Separately Excited DC Motor Speed Control Simulation Case Studies

The versatile control features of the DC motor have contributed to the extensive use of the DC motor in the industry. With power semiconductor units are increasingly being used, DC motor speed control is becoming advanced and accurate. The armature voltage can control the speed of the Separately Excited DC motor, using a different single-phase or 3-phase AC/DC converter.This paper presents a modelling of separately excited DC motor speed control using a rectifier controller. The full converter method of the controlled rectifier can help to control the 3-phase output voltage of the controlling speed of the DC motor for a wide range. The system is modelled and simulated to study the speed during the different firing angle of thyristor behaviour. The speed output value was analyzed at different firing angles-the model of the proposed system built in the Simulink bloke simulation software. The simulation and experimental findings are in good agreement.
