What is a Variable Frequency Drive?
A Variable Frequency Drive (VFD) is a device which is used in a system that has an AC motor, Operator Interface and Controller Assembly. It is also called as Adjustable Speed Drive (ASD) or Inverter Drive.
In other words we can say that a Variable Frequency Drive is a device that controls the speed and also the torque of the AC motor by changing the frequency and voltage of the supply. We can also use VFD to Start, Stop and also control the motors speed.
The usage of VFDs has increased the performance of the work in many industries. It works on the principle of a three-phase induction motor. The benefits of using VFD are
- It improves the in controlling the process in a good manner.
- As we can control the speed, so we can save energy and power.
- We can save the resources that are being used.
Variable Frequency Drive
Variable Frequency Drive (VFD) is the type of AC motor drive that controls the speed and the torque. It can control the speed by changing the frequency of the current. They can also control the speed and torque of the motor by changing the voltage. They are the motors of the modern world. Most industries are now shifting to use VFD as they are easy to use and can be controlled by software. VFDs are not only used in large-scale industries but also used in small-scale industries as well.
