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.

(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:

POWER SUPPLY FOR ELECTRIC TRACTION DRIVES
ABSTRACT
Electric Traction
There is a wide variety of electric traction systems around the world, which have been built according to the type of railway, its location and the technology available at the time of the installation. Many installations seen today were first built up to 100 years ago, some when electric traction was barely out its diapers, so to speak, and this has had a great influence on what is seen today.
In the last 20 years there has been a gigantic acceleration i ....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
