What is Variable Frequency Drives (VFD)?

A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter. VFDs are used in applications ranging from small appliances to large compressors. About 25% of the world's electrical energy is used by electric motors in industrial applications. VFDs can reduce energy consumption and improve system performance by matching motor speed to the actual process requirements.
