RELUCTANCE ROTOR WITH MECHANICAL STABILIZING

摘要

The invention relates to a reluctance rotor (10) for an electric machine (E), comprising rotor lamination layers (16) made of a ferromagnetic material, wherein each rotor lamination layer (16) has a flux barrier (22) formed by a recess in the rotor lamination layer (16). The problem addressed by the invention is to toughen the reluctance rotor (10) for a high torque and a high rotational speed. For this purpose, the reluctance rotor (10) has an intermediate part (32) with recesses (36) arranged between a first and a second rotor lamination layer (16), and separators (38) delimiting the recesses (36) from one another. The recesses (36) of the intermediate part (32) and the separators (38) are arranged axially between the flux barriers (22), wherein the recesses (36) of the intermediate part (32) and the flux barriers (22) together delimit a space. This space is cast with a non-ferromagnetic casting compound.
