Experimental based Comparative Analysis and Characteristics of DC Series Motor by using Different Techniques

摘要

In this paper, distinct techniques of speed controlling of a DC motor & its characteristics are discussed. DC series motor control by using resistive controller with and without PLC is proposed. The DC motor has a wide range of speed control, which can be used in robots, drilling, cutting, and household and other occasions. The motor voltage can be changed by inserting a resistor in series with DC motor. In this paper, armature resistive drive control technology and motor control PLC technology are used to control motor speed. PLC is used to control resistance of motor, thereby reducing driving voltage to change the speed. The results confirm the authenticity efficiency of the expected method of controlling motor speed.
