Abstract:
1. A method for producing a rotor winding of a direct current motor having at least four exciter poles in the stator and having a commutator rotor, the commutator rotor including a number of slots and pole teeth on its circumference, the number of pole teeth deviating from the number of exciter poles, and having a number of individual tooth coils and an equal number of commutator laminations, the number of commutator laminations being twice the number of pole teeth, the method comprising: continuously winding the individual tooth coils onto the pole teeth so as to be evenly distributed, wherein the continuously wound coils are wound starting from a first coil onto in each case that pole tooth with the lowest electrical angular error in relation to a pole division; causing the individual tooth coils to contact connection lugs of the commutator laminations with a predetermined lamination interstice length, the predetermined lamination interstice length ensuring that an end of each coil is contacted to a free lamination; wherein continuously winding the individual tooth coils comprises feeding a winding wire from one side of the commutator lamination and guiding the winding wire away from the other side, wherein at least one pole tooth and at most two pole teeth are situated between the slot from which the winding wire of the lamination is fed and the slot at which said winding wire is guided away from the commutator lamination; wherein the individual tooth coils are continuously wound in succession, the winding wire is led from the coil to the lamination, and then from the lamination to the coil, in each case between two pole teeth of the number of pole teeth situated closer to the lamination so that at most two pole teeth are situated between the lamination and the feed through of said winding wire.
