Abstract:
A wind turbine rotary electric machine having a tubular body, in turn having a cylindrical wall; and a plurality of clips formed integrally with the cylindrical wall and configured so that each pair of facing clips defines a seat for housing an active sector.
Abstract:
A rotating machine has a stator and a permanent magnet rotor that is more easily made, lower cost, and lighter by virtue of a plurality of permanent magnet assemblies mounted on a rotor body. Each magnet assembly includes two facing core plate stacks supporting a permanent magnet between them. Each core plate stack is made from a plurality of core plates of substantially identical size and shape and with on or more holes in substantially the same location to form respective bores in the stack. A tie rod is formed in each bore and retains the plates in a stack via bevels in the holes of the end plates. Preferably, the tie rods also apply compressive force as a result of placing the stacked plates in an injection mold, injecting plastic into the mold to fill each bore with plastic, and allowing the plastic to cure. As the plastic cures, it shrinks so that the tie rods pull the end plates together. To enhance the pressure, the stacked plates can be compressed before and during the injection process.
Abstract:
A damper is described for cableway traction cables comprising a carrying cable (2) stretched between a downstream station and an upstream station with a traction cable (3) returned by pulleys in the stations and at least one support (9) of the cables (2, 3) provided along the path of the cableway and bearing a support and a roller battery and a plurality of cabins (4) running along the carrying cables (2) and can be coupled with the traction cable (3) by means of clamps (6).In accordance with this invention to the structure of the roller battery and preferably at the entrance of the roller battery in the direction of movement (16) of the cabins there is joined a lever (12) bearing at its free end a roller (13) engaged on the traction cable (3) and the lever is loaded by elastic means or weights towards the traction cable in such a manner as to soften the passage of this roller over the back of the clamp and to accompany the traction cable in the lowering onto the roller battery.
Abstract:
A segmented electric generator/motor, such as for a wind powered generator, in which the rotor and/or stator is subdivided in the circumferential direction into segments disposed adjacent to one another. Additionally, the stator segments are accessible via and the rotor segments can be installed and removed in the axial direction in rotor segment mounts provided in the rotor ring. Each rotor segment preferably includes a base shaped to prevent radial and circumferential or tangential motion of the rotor segment while permitting axial motion in the rotor segment's respective mount. The rotor ring segment mounts are preferably sized to allow removal of stator segments through the openings.
Abstract:
A double-acting trolley for a one-cable installation support for chair lifts and cabin lifts, includes a bearing member mounted in a swinging manner to a one-cable installation support, and supporting two equalizers respectively below and above the one cable and with each equalizer having at least two rollers engaged with the cable. Also, above and below the cable the respective two equalizers are articulated centrally and respectively to supports each of which is articulated in an elastically damped manner at one end to the bearing member.
Abstract:
A wind turbine having an electric machine in turn having a stator, and a rotor which rotates about an axis of rotation with respect to the stator; the rotor having a number of magnetized modules, and a number of supports for supporting the magnetized modules and arranged about the axis of rotation; and wherein at least two of the supports are parallel connected electrically.
Abstract:
A wind turbine having an electric machine, in turn having a stator, and a rotor which rotates about an axis of rotation with respect to the stator; the rotor having a plurality of magnetized modules, and a rotor cylinder which extends circumferentially, rotates about an axis of rotation, and is configured to support the plurality of magnetized modules; and wherein the rotor cylinder is made of nonmagnetic material.
Abstract:
A rotating machine with a permanent magnet rotor that is easier, lower cost, and lighter includes a plurality of permanent magnet assemblies (20) mounted on a rotor body (1). The magnet assemblies (20) are mounted via magnet holders that each include a pair of claws (2, 3) connected by a bridge (5) and forming a seat for a respective magnet assembly (20). The claws have terminal expansions (11) that extend beyond the bridge (5) and form a second seat in which a tightening section (9) is received. The claws (2, 3) can elastically pivot about the bridge (5) when the terminal expansions (11) are squeezed together or forced apart, allowing insertion of and securing the magnet assembly, respectively.
Abstract:
The invention relates to a cable derailing prevention device for carrier/traction cables of cable car systems in an installation including: a carrier/traction cable; a multitude of rollers which flank a coupling rail and are located at the exit from the station; a multitude of clamps from which the driving means are suspended; at least one roller that has a couple and clamp and supports the cable, and a support roller or hold-down roller battery according to the cable guide, the coupling rail forming a coupling area between the cable and the clamps. According to the invention, an aligning device is mounted in front of the coupling area of the clamps on the cable before the coupling rail and limits the deviation of the cable due to a derailing on the roller battery so that the cable is always located inside the opening of the clamp.
