Difference Between DC Generator and Alternator
1. Functional characteristics of DC generator
The DC generator has the characteristics of convenient use and reliable operation, and can directly provide electrical energy for various electrical equipment that requires DC power. However, there is a commutator inside the DC generator, which is easy to generate sparks, and the power generation efficiency is low. DC generators can generally be used as DC power sources for DC motors, electrolysis, electroplating, charging, and excitation of AC generators.
2. Functional characteristics of alternator
An alternator is a generator that generates alternating current under the action of external mechanical force. This type of generator can be divided into a synchronous alternator and an asynchronous alternator.
Synchronous generators are the most common among AC generators. This type of generator is excited by DC current and can provide both active power and reactive power. It can be used to supply power to various load devices that require AC power. In addition, synchronous generators can be divided into four types: steam turbine generators, hydraulic generators, diesel generators, and wind turbines according to the different prime movers used.
