Abstract

A rotor assembly for an electric motor having a rotor shaft and at least one permanent magnet arranged on the rotor shaft. The rotor shaft with the permanent magnet is accommodated in a sleeve the rotor shaft being freely rotatable within the sleeve. The sleeve is closed off by a flange at a first end face. An inner-rotor electric motor having a stator and a rotor assembly of the type described above, with the stator being inserted over the sleeve of the rotor assembly.
