Answer Posted / hansraj
the dynamical induced emf needs a constant flux i.e time
invarient flux
if we give the ac input it produces alternating flux in the
rotar field and dc current not producec e.m.f. is induced
so the
electrical power will be zero

What will be the impact on motor performance if a LT motor is rewound with changed motor winding data as given below:- Original winding data: total 04 wires = 02 wires of 17 SWG + 02 wires of 16.5 SWG. Changed Winding data: total 03 wires of 15.5 SWG wire size Motor rating: 160KW, 740RPM, 415V, ID FAN application. Normal Running Current = 95% of FL Current.
