STEAM TURBINE
1. INTRODUCTION
A steam turbine is a mechanical device that extracts thermal energy from pressurized steam, and converts it into rotary motion. Its modern manifestation was invented by Sir Charles Parsons in 1884.

DC GENERATOR

Presented by,
KAVYASHREE. S



INTRODUCTION TO DC GENERATOR


An dc generator is a machine which converts mechanical energy or power into electrical energy.

WORKING PRINCIPLE

It is based on the principle of production of dynamically induced e.m.f. (electro motive force). Whenever a conductor cuts magnetic flux, dynamically induced e.m.f is prodused in it according to Faraday’s Laws of Electro magnatic Induction. This emf causes a current to flow if the conductor circuit is clos ....etc

ABSTRACT:

Power—from the design perspective, less is more but too little is never enough. We live in a power-constrained world. Battery-powered systems may be the most talked about, but the power problem is everywhere—from kilowatt-rated industrial motors to mobile phones to sensor-activated devices that wake up once a week to send telemetry data. Energy consumption in the United States alone is forecast to increase by 32 percent by 2020. This appetite for power places a serious strain on natural resou ....etc

Abstract:
Conserve Energy is the mantra for engineers. Machine design plays a vital role in energy conservation and we have designed a new theoretical machine called ËœMotaratorâ„¢ performs the function of D.C motor and gets 50 to 70% of energy from the inbuilt D.C.generator.ËœMotaratorâ„¢ is similar in construction to that of the D.C. motor in the stator side (poles). The armature of the ËœMotaratorâ„¢ has two types of winding .One for the motor; which is in the outer periphery of the armature and the ....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.

CAMLESS ENGINES A NEW APPROACH IN I.C.ENGINES
internal combustion comprise the valve train hardware . In the camless valvetrain, the valve motion is controlled directly by a valve actuator there's no camshaft or connecting mechanisms. Various studies have shown that a camless valve train can eliminate many otherwise necessary engine design trade-offs.Automotive engines equipped with camless valvetrains of the electrohydraulic and electro-mechanical type have been studied for over twenty years, but produc ....etc

INTRODUCTION TO AMMONIA
________________________________________

Ammonia is one of the most important basic chemical of the world, ranking with materials such as sulfuric acid and sodium carbonate. In the fertilizer field, anhydrous ammonia itself has become the major supplier of the fertilizer nitrogen in India and it is also important inter mediate in production of more complex chemicals.
The major use of ammonia, both directly and indirectly, is as an intermediate in the fertilizer area. There are many othe ....etc

GENERAL INFORMATION
Ammonia is a compound of nitrogen and hydrogen with the formula NH3. It is a colorless gas with a characteristic pungent odor. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceuticals. Although in wide use, ammonia is both caustic and hazardous. In 2006, worldwide production was estimated at 146.5 million ....etc

SPEED SENSORLESS SEPARATELY EXCITED DC MOTOR DRIVE WITH AN ADAPTIVE OBSERVER


ABSTRACT
This project deals with a speed sensorless separately excited dc motor drive which uses the adaptive observer to estimate the rotor speed. The stability analysis of speed estimation is carried out. The modified feed forward control is integrated with the adaptive observer to simplify the implementation. The design guideline for feedback gain and the speed controller are also given to assure system stability for the entire oper ....etc
