Salient Pole Alternators
Salient Pole Alternators are manufactured either in rotating field or rotating armature type. The laminations are of low loss silicon alloy with high magnetic induction with low magnetizing force. The windings are of good quality super enameled copper wire well impregnated in good quality insulating varnish. The sliprings are of phosphor bronze and the brushes are copper graphite for low wear. The regulation of these alternators are within tolerable limits at different power factors.
Non Salient Pole Alternators
Construction of Non Salient Pole Alternators are as with salient pole type but with distributed windings in both stator and rotor. The regulation of these alternators are within tolerable limits at different power factors.
