Energy conservation in industrial A.C drives

ABSTRACT

The induction motors can be considered the larger users of electrical energy. They are used both
in industrial and commercial sectors in a wide range of applications, such as: fans, compressors, pumps,
conveyor, winders, mills, transports, elevators, home appliances and office equipments. In India, the
electric motors used in the industrial field consume typically the 60 to 70% of the total adsorbed
electrical energy. In the commercial secto ....etc

Electrical Drives of Machine Tools
Introduction
The arrangement of the motor nearby the operative member and also the use of variable-speed electric motors make it possible to simplify mechanical transmissions as well as the construction of the machine.
This helps to improve machine-tool design and considerably reduce the physical force required to handle the machine.
Introduction
One or more electric motors driving the operative members of the machine tool make up the machine's essential components.

difference between chopper fed drives and converter fed drives pdf

If the source of supply is d.c. (for example in a battery vehicle or a rapid transit system) a chopper-type converter is usually employed. The basic operation of a single-switch chopper was discussed in topic 2, where it was shown that the average output voltage could be varied by periodically switching the battery voltage on and of for varying intervals. The principal difference between the thyristor-controlled rectifier and the chopper is that in the former the motor current ....etc

CHAIN DRIVES IN LOW TORQUE DRIVES AND REDUCING PULSATIONS
INTRODUCTION TO DRIVES

Mechanical components used for power transmission. It may be belt, chain or gear depending on engine design parameters like - Distance between crankshaft and camshaft, engine maximum speed, engine-torque and engine construction cost. - Power transmission is done from one shaft to another shaft which may or may not rotate at same speed.

Energy is defined as the capacity of a physical system to perform work. In essence, energy is a fundamental quantity that can exist in a range of different forms, most notably heat, light, kinetic, electrical and potential energy. Energy cannot be created or destroyed, but can transition from one form to another. For example, the kinetic (movement) energy from a clap can become sound energy when hands make contact with one another.Energy efficiency refers to the proportion of useful energy that can be converted from a
source into a desired for ....etc

Modern home with optimum energy conservation



ABSTRACT

Now a day s technology increasing rapidly recently it is affecting home needs also. To make normal home to modern home we are introducing some luxury facilities like we can operate any of the electronic devices like FAN LIGHT AC with our T.V remote. For this application we are using AT-mega8 Micro controller which is heart of this project. Fallowing to microcontroller we are also using relays to operate AC appliances.
The Block diagram of the system ....etc
