Abstract
A harmonic model of a DC motor drive operating in the continuous current mode fed by a single-phase source is developed. The traditional constant armature current model predicts a square wave line current which has spectral characteristics independent of operation conditions. The electrical equations of the equivalent armature circuit of the DC machine are solved. A Fourier analysis of these equations yields a harmonic model of the motor and drive. The new model is compared to the traditional model in several examples and found to differ greatly at lower values of speed and torque. The new model offers improved accuracy in predicting the harmonic line currents of the 2 pulse DC motor drive.<>
