-0.66 marks
A 440 V, 50 Hz, 6 poles and 960 rpm star connected induction machine has the following per phase parameters referred to the stator:
The magnetizing reactance is very high and is neglected. The machine is connected to the 440V, 50 Hz supply and a certain mechanical load is coupled to it. It is found that the magnitude of the stator current is equal to the rated current of the machine but the machine is running at a speed higher than its rated speed. Find the speed at which the machine is running. Also find the torque developed by the machine.
