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.
