Model of pulsating current traction motor taking into consideration magnetic losses in steel

Abstract

Mathematical modeling of electromagnetic processes in a traction motor of pulsating current is applied taking into account the nonlinear nature of the armature inductance, the inductance of the excitation winding and the nonlinear nature of the universal magnetic characteristic. The magnetic losses in the steel of the traction motor were taken into account by establishing the dependence of these losses on the frequency of reversal, The magnetic flux in the magnetic circuit of the motor and the geometric dimensions of the motor.
