(b) A de shunt machine ( 10 kW, 250 V, 1200 rpm) had armature resistance of 0.25 N. The machine is connected to 250 V dc supply, draws rated armature current ad rotates at 1200 rpm i. Determine the generated voltage, the electromagnetic power developed and the torque developed. ii. The mechanical load on the motor shaft is disconnected, and the motor draws 4 A armature current, determine the speed and rotational loss (Ignore armature reaction)
