induction motor. we have a three phase supply from
diffrent source like R= transformer.
Y = DG sets.
B = ups.

if motor is runing.

Answer Posted / tom mathew

motor will not run because the 3 phases RYB shoud be of
same frequency. We should synchronize the phase frequency
before connecting. It is not possible too. So it will
vibrate but doesnt rotate.
