Answer / mehul bhoraniya

it was burnt after some time, cause of more current flow in
this two phase. that's condition known as "single phasing"

Answer / ken shirke

This condition is called single phasing.In this case motor
draws more current from remaining two supply lines.Torque
developed is reduced since T is directly proportion to
v2.There will be a sever vibration.Motor will run if load
is small.

Answer / jayakrishnan

Motor will run as usual with some extra vibration, but the thing is that you can run the motor only with 60% of its rated, as told above the speed will not be reduce unless frequency reduces, its all slip maters,

It dosen't work

Answer / sandeep

motor runs at lower speed(means working for low load) and
the no of poles generated in rotor also changes
