vfd means varriable frequency drive also known as
vsd,inverter,vsvf drive means it is a electronics device
based on volt/hz ratio.
f=N*p/120 means if u will varry the frequency the rpm will
also varry. thus P= 1.73*VI COS PHI IF THE device getting
less current the power also dawn and unit also decrease
hence the power will save
