Most industrial processes require rotation of the motors in forward and reverse directions for desired periods. One good example is the automated bottle filling plant. Here the bottles move on a conveyor belt. When the bottles come under the filler, the filler comes down (the motor attached with the mechanism rotates forward) and fills the bottle (the motor stops), then it goes up (the motor rotates in reverse direction) and stops unti […]

The study for the search of renewable sources of energy is now a major concern worldwide as replacement to the high demand of fossil fuels. Majority of the electricity that is generated uses the Faraday's law, the electromagnetic induction. This law led to new technologies that even brought up the misconception of free energy. Energy only becomes free if we don't have to pay for the generation of it; hence we resort to abundant sources […]
ABSTRACT DC motors are widely used in industries because of its versatile characteristics and because of power electronics devices its controlling is becoming sophisticated and precise, but on the other hand because of the power electronics devices power factor and total harmonics distortion problem is becoming more prominent. In this paper DC motor controlled using ATmega8 (AT89C52) microcontroller which is the heart of the system. T […]
ABSTRACT cThe chopper responds by providing variable voltage to the armature for receiving desired speed in accordance with the signal received from controller via firing circuit. There are two controlling loops one for controlling current and one for controlling speed. In this way modeling of separately excited DC motor is done. The model is simulated using matlab after obtaining the complete model of the system. Simulation is done f […]
ABSTRACT DC motors are widely used in industries because of its versatile characteristics and because of power electronics devices its controlling is becoming sophisticated and precise, but on the other hand because of the power electronics devices power factor and total harmonics distortion problem is becoming more prominent. In this paper DC motor control methodology is proposed which includes an Arduino UNO which control dc motor s […]
ABSTRACT Wireless remote controlled dc motor explained in this project. Motor control through RF communication is a very interesting application and is widely used in robotics, electronics toys, automation systems etc. This topic covers the way DC motors can be driven by using the controls from a distant place. The controls are transferred from one end to another by employing an RF signal TABLE OF CONTENT COVER PAGE APPROVAL PAGE […]
