A 220 V, 10 kW, 900 rpm separately excited DC motor has an armature resistance Ra=0.02 Ω. When the motor operates at rated speed and with rated terminal voltage, the electromagnetic torque developed by the motor is 70 Nm. Neglecting the rotational losses of the machine, the current drawn by the motor from the 220 V supply is
