A method for the non-destructive detecting of ageing symptoms of a component having regularly recurring structures, includes the following steps: a) scanning the component in the region of the recurring structures in a plurality of scanning planes which extend parallel to one another to create at least one scanning image set having a plurality of two-dimensional scanning images, wherein the scanning images show a plurality of inhomogeneities; b) automatically identifying those inhomogeneities that form recurring patterns, and those inhomogeneities that do not follow a recurring pattern, using a suitable algorithm; and c) detecting ageing symptoms exclusively on the basis of those inhomogeneities which are identified in step b) and do not follow a recurring pattern.

The invention relates to a control system for reducing rotor vibrations, in particular the variability thereof, in shafting, in particular turbine shafting, in which the temperature of the bearing () of the shaft is measured and the oil () supplied to the bearing is adjusted to a temperature as is assigned as the output variable in an allocation for minimised rotor vibrations with the measured temperature of the bearing as the input variable. The allocation can, for example, be provided by an initial measurement of the rotor vibrations or by a self-learning system. According to the invention, the variability of the rotor vibrations is restricted.

An apparatus for angle-based localization of a position on a surface of an object includes an orientation sensor configured to be arranged in a known relationship relative to a position, to be identified, on a surface of an object at at least one measurement time and to capture angle information items in respect of the current orientation thereof at the measurement time, and a programmable device, with a processor and a memory, wherein the memory contains instructions and at least one assignment prescription for the object with the surface, where angle information items are assigned associated positions on the surface of the object, and wherein the instructions cause the programmable device to receive the angle information items captured at the measurement time by the orientation sensor and to establish the position to be identified by an assignment to the captured angle information items on the basis of the assignment prescription.

An electric machine having a stator and a rotor arranged on an axis of rotation and a first fan, which extends in the radial direction on one section of the axis of rotation and delivers a coolant flow into the electric machine during operation. The electric machine further includes a fan directing element, which interacts with the first fan and deflects at least a proportion of the coolant flow. Variable and demand-based cooling of the electric machine can be achieved by the fan directing element, which can in particular be adjustable.

A cooling device for an electric motor includes at least one closed capillary tube, within which a cooling fluid is located and which is introduced into an opening of a lamination stack of the electric motor such that the capillary tube is connected to the lamination stack to conduct heat and partially projects out of the lamination stack, such that the capillary tube has a cold end disposed outside and a hot end disposed inside the lamination stack. The cooling fluid and the degree of filling of the capillary tube with the cooling fluid is chosen such that an input of heat from the lamination stack into the capillary tube leads to evaporation of the cooling fluid, and the cold end of the capillary tube is cooled such that vapor produced during the evaporation condenses and heat input into the capillary tube is dissipated out of the capillary tube.
