What is Variable Frequency Drive (VFD)?

A Variable Frequency Drive (VFD) (also known as AC Drive, Inverter, Adjustable Frequency Drive, Adjustable Speed Drive, Variable Speed Drive Or Variable Frequency Variable Voltage Drive) is a type of equipment used in electro-mechanical drive systems to control & manage motor speed and torque by altering motor input voltage and frequency.
