Dear Friends,

If 60 Hz frequency is used it will be good for speed
related machines as Ns=120*f/P Speed of motors will get
increased.
Considering all eqipments having winding core,its winding
core heating will get increased as Eddy current loss is
directly praportional to frequency & Hysterisis loss is
directly praportional squre of the frequency.
