Draw the circle diagram for a 3 phase 5KW 4 pole, 50Hz, 400V star connected
Induction motor from the following data
No Load test: 400 V, 3.1A, 350 W
Short Circuit test: 52 V, 7.6A, 440W
The stator loss at a standstill is 65% of the total copper losses and the full load current is 7.6A
from the circle diagram determining Power factor , Slip, output , Efficiency.
