Nowadays, fractional horsepower commutator motors are produced and tested in highly automated manufacturing lines. During their production, winding insulation damages and wrong connections between commutator bars and armature coils can occur. Often, the currently used testing techniques can not reliably detect faults in early stages. Therefore, it is necessary to make detailed investigations about these faults and their consequences. Within this work, characteristic armature faults are modeled, which consider effects at low and high frequencies. According to these improved fault behavior prognoses for commutator machines, it is possible to develop more efficient diagnostics methods.
