This work is presenting en electrical driving system equipped with independent excitation D.C. motor. The mathematical pattern of the electrical driving system has been established and its Simulink pattern has been made. The electrical driving system with D.C, motor has been analysed in the case when the useful resistant torque produced by the load is constant. The variation diagrams of the current and angular speed during the start-up transient duty of the electrical driving system have been drawn out.
