A universal motor has a 2-pole armature with 1020 conductors. When it is operated on load with a.c. supply with an armature voltage of 150, the motor speed is 5400 RPM. The other data is: Input power: 360 W Armature current : 5.2 A Armature resistance: 5.5 Q Compute (i) the effective armature reactance and (ii) maximum value of armature flux per pole.
