摘要： Various teachings herein may be used to make a bearing bush for a rotating shaft, wherein a wall of the bearing bush has a wall thickness which amounts to less than 10% of the diameter of the bearing bush. In the axial direction, the bearing bush is made from a plurality of layers connected with a material bond. Each layer has a layer thickness between 10 μm and 200 μm and the wall has closed cavities which are filled with a powder.

摘要： In a method for producing a material layer by an additive process, a first suspension with binding agent and solid particles is applied through a first template onto a base area to obtain a first green body, thereby reproducing by the first template a first material region of a first material to form a magnetic flux-conductive region with a first magnetic permeability μr>50. A second suspension with binding agent and solid particles is applied through a second template onto a base area to obtain a second green body, thereby reproducing by the second template a second material region of a second material to form a flux-blocking region with a second magnetic permeability μr

摘要： A reluctance rotor of a dynamoelectric rotary machine has an even number of poles constructed of a material having structural magnetic anisotropy. The magnetic anisotropy of the material is characterized by a first magnetic resistance, a magnetic permeability of μr>20 and a saturation polarization of >1T in a first spatial direction, and by a second magnetic resistance which is greater than the first magnetic resistance with a magnetic permeability of μr

摘要： A magnetic radial bearing with low eddy current losses is made compact and easily actuable. For this purpose, a radial bearing with four coils (S1, S2, S3, S4) is proposed, said coils lying opposite one another in pairs on two axes (X, Y). The coils are controlled by a three-phase current (U, V and W). The amplitudes of the currents of the phases (U, V and W) are each evaluated using a sine function which is phase-shifted with respect to one another through 120 DEG. The control is performed by a control device at a variable operating point, which fixes the value for the evaluation of the amplitudes for the individual phases corresponding to the respective sine function.

摘要： A permanently excited synchronous machine includes a stator; a winding system arranged in grooves of a laminated core of the stator and forming winding overhangs on end faces of the laminated core, and a rotor connected in fixed rotative engagement to the shaft and having ferrite magnets which extend axially beyond the end faces of the laminated core. The rotor electromagnetically interacts with the stator across an air gap there between during operation of the permanently excited synchronous machine to cause a rotation about an axis of rotation. A flux concentration element is provided radially across each of the ferrite magnets of a magnetic pole and bundles magnetic field lines of the ferrite magnet onto an axial length of the laminated core of the stator. The flux concentration elements and held by a fixing element on the ferrite magnets of a magnetic pole.

摘要： In a method for producing a material layer for a rotor of a dynamoelectric rotary machine, a first suspension with binding agent and solid particles is applied through a first screen onto a base to form a first green body, thereby reproducing a first region of a first material with a first degree of strength. A second suspension with binding agent and solid particles is applied through a second screen onto a base to form an annular second green body concentrically to a layer center, thereby reproducing a second region of a second material with a second degree of strength being higher than the first degree of strength. The first and second green bodies are joined such as to form a material recess substantially at a layer center. A permanent material bond of the first and second green bodies and the solid particles is created by heating and/or by compression.

摘要： A rotating electric machine includes a stator having a segment pair of first and second active part segments, and a rotor mounted for rotation about an axis of rotation relative to the stator and including a ring-shaped reaction element extending along a reaction element circle about the axis of rotation, with a circular arc of the reaction element circle running between the two active part segments. The rotor includes magnetizable regions arranged in series along the reaction element circle, with a non-magnetic region being arranged between two adjacent magnetizable regions. The first active part segment of the segment pair of the stator includes a number of electromagnets arranged in series along a course of the circular arc, and the second active part segment of the segment pair of the stator includes a number of permanent magnets arranged in series along the course of the circular arc.

摘要： A reluctance armature includes a shaft received in a shaft hole in a torsion-proof manner. At least one carrier body is disposed around the shaft and has radial sides as viewed in a circumferential direction. Part segments are arranged on the radial sides of the carrier body and made of anisotropic soft-magnetic material to thereby establish an armature segment which, as viewed in an axial direction, is disposed between two edge elements and forms a central section.
