Q#1 DC Machines GATE EE 1997 MCQ +2 marks -0.66 marks

A 5kW, 200V DC shunt motor has an armature resistance of 1 ohm and shunt field resistance of 100 ohms. At no-load, the motor draws 6A from a 200V supply and runs at 1000rpm. The rotational loss of the machine is… W and the no load torque is… N-m

Rotational loss = 784 W
No Load Torque = 7.486 N-m

Rotational loss = 884 W
No Load Torque = 7.486 N-m

Rotational loss = 784 W
No Load Torque = 8.486 N-m

Rotational loss = 684 W
No Load Torque = 6.486 N-m
