Actually electrical machines can with stand fluctuations in
frequency in cirten limits according to the manufacturer
design.if decided to give more than the limits the rpm of
the machines increased normally.according to machine rating
the stator core and insulation of the winding designed due
to this high frequency the eddy currents induced in the
stator core more than the rating.due to this currents
abnormal heat (i2r)generated due to this the insulation of
the winding damaged and winding will be shorted.
