Abstract
A method of rapidly assembling the rotor () of an external-rotor motor () onto a bearing support tube () and in a predetermined axial position relative to the latter, includes the steps of: beginning at a rotor cup portion () of the rotor (), mounting on a rotor shaft (): a compression spring (), a retaining washer (), and a plurality of rolling bearings (); then pressing into the bearing support tube (), by means of a pressing-in force (K), the rotor (), with the elements mounted thereon, the compression spring () being compressed so that the rotor cup presses the washer () into the tube (); subsequently removing the pressing-in force (K), and displacing the rotor shaft () by means of the compression spring () within the bearings () so that the rotor () assumes the desired predetermined axial position, relative to the tube ().
