Answer Posted / rahul
of course it will not run..coz an AC motor(sync or ind)
needs rotating magnetic field which is possible to get only
if dc supply is rotating. Sync motor has arm on stator. So
no rotating field. And induction m/c run on Electromagnetic
induction principle which is not possible with dc coz ckt
saturates in dc(similar to transformer). So there can be
heavy heating followed by damage;
