<p>1. A commutator motor of flat construction, in particular for radiator ventilators in motor vehicles, with a rotor set (1) which is supported at one end via a rotor set carrier (5, 6, 8) at a radical distance from the rotor shaft (18), with a rotor winding (7), and with a brush system (9) which projects into the radial gap between the rotor shaft (18) and rotor winding (7), with a commutator (4) which is arranged on the rotor shaft (18) and whose laminations (41, 42) extend into the region of end-face openings (51, 61, 81) in the rotor set carrier (5, 6, 8) beyond the end-face of the commutator hub which faces towards the rotor set carrier, where they are connected to winding head connections of the rotor winding (7) characterized in that a round commutator (4) is provided, having a brush contact surface projecting into the radial gap between the rotor shaft and rotor set, for a radially contacting brush system, and the laminations (41, 42) of the round commutator (4) extend to end-face hooks (43, 44) located in the region of the openings (51, 61, 81), in such manner that during the winding of the rotor winding the hooks (43, 44) can be additionally encased by the winding wire (71, 72).</p> |
