Speed Control of DC Motor Using Chopper
Kaustubh S. Deshmukh [2] | Rutuja S Hiware
Abstract: The Objective of the paper is to control the separately excited dc motor by using the IGBT based chopper. The speed of separately excited dc motor can be control by varying the armature voltage and varying field flux. Thus the speed can be controlled for under rated speed and speed beyond the rated speed, respectively. In this paper, the motor speed under and upto the rated speed can be achieved by varying the Armature voltage. IGBT based chopper Controls the Armature voltage. The IGBT chopper takes signal from controller and Adjustable voltage is given to the armature of dc motor as per the wanted speed. The advantages to employe this technique is that the Speed varies equivalently with armature voltage and varies inversely with field voltage by keeping field and armature voltage persistent respectively. The IGBT employed chopper i. e. power module gives smoother control as compared with the SCR based circuit. By using this system, we can chop the frequency and speed of DC motor can be control.
