Abstract
A method is provided for manufacturing a rotor () of an electric motor. The rotor () has a rotor shaft (), inner sheet metal packets (), outer sheet metal packets (), buried magnets () arranged in the assembled state between the inner sheet metal packets () and the outer sheet metal packets (), and surface magnets () arranged in the assembled state on the outer sheet metal packets (). The method includes pushing the inner sheet metal packets () onto the rotor shaft () to achieve alignment rectangularly and coaxially. The rotor () is constructed by placing the buried magnets () and the outer sheet metal packets () on the inner sheet metal packets () and the surface magnets () on the outer sheet metal packets (). A total run-out of the rotor () thus is set to a predetermined acceptable amount.
