Rotor for an electric motor, electric motor and method for its production

摘要

The rotor (100) has a rotor assembly (20) attached on a rotor shaft (10) having a rotor facing surface formed with metal sheets. Each metal sheet includes a contour having a central recess transverse to an axis (A) of the rotor assembly, where the contours of the metal sheets are arranged non-congruent to each other. A permanent magnet is arranged in a receiving opening formed in the rotor assembly. An independent claim is also included for a method for manufacturing the rotor.
