Zusammenfassung:The invention relates to a direct current motor and a method for producing the direct current motor. The direct current motor (1) is equipped with a permanent magnetic inner rotor (2) rotatably mounted about a motor longitudinal axis (19), a wound stator core (3) with protruded inward poles (4) which are connected in the circumferential direction with a return ring (5) in one piece and separated from one another by stator grooves (6), and an insulating body (7) which lines the stator grooves (6) and has a return ring cover (8) which is formed with axially parallel projections (9) and which covers an axial end face of the return ring (5), wherein a winding wire (10) is wound around one pole (4) and is guided around two projections (9) radially on the outside to the spatially adjacent pole,each pole being assigned a projection (9). The object of the invention is to provide process-reliable manufacture, simple assembly and good efficiency in a generic DC motor.
