The worse armature reactive amper turns
WebFor all d.c. shunt generators, the terminal voltage decreases as the machine is loaded for the following reasons: 1 The e.m.f. generated is reduced due to the effect of armature reaction which causes magnetic saturation at one of the pole tips and hence a reduction in the flux per pole. 2 The armature windings have resistance. 3 WebThe effects of Armature Reaction are as follows:- Because of the armature reaction the flux density of over one-half of the pole increases and over the other half decreases. The total flux produces by each pole is slightly less …
