ANALYSIS OF SEPARATELY EXCITED DC MOTOR USING MATLAB/SIMULINK

Abstract

High starting and decelerating torque are provided by DC motors in applications that call for rapid stops or reversals. DC motors are well suited for speed control over a large range, which is easily accomplished. In this study, an independently stimulated DC motor is started using three distinct techniques: (i) Increasing the voltage gradually while decreasing it until it reaches a constant value (controlled voltage) (ii) Using a direct starter (iii) Using a step resistance starter to begin. The impact of machine characteristics like rotational speed (ω), armature current (Ia), and torque (Te) on the three (3) approaches will also be examined in this study MATLAB Simulink.
