Induction Machines
GATE EE 2006
MCQ
+2 marks
-0.66 marks
A 3 phase, 10 kW, 400 V, 4 pole, 50 Hz, star connected induction motor draws 20A on full load. It’s no load and blocked rotor test data are given below:
No Load test : 400 V 6A 1002 W
Blocked Rotor test : 90 V 15A 762 W
Neglecting copper loss in no Load test and core loss in Blocked Rotor test, estimate motor’s full load efficiency
