摘要： A tower for a wind turbine may include an upper tower portion and a lower tower portion. The upper tower portion may include a tubular tower, and the lower tower portion may include a lattice tower. To improve ergonomics and work safety and make it possible to obtain a structural design with optimized forces, the lower tower portion may include a central tube positioned centrally within the lattice tower. Further, the central tube may have a smaller diameter, at least in certain portions, than at least part of the tubular tower of the upper tower portion. The tower may also include a transition piece between the upper tower portion and the lower tower portion. The transition piece may join the tubular tower of the upper tower portion and the central tube of the lower tower portion.

摘要： A transition body may be disposed between upper and lower tower sections of a tower for a wind power station. Some example transition bodies may include a substantially annular upper connection flange for connection to the upper tower section, and at least three substantially annular lower connection flanges, each of which may connect to a corner leg of the lower tower section. The transition body may have several segments disposed about a central tower axis, with the number of segments corresponding to the number of corner legs. Upper peripheral sections of the segments may form an annular circumferential connection envelope that supports the upper connection flange. Lower sections of the segments may form annular circumferential segment envelopes that support the lower connection flanges. The segments may be disposed at acute angles and converge into one another at or near the upper connection flange.

摘要： The invention relates to a tower of a wind power plant, having a lower part in the form of a lattice tower or truss tower with at least two corner bars, and an upper part in the form of a cross-sectionally substantially round tubular tower, wherein each particular corner bar is put together from a plurality of steel tube profiles that are connected together in the longitudinal direction. In order to achieve good transportability and easier assembly of the components of such a tower, the invention proposes a modular tower concept. According to the invention, each particular corner bar is in this case put together from at least three steel tube profiles which are provided with perforated flanges for holding screws, wherein the corner bars are connected together by cross struts and/or tension struts attached to the flanges, and wherein the steel tube profiles of each particular corner bar are spirally welded steel tube profiles.

摘要： An electric motor with a beveled stator and/or rotor has at least one layer of a composite material. The composite material has at least one electrical steel strip layer as carrier and at least one polymer layer. The composite material can be used for reducing acoustic emission in beveled electric motors. A method of reducing acoustic emission in these electric motors is based on the use of the composite material.

摘要： Methods for producing connecting or junction elements, which in some cases may be utilized in steel structures of towers for wind turbines, may involve using a flow forming process to produce which a flange and a casing integrally adjoining the flange from a blank. Further, an end of the casing opposite the flange may be adapted to a contour of a component to which the casing is intended to be connected. In some examples, the casing may be formed with a second flange. Likewise, in some examples, at least a portion of the casing may have a conical design.
