摘要： One or more bolt gauges each with a built-in load cell are positioned on a blade bolt or a bearing bolt between a pitch bearing and a tightening means and tensioned by the securing means at the inside or the outside of a hub of a wind turbine. The bolt gauge then outputs a signal descending both from the tension from the bolt/securing means connection and the tension from the blade when the blade is vibrated due to wind forces and the rotation of the blade when the hub of the wind turbine is rotating.

摘要： A thermal energy storage device is provided. The device has a heat exchanger arrangement for guiding a flow of a heat transfer medium between a first end and a second end of the heat exchanger arrangement, and a heat storage material surrounding the heat exchanger arrangement. The heat exchanger arrangement transports the heat transfer medium from the first end to the second end if the thermal energy storage device is in a first operational mode, in which the heat storage material is supposed to receive thermal energy from the heat transfer medium, and transports the heat transfer medium from the second end to the first end if the thermal energy storage device is in a second operational mode, in which the heat storage material is supposed to release thermal energy to the heat transfer medium.

摘要： An arrangement to ensure an air gap in an electrical machine is provided. The electrical machine has a stator arrangement and a rotor arrangement, the rotor arrangement rotating around a longitudinal axis. An air gap is defined by a distance between parts of the rotor arrangement and parts of the stator arrangement, wherein the parts of the stator arrangement are opposite to the parts of the rotor arrangement along a certain length. The stator arrangement includes a lamination stack which is constructed to support a winding of a stator-coil, and the rotor arrangement includes a plurality of permanent magnets. A cross section of the air gap changes along the certain length such that the air gap is not uniform in view to the certain length. The cross section of the air gap is configured by a change in a shape of the lamination stack along the certain length.
