How much energy save vfd if motor run on 50 Hz (full speed)

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.
