Calculate the fullload phase current drawn by a 440 Vms 20ho

Calculate the full-load phase current drawn by a 440 V(ms) 20-ho (per phase) induction motor having a full-load efficiency of 86 % and a full-load power factor of 76%. 40 60.3 46.8

Solution

given per phase hp so calculate current for single phase

current=(746*hp)/(voltage *pf*eff)

I = (746*20)/(440*0.86*0.76) = 51.88
