In slip test, we provide a constant 3 phase voltage across the stator of the machine. Then why does that voltage vary? Its like a variable inductor circuit due to different air gap length but basically if the voltage impressed is kept constant, why does the voltmeter show variation?
Is it like changing the core of the inductor at its steady state. What will happen if I inserted iron core in the inductor when it reaches the steady state in a dc circuit?
