摘要： The invention relates to a steel strip for producing a non-oriented electrical steel. To achieve greatly improved frequency-independent magnetic properties, in particular greatly reduced hysteresis losses, in comparison with known electrical steels, the following alloy composition in wt % is proposed: C: ≤0.03, Al: 1 to 12, Si: 0.3 to 3.5, Mn: >0.25 to 10, Cu: >0.05 to 3.0, Ni: >0.01 to 5.0, total of N, S and P: at most 0.07, remainder iron and smelting-related impurities, with the optional addition of one or more elements from the group Cr, Mo, Zn and Sn, wherein the steel strip has an insulation layer substantially consisting of Al2O3 and/or SiO2 with a thickness in the range from 10 μm to 100 μm. The invention also relates to a method for producing such a steel strip.

摘要： An electric drive includes a power component and an electric machine which is supplied with electrical energy via the power component. The power component is embodied as an inverter. When a starting condition is met, a drive controller for controlling the electric drive retrieves a configuration-specific parameter set from a data pool via a computer-to-computer interface, parameterizes itself in accordance with the retrieved parameter set and then determines control commands for the power component as a function of setpoint actuation states predefined for the drive controller, taking into account their parameterization, and actuates the power component accordingly. The setpoint actuation states are setpoint currents.

摘要： A discontinuously operated centrifuge, in particular sugar or starch centrifuge, includes a rotating, cylindrical centrifuge basket having a casing provided with openings and having an upper open end. An inner screen element formed as a composite unit of a screen mat and a support mat is insertable as a prefabricated, single-piece screen element into the centrifuge basket via the upper open end thereof. The screen element has ends abutting in a circumferential direction within the centrifuge basket, with axially extending end strips attached to the abutting ends of the screen element. A closure element in the form of an axially extending clamping strip cooperates with the end strips so as to lock and radially brace the screen element against the centrifuge basket casing. Attached on the centrifuge basket is an upper limiting flange, with an annular cover being screwed onto an upper limiting flange for securing the screen element.

摘要： In a method for 3D radius correction in CNC milling, a mill path of an original milling tool producing a surface contour on a workpiece is calculated for an original milling tool based on dimensions of the mill cutter tip, with the positions of the mill cutter tip specified by an NC program. A surface normal of an end face milling surface and a surface normal of a circumferential milling surface are then specified, for each position of the mill cutter tip taking into account dimensional differences between an actually available milling tool and the original milling tool. By specifying along the mill path a spatial orientation of the milling tool axis, a correction vector is specified from the milling tool orientation, dimensional differences and the surface normals, and the workpiece is machined by traversing the mill path with the actual milling tool under consideration of the correction vector.

摘要： A semiconductor assembly includes a semiconductor element having contacts on a first surface electrically connected with contacts of a carrier element by electrically conductive material. A second surface opposite the first surface has a convex curvature with a first radius or a concave curvature with a second radius. The second surface of the convex curvature or the second surface of the concave curvature is connected in a positive-fit manner to a cooling body surface of a concave cooling body curvature of the cooling body, and, during operation at a selected barrier layer temperature, the first radius of the convex curvature deviates by at most 10% from a third radius of the concave cooling body curvature, or the second radius of the concave curvature deviates by at most 10% from a fourth radius of the convex cooling body curvature.

摘要： A phase module for a power converter includes first and second busbars and at least two semiconductor modules. The first busbar is connected to AC voltage connections of the semiconductor modules. The second busbar is connected to DC voltage connections of the semiconductor modules. At least one section of the first and second busbars is arranged at a distance to one another, the value of which is less than half the value of the distance between the AC voltage connection and the DC voltage connection of one of the semiconductor modules. At least one of the busbars has a separator arranged at a right angle on the remaining part of the busbar and connecting the busbar to at least one of the DC voltage connections or one of the AC voltage connections of one of the semiconductor modules. The separator is arranged along a surface of the one semiconductor module.

摘要： A stent has a center length section, two end sections, and an elastically deformable woven wire mesh, which enables the stent to expand from a small diameter to a larger diameter, with the diameter of the end sections being larger than in the center length section in the expanded state. The wire extends in a zig-zag manner from an outer end of one end section toward the outer end of the other end section, and back in a zig-zag manner to the one end section. The peripheral direction of the woven wire changes at the transition from an end section to the center length section, such that the wire intersects on the return path to the one end section in the center length section and overall forms an 8-shaped loop having two closed eyes, wherein a plurality of interconnected loops are arranged offset to each other over the circumference.
