hi all..

duty wood working machinery from US.Most of these involve 3ph,220v,60hz
motors but i need to operate them at 220v,3ph,50hz supply.
can anyone please advice me on what will happen to the production(
efficiency wise.) in this case.
eagerly waiting for ur help..
thnks a ton.

Hi Sam,

bad news:

You would loose 20% in speed. But most important, most of the 60Hz
motors are not build for running permanently on 50Hz (too little iron),
so they will overheat.
Possible solutions: Frequency converter (this way you will have an
electronic speed adjustment) or change the motors.
