Question

Example 5.5. A 230 V, 4 pole, 50 Hz, star-connected synchronous motor hos
ra+jx, = 0.6 +j3.0 22 per phase. Its field current is so adjusted that motor draws 10 A at up
from rated voltage source. Now with the field current unchanged, the load on the motor is in-
creased till it draws 40 A from the supply. Find the torque developed and the new pf.​
