Mathematical Model of DC Motor for Analysis of Commutation Processes

The mathematical model of dc motor was created. In model the commutator is approximated by circuit with variable parameters. Extremely different values are assigned to circuit parameters depending on the angular position of the rotor. Model equations were solved using implicit integration method. Commutation processes of dc motor were investigated with the aid of this model. Presented model can be extended and to take into account another phenomena occurring in dc motor.
