein the skew angle between the permanent magnet and the stator assembly has a value of 35° to 55° electrical degrees.
