External rotor motor, particularly a small motor or a micromotor.

摘要

External rotor motor comprising: an inner stator (22) which has a stack (23) at least in regions is provided with a coating (76), wherein the inner stator (22) having an inner recess (36 ); an outer rotor (42); a tube (38) bearing support, which on its inside has a bearing arrangement for supporting the outer rotor (42) and which on its outer face (98) has grooves (102) guide; one washer (20) as ring attached in the coating (76) of the laminations (23), disc at least in its inner circumference (48) is provided with several projections (34) which inwardly fit into the inner recess (36) of the inner stator (22) and which are guided in the guide slots (102) of the tube (38) bearing support, wherein the width of at least part of the projections ( 34) that fit into the inner recess (36) essentially coincides with the width of each guide groove (102) associated under the tube (38) bearing support, wherein at least one of the projections (34) this It designed so that during assembly inner stator displacement (22) and tube (38) bearing support it is bent and in this position folded into the guide groove (102) associated engages the outer face of the tube ( 38) bearing support as a contragancho (34 '') and so as egura the inner stator (22) against extraction of the tube (38) bearing support.
