Answer / nigam kumar singh

to meet the same load motor will draw additional current,
which can burn its winding ,so over current/overload
protection relay will trip the motor.

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,

Answer / prasad

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

does the power factor of an induction motor improve upon used in parallel with a synchronous condenser , used commonly to provide a leading kva ?
