Abstract

The invention relates to a rotor (10) for a reluctance machine (E), wherein the rotor (10) has a laminate stack (14) with layers (16), each of the layers having a plurality of flux-conducting portions (24) which are formed in each case by a magnetically conductive rotor lamination (18) and extend between two adjacent d-axes and transversely to a respective q-axis (30), wherein the flux-conducting portions (24) are separated from each other by in each case a flux barrier (22) which is filled with a casting compound. The aim of the invention is to additionally provide a permanent magnetic excitation in the rotor (10) without degrading the reluctance of the rotor. To this end, the invention provides that the casting compound comprises permanently magnetic particles (36) in one or more or each of the flux barriers (22).
