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.

Answer / taufic

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.

Hi Baskaran.r!

Dnt give such dumy answers>>>>>>>>.

Answer / virendra

Simple motor speed will be reduced.

I want to ask that is there any relation between current denesity of copper and material purity. also is ther any standard which defines the standard current denesity of material.
