Abstract: PROBLEM TO BE SOLVED: To mechanically and permanently connect an external stator ring and an internal stator ring, without the use of a bonding agent by mechanically bonding these rings by winding them with a strip. SOLUTION: Any of the external stator ring 4 and internal stator ring 5 is manufactured from a strip of the particular shape. A strip used to wind an external stator ring 4 is provided with wedge-type notches 4K at a constant interval. Each notch 4K in the layer is covered completely with a closed part when the strip is wound, which does not, result in formation of gap. Meanwhile, the internal stator ring 5 is manufactured with a strip providing tooth-shape using a similar method. The internal stator ring 5 is cooled, an external stator ring 4 is heated, and the internal stator ring 5 is pushed into the external stator ring 4. As a result, two stator rings 4 and 5 are connected permanently rigidly, when these are returned to the room temperature.

Abstract: From an endless, flat metal strip are cut at least two tapes (1,3), or an integral multiple of two. The metal is of good conductivity of magnetic flux. The strip width is adapted to that of two tapes, or less, and the strip thickness is adapted to the required tape thickness. From the strip are cut-out at least two tapes of identical size, and from each tapes are stamped out isosceles triangles (2D,3D) at preset points with defined opening angle and height. In the inner apex of each triangle is made a hole (2L,3L) with preset cross-section.

Abstract: The electric machine has an inner lying rotor and an outer lying stator which is assembled together from an external stator ring and an inner stator ring without use of adhesive. The outer stator ring (4) and the inner stator ring (5) are wound respectively from at least one ring strip (4B,5B) and are connected mechanically permanently with each other. The outer stator ring and the inner stator ring are meshed to each other.

Abstract: The invention relates to a rotating electrical machine (1) with an internal rotor (2) and an external stator (3). Both are rolled from a strip (5, 6). Each strip (5, 6) is divided into segments (51, 61) which match the internal and external radius of curvature of the rotor (2) or the stator (3). Each segment (51, 61) has a defined number of slots (52, 62), which, on rolling the rotor (2) or the stator (3) are arranged exactly behind one another, such as to form cavities (2H, 3H) for the fixing of electrical windings.
