Answer Posted / ranjit kumar mallick
It is quite difficult to provide three phase supply to a
rotating object like rotor.As you know in case of squirel
cage motor the rotor is shorted through end rings so
breaker will trip once you give supply to shorted motor.In
case you open circuit the rotor winding and then you give
three phase supply but you have check the phase squence of
stator and rotor to make the stator magnetic field follow
the rotor magnetic field.Initially the motor will start
with very high torque but afterwards it will become very
messy to calculate the load current, voltage etc due to the
effects of faraday and lenz law and the behavior becomes
unpredictable. I will sugest not to make such
experiment.Any way the three phase slip ring is mostly
unavailable to make this experiment.
