The invention relates to a rotor having a short circuit cage and permanent magnets distributed about the circumference, wherein the rotor comprises a core stack extending over the entire rotor region, having longitudinally continuous rotor slots, wherein the short circuit cage draws the rotor slots over the entire length of the core stack, wherein the short circuit cage is designed having cage bars laying in the rotor slots, preferably cast therein, and short circuit rings connecting the cage bars at both end faces of the core stack, wherein the radius of a rotor region is reduced by at least the radial thickness of the permanent magnets. The radius of the rotor (11) is reduced over the entire length between the short circuit rings (17), such that the radial height of the cage bars (15, 29) or cage webs (27) connected thereto is reduced. Permanent magnets (19) are mounted on the rotor (11). The invention further relates to an electric motor having such a rotor, and to a radial pump having such an electric motor. The invention further relates to a method for operating an electric motor having such a rotor, and to a method for producing such a rotor and/or electric motor. |
