Let’s get started with Variable Frequency Drive working, also known as VFD. It is an electronic device that controls the speed of electric motors by adjusting the frequency of the electrical power supplied to them. These drives have become increasingly popular in recent years due to their energy-saving capabilities, improved process control, and reduced wear […]
