Abstract

A small commutator motor (1), in particular a blower motor for motor vehicles, has a rotor shaft (2) rotatably mounted in at least one rotor bearing (12) in a motor housing (8, 9). A commutator (18) and an armature winding (21) electrically connected with the commutator (18) are arranged on the rotor shaft (2) so as to be fixed with respect to rotation relative to it. Further, brush guides (11) for receiving brushes (16) held in sliding contact at the commutator (18) and an end shield (10) which fixes the first rotor bearing (12) in place are provided. The end shield (10) and the brush guides (11) are formed as a one-piece structural component part which is a component part of the motor housing (8, 9) as a first motor housing part (8).
