Diesel generator is generating power, how is generating, i need step by step, In self excitation how the alternator generates powerin permanent magnet alternator how the power is generated
The principles for power generation are the same for self excitation generation and permanent magnet generation. The only difference is that the self excited is more common and uses an electromagnet that gets power from the power that is generated. The principle is to change chemical energy into thermal energy and into kinetic enery. The magnet rotates inside three coils which induces a current.
magnets move very fast above coils of copper wire beneath it (the coils of copper wire are all attached together and the magnets are moved by a small amount of dc energy) and the current the alternators give off is ac
