Question
Three phase slip ring induction motor gives a reading of 65 V across slip rings when at rest with normal stator voltage applied. The rotor is star connected and has an impedance of (0.8 + j6) ohm per phase. Find the rotor current when the machine is (i) at standstill with the slip rings joined to a star-connected starter with a phase impedance of (4+j3) ohms and (ii) running normally with a 5% slip.
