  • Rotating electrical machine and method of manufacturing a rotating electrical machine
    Publication number: 20030127938
    Abstract: A rotating electrical machine has an inner rotor and an outer stator. Each of the two is wound from a strip. Each strip is subdivided into segments, which are matched to the inner and outer radius of curvature of the rotor or the stator. Each segment is provided with a defined number of slots which are arranged exactly one behind the other when winding the rotor or the stator so that, by this means, cavities are created for accommodating electrical windings.

  • Method for producing a tape
    Publication number: 20020194723
    Abstract: A method for producing finished tapes for winding an annular magnetic core is described. The method includes providing an endless flat strip formed from a metal that conducts a magnetic flux. At least two tapes of equal size are cut out of the endless flat strip. Each of the two tapes is subdivided into sections of equal size having concave bulges and convex bulges. The two tapes have equilateral open triangles cut out of them that have opening angles and heights at predetermined points.
