What is VFD Working Principle? A Complete Guide for 2025
Introduction Variable Frequency Drives (VFDs) have become indispensable in modern industrial and commercial settings. These sophisticated electronic devices precisely control the speed of AC motors by varying the frequency and voltage of the power supplied to them. In this comprehensive guide for 2025, we’ll demystify the VFD working principle, explore its core components, and explain why this technology is revolutionizing energy efficiency across industries. What is a Variable Frequency Drive (VFD)? A Variable Frequency Drive, also known as a variable-speed drive, adjustable-frequency drive, or frequency converter, is a power electronic device designed to control AC motor speed and torque. Unlike traditional fixed-speed motor systems, VFDs allow for dynamic adjustment of motor performance based on actual load requirements.
