This paper x-rays the workability of a direct current(DC) electric motor speed control via a 3- Φbridge thyristor rectifier. The devices are applied to control the given power so as to check the speed of the DC motor. The gadgets are inserted on a heat sink to lower the heat ratio of the semi-conductor for effective running and good performance of the system. Armature Voltage Control method is applied in this study where the voltage supplied to the winding of the armature of the D.C motor is checked to alter the velocity of the direct current motor. The model of mathematics is utilized to design a D.C. motor that is separately excited whose rating is 5HP (3.78kW), with a voltage of 240V and speed of 1750 rpm. MATLAB Simulink software is used for the analysis and simulation. Speed of the Armature voltage is checked using different 1-ΦAC/DC converters such as half converter, semi converter, full converter and dual converter thyristor-based circuits for speed control of the DC motor. This is actualized through the use of power semi-conductor devices. Conclusively, the study carried out showed that a thyristor can be used in controlling the speed of a direct current motor.
