A method is provided for carrying out a sound test for detecting and/or analyzing material faults and/or mounting faults of at least one component, in which the component is excited, by striking, to experience vibrations which generate soundwaves, after which the generated soundwaves are detected and conclusions are drawn about material faults and/or mounting faults on the basis of the detected soundwaves, wherein the striking of the component and the detection of the vibrations are carried out using an endoscope device. In addition, embodiments of the present invention relates to an endoscope device which is configured to carry out the method.

A device for deflecting at least a portion of a cooling fluid flowing axially in an intermediate space is arranged between a rotor and a stator of a rotating electrical machine, in particular of a turbogenerator, wherein at least one blade can be arranged on a prespecifiable section of an outer face of the rotor and in the intermediate space, which blade is designed and can be arranged in such a way that a portion of the cooling fluid flowing in the intermediate space can be radially deflected in the direction of the stator by said blade.

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.
