Answer Posted / nagaraj
VFD stands for variable frequency drive.Change in frequency changes the RPM , which is directly proportional.
Synchronous speed = 120 x f/p
Here 120 is constant, f stands for frequency and p for no. of poles. The operating frequency in INDIA is 50 Hz.
Operating frequency is set at 50Hz, motor runs at rated speed, so no savings in power consumption.
