Title: ELECTRIC MOTOR WITH SIMPLIFIED MOUNTING
Abstract:
An electric motor (100) which has: a stator arrangement (116), a rotor arrangement (140) with a rotor shaft (144) which has a first free shaft end (197) and a second shaft end (196), a bearing tube (190) with a cutout (194) through which during mounting the first shaft end can be introduced into the bearing tube (190), a bearing arrangement (125) which is arranged in the bearing tube and has the purpose of mounting the rotor shaft, a circlip (120) with an annular opening and a slot for permitting widening of the annular opening, which rotor shaft has an annular groove on which the circlip is arranged and which circlip is axially displaceable in the bearing tube between a first circlip stop and a second circlip stop, wherein the first circlip stop is designed to permit the rotor shaft to be slid into the annular opening during mounting, and wherein the second circlip stop bounds movement of the circlip in the direction of the second shaft end, in order to bound movement of the rotor shaft at least in the direction out of the bearing tube.
