Abstract

A rotor includes a rotor shaft with a mounting portion along a mounting region of the shaft; and a plurality of permanent magnets mounted in the mounting portion on the rotor shaft, wherein the rotor shaft includes, in the mounting portion, a region with a radius reduced with respect to a circular cross-section, such that a radially measured thickness of a permanent magnet is greater in the region than in an adjacent region with non-reduced radius of the rotor shaft.
