(use 2-decimal digits for solutions)

A 6-pole, 500-V. wave-connected shunt motor has 1200 armature conductors and
useful flux/pole of 20 mWb. The armature and field resistances are 0.5 Ω and 250
Ω respectively. What will be the speed and torque developed by the motor when it
draws 20 A. from the supply mains? If the magnetic and mechanical losses amount
to 900 W., find (a) useful torque, (b) output in kW, and (c) efficiency at this load.
