What is VFD variable frequency drive

Question

Accepted Answer

A VFD is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the motor.

VFDs are used to control the speed and torque of AC induction motors.
They are commonly used in HVAC systems, conveyor belts, pumps, and fans.
VFDs can improve energy efficiency by adjusting motor speed to match the load requirements.
They can also provide soft start and stop functions to reduce mechanical stress on equipment.
Example: Using a VFD to control the speed of a conveyor belt in a manufacturing plant.
