Abstract: The disclosure relates to a method for designing a stator segment for a stator of an m-phase synchronous reluctance machine with concentrated windings, the stator being divided into a stator segment or a plurality of stator segments and comprising a ferromagnetic base body with peripherally distributed tooth structures and a winding system mounted in the base body, which comprises, per stator segment, z tooth structures and a number of winding phases (U, V, W) corresponding to the number of phases m, each of said winding phases comprising a series connection and/or a parallel connection of a plurality of the concentrated windings, a rotor of the synchronous reluctance machine comprising a pole number p in a peripheral section corresponding to the stator segment.

Abstract: The invention relates to an arrangement in the form of an electric ring machine in the implementation of a reluctance machine which is operated as a synchronous reluctance machine, in which recesses are formed at the outer side of the rotor sheets in the radial extension opposite to the inner barriers. These result in webs which hold and enclose the barriers and can thus be manufactured in a defined manner at both sides, even if the finished assembled rotor design is later finally mechanically reworked at the outer side. In addition to the rotor, the invention also relates to a corresponding electric ring machine and a method for producing such a rotor.
