    摘要: An electrical turbo-machine includes a stator (101), a rotor (102), and a turbine section (110) driven with a working flow containing vaporizable material, for example water, in vaporized form. The rotor includes cooling channels (106-109) for conducting, through the rotor, a cooling flow containing the vaporizable material in liquid form. The rotor is arranged to conduct the cooling flow through an area where an impeller or impellers (111-114) of the turbine section are directly connected to the rotor and conduct the cooling flow to a same room to which the working flow comes out from the turbine section. The above-presented cooling system facilitates constructing the electrical turbo-machine as a hermetic structure in a power plant where bearings of the electrical turbo-machine are lubricated by the vaporizable material, a supply pump is directly connected to the rotor, and the vaporizable material in gaseous form fills the gas spaces of the stator.

    摘要: A semiconductor module includes a baseplate, a cover element attached to the baseplate so that detaching the cover element from the baseplate requires material deformations, and a semiconductor element in a room defined by the baseplate and the cover element. The semiconductor element is in a heat conductive relation with the baseplate and an outer surface of the baseplate is provided with laser machined grooves suitable for conducting heat transfer fluid. The laser machining makes it possible to make the grooves after the semiconductor module has been assembled. Therefore, regular commercially available semiconductor modules can be modified, with the laser machining, to semiconductor modules as disclosed.

    摘要: A radial turbine impeller includes a turbine wheel module including a first surface and a second surface being mutually opposite in the axial direction of the radial turbine impeller. The radial turbine impeller includes blade modules attached to the turbine wheel module. Each blade module is a single piece of material and includes a body portion and blades connected to the body portion and protruding in the axial direction from the body portion. At least the first surface of the turbine wheel module is provided with one or more annular grooves opening in the axial direction and containing the body portions of the blade modules so that, in each of the grooves, the blade modules are successively in the circumferential direction. The radial turbine impeller further includes a securing system for keeping the body portions of the blade modules in the one or more grooves.

    摘要: A rotor assembly for an axial magnetic bearing includes a shaft portion and a disc attached to the shaft portion. The disc includes a conical surface on a portion reaching radially from the aperture of the disc a distance away from the aperture. A fastening mechanism includes an aperture for the shaft portion so that the fastening mechanism includes a conical surface matching the conical surface of the disc. The fastening mechanism and the shaft portion are shaped to enable the fastening mechanism to be tightened axially against the conical surface of the disc so as to arrange the conical surface of the fastening mechanism to press the conical surface of the disc towards the center line of the shaft portion. Thus, the fastening mechanism acts against the centrifugal force and keeps the disc centric placed.
