Automation
Variable Frequency Drive (VFD)
An electronic motor controller that adjusts supplied frequency and voltage to regulate AC motor speed and torque.
Why it matters
VFDs influence machine speed, acceleration, energy use and motor protection while introducing parameter and stored-energy considerations.
