What are Variable Frequency Drives Used For? - NT

Variable frequency drives (VFDs) also referred to as variable speed drives (VSDs), or inverter drives are a type of motor controller used in driving electric motors in varying frequencies and power supply. Although the VFD controls both voltages of power supply to the motor and the frequency, it is regarded as speed control because the result is the modification of motor speed.
