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.

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. I ....etc

mechanical energy into electrical energy

INTRODUCTION
In this model we show that how we can generate a voltage from the busy traffic. Conversion of the mechanical energy into electrical energy is widely used concept. It’s a mechanism to generate power by converting the potential energy generated by a vehicle going up on a speed breaker into rotational energy. We have used that simple concept to the project. We connect one mechanical rod with the dynamo and fit this rod on the surface of the ....etc

(1)Power modulator:
Resistance controllers
Eddy current drive
MG set
The function of the power modulator is to change the electric energy of the source as per load torque speed characteristics.
(2)Control circuit:
The function of control circuit is to control - the speed, starting characteristics and braking characteristics
(3)Motor:
The motor can be ac or dc, as per the application of use of the drive.
(4)Sensing unit:
....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 spe ....etc
