Hi,
Normaly the motors will design for 4 Poles:-
W.K. That N=120f/P
If the motor is designed to operate on 60HZ its speed will
be 1800RPM,
If you operate the same motor on 50Hz Supply,then its speed
will reduced to 1500 RPM...

Answer / baskaran.r
when operating 50 hz the important change is voltage. we are
to make V/F as constant ie voltage /frequency equal there
fore to operate the motor in 50 hz we have to reduce the
voltage per v/f calculation. if operated with same voltage
the flex will saturate and motor will take high amps and
burn the speed will reduce to 1500 as stated.

Answer / tareq harb
simply it will run on speed lower than rated speed of
course if there is no under speed protection installed, if
so it will not work.

Motor will run on low speed compared with 60hz frequency.
Normaly the motors will design for 4 Poles:-
Speed of Motor =120f/P
If the motor is designed to operate on 60HZ its speed will
be 1800RPM,
If you operate the same motor on 50Hz Supply,then its speed
will reduced to 1500 RPM...

Answer / parth rawal
if motor designed at 60hz & operated on 50hz then the required
output which is desired will not get poor efficiency & regulation speed will increses

Answer / nagaraju chikkala
If we operate like this, we can't get designed torque becoz v/hz ratio will be more than design v/hz ratio.
If we want to operate with 50 hz, we need to reduce the voltage as design v/hz ratio.
