PMG and Excitor In Generators

i want to answer but not after explain what is the meaning PMG? and are you talking about the brush less exciter system or brushes.

exactly sir, its permanant magnet generator and brushless machine

Assuming PMG means "permanent magnet generator", then one can, though the equipment ceases to be called a generator; it is now an 'alternator', and most liquid-fuelled road vehicles have one.

O.k

PMG is a part of magnetic field that is developed by the winding main rotor exciter and it resides in the body of the rotor exciter. because it is iron.in some small generators use in there design small real magnetism on is north and the second is south because the rotor exciter is small size . the explain in this subject is too Long i think what i state is enough

i got it, thanks a lot sir,
