Abstract—
A single-phase induction motor using a new electronically controlled capacitor is described. The system uses a dc capacitor switched by a transistor H bridge. By proper control of the transistor switching, the circuit synthesizes a continuously variable capacitance in series with the auxiliary winding. The system could be used to replace standard single-phase motor capacitor configurations to provide improved ma¬chine performance. Basic system operation, a comparison with conven¬tional motor operation, and illustrations o ....etc

Modeling of Armature Controlled D.C Motor

INTRODUCTION
What is DC Motor?

A direct current (DC) motor is a fairly simple electric motor that uses electricity and a magnetic field to produce torque, which turns the motor.
A dc motor is used to convert electrical energy into mechanical energy for driving loads.



PRINCIPLE OF OPERATION

The operation of a dc motor is based on electromagnetism.

Abstract

Here, the students learn how brushless DC motors have made personal electric vehicles (PEVs) possible, and calculate how much using a PEV instead of an automobile for some of their daily driving can impact their production of carbon dioxide, based on United States driving patterns. In the laboratory, students build a brushless DC motor using three different control methods, based on a reed switch, a Hall effect sensor, and optoelectronics, respectively. In the process, students learn about ....etc

Abstract:
This Project is used to control a single phase Motor from any where in the world through the telephone. The circuit consists of a DTMF tone detector and a powerful 8 bit Microcontroller AT89S52. The Microcontroller senses the DTMF signal through the DTMF decoder IC MT8870 and it switch on/off and speed up/down the motor according to the user need. The circuit has an inbuilt Phone Ring sensor circuit and the system will take over the phone control if it was not taken manually for more than 5 rings.

The DTMF decoder decodes t ....etc

RADIO FREEQUENCY CONTROLLED, ROBOT

DESCRIPTION


A TE trigger the 3encoders are a series of CMOS LSIs for remote control system applications. They are capable of encoding 18 bits of information which consists of N address bits and 18_N data bits. Each address/data input externally trinary programmable if bonded out. It is otherwise set floating internally. Various packages of the 318encoders offer flexible combinations of programmable address/data to meet various application needs. The programmable address/ ....etc

GSM (SMS) Controlled DC Motor
INTRODUCTION
GSM (SMS) Controlled DC Motor is automatic control system which capable of receiving a set of command instructions in the form of Short message service and performs the necessary actions like Start , Stop and speed control. We will be using a dedicated modem/mobile at the receiver module i.e. with the robot it self and send the commands using SMS service as per the required actions.
The mobile unit which is dedicated at the motor driver is interfaced with an ....etc
