    摘要: According to the invention, in order to construct a rotor (100) of an electrical machine (101) in a simple and cost-effective manner and, in the process, achieve low skin effect losses and a high tilting moment using low tooth tip distribution, the rotor (100) is to be constructed with a substantially cylindrical laminated core (102) comprising axially (A) layered metal sheets, wherein substantially axially (A) extending grooves (103) are formed in the laminated core (102) along a circumferential surface (104) of the laminated core (102), of which grooves some are configured to be open to the circumferential surface (104) via a respective scattering slit (108) extending radially (R) outwards from the groove (103) to said circumferential surface (104), and wherein the electrically and magnetically non-conductive closure elements (110) are accommodated in the scattering slits (108), extending in the axial direction (A) thereof and at least partially interlockingly locking the grooves (103) to the circumferential surface (104). The invention also relates to an electrical machine (101) comprising a rotor (100) of this type and a method for producing a rotor (100) of this type.

    摘要: The invention relates to a method for repairing an electric generator, preferably in a wind turbine generator (WTG), the electric generator (10) having a stator and a rotor (30) rotatably mounted relative to the stator. The method of repairing the electric generator provides a rotor connecting ring (40) with a first conductor assembly and a second conductor assembly in two different planes, each assembly with a plurality of conductive arc segments. Each of the first and the second plurality of conductive arc segments form a ring-like shape in their respective plane, both ring-like shapes being concentrical to the central shaft (132) when the rotor connecting ring is mounted. First electrical connections (50) from the central shaft connect to the rotor connecting ring for the multiple phases (K,L,M). Second electrical connections (60) further connect from the rotor connecting ring to the respective windings of the multiple phases (K,L,M) on the exterior part of the rotor facing the stator. The rotor connecting ring enhances rotational and thermal stability of the electric generator.

    摘要: The present invention provides a linear actuator in which a distance between a movable element and a stationary element, where a damper member is inserted, is accurately controlled. For example; a linear actuator 1 includes; a movable element 2, a stationary element 3, and a damper member 5 placed between the movable element 2 and the stationary element 3. The stationary element 3 is provided with a coil bobbin 31 that supports the movable element 2 via a spring 4 in such a way as to be movable, and a base 32 that overlaps with the coil bobbin 31 from a side opposite to the movable element 2. The coil bobbin 31 is provided with projection parts 40 protruding toward the base 32. The damper member 5 is inserted between a bottom surface 11a of a core member 11 of the movable element and a top surface 32a of the base 32. By way of crushing tip parts of the projection parts 40, a distance between the bottom surface 11a of the core member 11 and the top surface 32a of the base 32 is made so as to have a specified dimension 'S' that is a length of the damper member 5.
