Home » Electrical Machines » Electrical machines miscellaneous » Question

If rotor power output of 3-phase induction motor is 15 kW, then rotor copper losses at a slip of 4% will be _______ W .

1. 300 W
2. 340 W
3. 600 W
4. 1000 W

Correct Option: C

Rotor copper-loss = sP_G = (0.04) × 15000 = 600 W
