Abstract
An electronically commutated internal rotor motor () has an outer stator () and a permanent magnet rotor () arranged rotatably therein by means of a shaft () supported at its drive end () by a rotary bearing () located in the A-side bell () and supported at its other end () by a rotary bearing () located in the B-side bell (). The rotary bearing () in the A-side bell is preferably so configured that it permits a small radial movement () of the drive end () relative to this bell (). The rotary bearing () in the B-side bell () has its outer race () tensioned against a shoulder (). Its inner race () is tensioned between a shoulder () of the shaft () and a shaped part of non-ferromagnetic material. This shaped part is pressed by a countersunk screw (), screwed into a threaded bore () of the other shaft end (), against the inner race.
