What are the uses of AC and DC generators?
Basic Uses & Design Typically, AC generators power home electrical appliances and small motors such as juicers, vacuum cleaners, and food mixers. However, DC generators are used to power large electric motors such as those used in subway systems.
What are the uses of DC generator?
Applications of DC Generators
- These generators are used to charge batteries, provide lighting and provide excitation to alternators.
- They are used to provide field excitation current for regenerative braking in DC locomotives.
- They are used in DC motors where speed control is necessary.
What do you mean by AC generator?
alternating current
An alternating current (ac) generator is a device that produces a potential difference . A simple ac generator consists of a coil of wire rotating in a magnetic field. Cars use a type of ac generator called an alternator to keep the battery charged and to run the electrical system while the engine is working.
What is the difference between AC generator and DC generator?
AC generator is a mechanical device that converts mechanical energy into AC electrical power. DC generator is a mechanical device that converts mechanical energy into DC electrical power. In an AC generator, the electrical current reverses direction periodically.
What are the examples of AC generator?
Examples of these include hydropower, fossil fuel-based power, nuclear energy, and solar thermal power plants, among others. Almost all major power plants generate alternating current, as do diesel generators.
Do generators make AC or DC?
Generators are capable of both AC and DC power. Alternators usually are made for A/C (alternating current) applications, hence the name “alternator.” The inherent design differences allow generators to produce immense amounts of wattage per kilowatt and are, therefore, much more substantial.
What is another name for an AC generator?
AC generators are also known as alternators, and are classified according to their rotor construction. Salient pole or projected pole rotors are used for medium speed alternators, operating at around 300 RPM, as found in hydropower plants.
What is an AC generator?
The generated voltage or current is initially alternating one in both the kinds of the generator. The machine which converts the mechanical energy into electrical energy in the output of alternating current or voltage is known as AC Generator. The machine works on Faraday’s law of Electromagnetic induction.
What is an electrical generator?
An Electrical Generator is a machine that converts mechanical energy into electrical energy. This machine is further classified into two other kinds based on the power supply i,e ac and dc. The basic difference name a generator as an ac or dc is its input power supply.
What is the input and output of AC generator?
The AC Generator’s input supply is mechanical energy supplied by steam turbines, gas turbines and combustion engines. The output is alternating electrical power in the form of alternating voltage and current.
What is the use of slip ring in AC generator?
Slip rings are used in AC for the generation of the alternating current in the machine. The generated voltage or current is initially alternating one in both the kinds of the generator. The machine which converts the mechanical energy into electrical energy in the output of alternating current or voltage is known as AC Generator.
