Abstract

A rotor includes a shaft, a plurality of permanent magnets arranged around the shaft in a circumferential direction for permanent excitation and attached to the shaft by an adhesive bond, and a flux conducting device provided for conducting a magnetic flux of the permanent magnets. The flux conducting device has a plurality of soft-magnetic flux conducting elements. Each flux conducting element is placed between two of the permanent magnets and adhesively bonded thereto.
