the pf angle is nothing but angle between voltage and
current and here in induction motor the emf and current are
displaced by 30 and the stator and rotor are displaced by
delta

Calculate torque developed by the 3-phase, 5 H.P., 4 pole induction motor runs at 1500 rpm A 23 N-m B 21 N-m C 10 N-m D 0 N-m
