Glad to share with you for variable frequency drive(VFD) :

which is also termed adjustable frequency drive,variable speed drive, AC drive,micro drive or inverter drive) is a type of adjustable speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage. 
 
Benefit of VFD:
Energy saving ,Tighten process control, make industry control more easier and Reduce equipment maintenance by installing variable frequency drives (VFDs)
 
Appliances of VFD:
VFDs are used in applications ranging from small appliances to the largest of mine mill drives and compressors. However, about a third of the world's electrical energy is consumed by electric motors in fixed-speed centrifugal pump, fan and compressor applications and VFDs' global market penetration for all applications is still relatively small. This highlights especially significant energy efficiency improvement opportunities for retrofitted and new VFD installations.
If you want to know more about the above information,please do not hesitate to contact me: Mr Showyee Shu
