INTRODUCTION
- The speed rotation of machines is totally controlled only by the applied voltage and frequency of the source current. But the speed of rotation of an electrical machine can be controlled precisely also by implementing the concept of drive.
- The systems which control the motion of the electrical machines are known as electrical drives.
- Drive system is widely used in large number of industrial and domestic applications like factories, transportation systems, textile mills, fans, pumps, motors, robots etc.
