How vfds work ?
VFD is short for "Variable Frequency Drive".It is a type of motor controller that drives an electric motor by changing the frequency and voltage supplied the electirc motor.We also call them,Variable speed drive, adjustable frequency drive,ac drive,frequency inverter , adjustable speed drive,and ac inverter.
Frequency(Hertz) is directly related to the motor's speed.In other words, the motor will run at faster speed when higher frequency .If the load does not require the electric motor to run at full speed,VFD can be used to ramp down the frequency and voltage to meet the requirements of the motor's load.
