Abstract

A rotor for a reluctance motor having a laminate stack of layers is disclosed. Each layer has at least one magnetically-conductive rotor lamination, and in each layer a plurality of flux-conducting sections are formed by the at least one rotor lamination, which flux-conducting sections are separated from one another by a nonmagnetic region. The invention addresses the problem of enabling a high torque and a high speed. For this purpose, an insert disk is arranged between at least two of the layers, connected in each case to at least two flux-conducting sections of one of the layers or both of the layers between which said insert disk is arranged and, as a result, connects said flux-conducting sections to one another beyond the nonmagnetic region located there between.
