Motor HP Conversion Formula

What would be the typical EFF and PF for motors when doing a conversion? I found this.. but I'm not sure if its valid

1HP=746 watts.

HP=IxVxPFxEFF/746,where PF( Power Factor)=.86 and EFF ( Motor Efficiency)=.81. Using this formula current can be calculated as follows for a 1

Restricting Voltage Fluctuation

In Steel melting or making shop, high current electric electrodes insert into the liquid steel to create arcing to produce special quality steel. Due to this, total system voltage of steel melting furnace is being fluctuated heavily. Many motors or other equipments get burnt or damaged due to this f
