While it is known to many that an Alternating Currents (AC) generator and Direct Currents (DC) generator are quite different from each other, people do not actually know the actual reasons that separate the two from each other.<\/p>\n
Industrial customers, plant owners and many other employers in the electrical engineering industry should be aware of the differentiating reasons so they will in the future, understand which type of generator to use. By identifying the right type, you will know when is the appropriate time to seek electric generator servicing<\/a> when the time calls.<\/p>\n How It Works<\/strong><\/p>\n AC Generator<\/strong><\/p>\n The magnet\u2019s north and south poles in an AC generator cause the electrical current in an AC generator to flow in the opposite direction, converting mechanical energy<\/a> into AC electrical power.<\/p>\n DC Generator<\/strong><\/p>\n Unlike AC generators, the current that flows through the coil, revolves in a fixed field, with both ends of the coil being attached to a commutator. The purpose of the commutator is to balance the charges leaving and re-entering the generator, to create a current that flows in a single direction.<\/p>\n Efficiency Of Brushes<\/strong><\/p>\n AC Generator<\/strong><\/p>\n This type of generator has slip-rings and with its smooth and steady surface, it ensures that the brushes are always kept in contact with the slip ring surfaces.<\/p>\n To put it simply, it is the main reason why brushes have a longer life and higher efficiency as they do not deteriorate at a fast rate and the chances of a short circuit are extremely low with slip-rings being present.<\/p>\n
