Im a beginer here, i just wonder why a generator should always have a DC excitation?
If in transformers dc cannot be transformed (unless its pulsating dc) why is it used in excitation for generators as well. Is it because the magnetic field is moving magnetic one due to it rotates as the prime mover rotates it?
hope someone can share ideas, thanks.
