Method for producing the rotor winding of an electrical machine, and an electrical machine with a rotor winding which is produced in accordance with this method

Abstract

The invention relates to a method for producing the rotor winding of an electrical machine having at least four exciter poles in the stator () and having a commutator rotor () with a number of slots (N) and pole teeth (Z) which deviates from the number of exciter poles, and having a number of individual tooth coils (S) and laminations (L) which is at least twice as high as the number of pole teeth, wherein the individual tooth coils are wound, starting from the first coil (S) onto in each case that pole tooth with the lowest angular error (Wf) in relation to a pole division (Pt). In order to permit non-critical guidance of the winding wire () in the region of the lamination connections, provision is made, at least in the case of a last-wound section (B) of the coils (S), preferably in the case of all of the coils, for the winding wire (), with which contact is made by a lamination (L) in each case between two coils (S), to be fed from one side of the lamination (L) and guided away from the other side, and for at least one pole tooth (Z), but at most two pole teeth (Z) to be situated between the slot (N) from which the winding wire () of the lamination (L) is fed and the slot (N) at which said winding wire is guided away from the lamination (L).
