Abstract: A possibility has been found for determining the resistances in a loop that cannot be disconnected, by measuring with an ohmmeter. Such loops form the rotor windings of collector motors. To showcase the method, a fictitious example with a small number of collector plates has been described. The method has been applied by studying a motor for a mine locomotive DRT – 10A2 with 105 collector plates. The resistances of the sections of the wave winding have been determined.
Key words: DC motor, rotor, sections, windings
