Abstract: The invention relates to a reluctance rotor lamination that permits easy assembly of a rotor, in particular by means of press fitting, wherein there must be sufficient stability. For this purpose, a reluctance rotor lamination (18) is provided, wherein an opening (6, 42) for stress reduction is arranged on each d axis half (32) in each flux-conducting section (24), such that a partial flux-conducting section (36, 37) is formed on each of the two sides of each d axis half (32) in each flux-conducting section (24). The sum of the smallest cross-section of each of the two partial flux-conducting sections (36, 37) is substantially greater than or equal to a smallest cross-sectional area of the flux-conducting section (36, 37) perpendicular to each partial d axis half (32) radially above the opening, such that the opening (6, 42) does not cause magnetic impairment.

Abstract: The invention relates to an electric machine (1) having a stator (2), with magnetic-field-conductive material, in which substantially axial grooves (4) are positioned, wherein a winding system (3), which is surrounded and/or penetrated by impregnating resin, is provided in the grooves, wherein the impregnating resin has energy-absorbing particles (7).

Abstract: A reluctance rotor for an electric machine includes rotor lamination layers made of a ferromagnetic material, wherein each rotor lamination layer has a flux barrier formed by a recess in the rotor lamination layer. In order to toughen the reluctance rotor for a high torque and a high rotational speed, the reluctance rotor has an intermediate part with recesses arranged between a first and a second rotor lamination layer, and separators delimiting the recesses from one another. The recesses of the intermediate part and the separators are arranged axially between the flux barriers, wherein the recesses of the intermediate part and the flux barriers together delimit a space. The space is cast with a non-ferromagnetic casting compound.
