Abstract
The invention relates to a method for producing the rotor winding of an electric machine comprising at least four exciter poles in the stator and a commutator rotor with a number of pole teeth which deviates from the number of exciter poles as well as a number of individual tooth coils and commutator segments that is at least twice as large as the number of pole teeth. In order to obtain low torque ripple and a long service life by optimally commutating the coils, a first coil is wound from an initial segment at a selectable offset angle to the initial segment on a first pole tooth, the winding wire is then fixed to another commutator segment at a predefined segment interstice length, whereupon a coil is successively wound from each segment onto the pole tooth having the lowest angular error relative the offset angle in relation to the pole separation of the stator, and the winding wire is then contacted on another segment at the same segment interstice length.
