IF MOTOR IS RUNNIG SO AT 60 HZ -SPEED OF MOTOR IS RISE
BECUASE OF N=120F/P ALSO ITS IRON LOSSES OF MOTOR IS
INCREASE.

Answer / neeraj katoch

simple if frecuncy is increse the speed of motor is also
increse and vise visa and resulted motor may be burn out

Answer / santosh kawade

If we increase only frequency of motor and keep voltage
constant as a rated voltage then speed of motor will
increase but maximum torque capacity of motor will reduce.

Answer / stalin raj

The motor will run at a speed corresponding to
Ns=120f/p.Due to this high speed the bearings and the
winding insutions get didturbed an the motors get defective.

Answer / qamar

motor works on v/f=constant, if frequency is increased we
have to increase voltage for satisfactory opearation.
