In short VFD, is an energy saving device by converting fixed frequency to adjustable frequency to control AC induction motor in variable speed base on the load's changes.
VFD also know as variable speed drive, frequency inverter and adjustable frequency drives. VFD also works as a phase converter to convert single phase input to three phase output in small ratings.
Frequency (or hertz) is directly related to the motor`s speed (RPMs). In other words, the faster the frequency, the faster the RPMs go. If an application does not require an electric motor to run at full speed, the VFD can be used to ramp down the frequency and voltage to meet the requirements of the electric motor`s load. As the application`s motor speed requirements change, the VFD can simply turn up or down the motor speed to meet the speed requirement.
HUAFEI company is expert VFD manufacturer in China, its VFD is mainly used for the machine in coal mine, such as the hoist, belt conveyor, ventilator, water pump etc. Explosion proof type is used under ground with combustible gas and dust. Medium Voltage VFD is mainly used for hoist ventilator or other motor with medium voltage input.
