Introduction
Generator – The mechanism of action of the generator can remain expressed as a device that moves magnets near a wire to create a continuous flow of electrons. It works because of the relationship between magnets and electricity, where the generator consists of a series of isolated coils of wires, which form a fixed cylinder. This cylinder surrounds a rotating electromagnetic column.
When this electromagnetic column rotates, it induces a small electric current in each part of the wire file. Each piece of the wire coil forms a small separate electrical conductor. Then small winds from the difference parts gather, including a large current. This current represents electricity that travels through power lines from generators to generators. Consumers.
Mechanical Power Sources for the Generator
The mechanical energy required to operate the generator can usually remain obtained from a rotational column, which is equal to the torque of the column multiplied by rotational speed or angle, and mechanical power can be obtained from several sources, including hydraulic turbines in dams or waterfalls, wind turbines, steam turbines that use steam generated by heat from fossil fuel combustion, nuclear fission, gas turbines burn directly into turbines, gasoline engines, and diesel.
And there are many sources of mechanical power, such as hydraulic turbines in dams or waterfalls, wind turbines, steam turbines that use steam from burning fossil fuels, or from nuclear fission, gas turbines where gas is burned directly into turbines, diesel or gasoline engines. The structure and speed of the generator vary depending on the mechanical characteristics of the main engine.
History
in 1831, scientist Michael Faraday discovered the generator, a machine used to change mechanical energy to electric power, which operates on electromagnetic induction. When a conductor passes through a magnetic field, the stimulating voltage across both ends of the conductor transmits this electricity.
It distributes it through power lines to local, commercial and industrial customers. Genes produce the necessary electricity for cars, aircraft, ships, and trains. All generators are currently the provider of alternating current power grids, reversing polarity at a fixed frequency, usually 50 or 60 cycles. Since several generators remain connected to an electricity grid, they must then operate at the same frequency for a simultaneous generation.
Principle of Generator Work
Generators are an essential part of the components of many devices in our lives, such as washing machines, vacuum cleaners, etc. They can remain operates in two different modes i.e. can use as an engine that moves the device in one direction and as a generator.
The mechanism of the generator’s work depends on electromagnetic and energy conservation significantly. Where the electric magnet is the essential part of the generator. But control its magnetic power through electricity. When a wire made of a conductive material such as copper moves through a magnetic field, the current arises in the wire that is a generator.
Primitively, but when electricity passes through the wire wrapped around an iron heart in a magnetic field. It moves and is, in this case, a primary engine.
Generator Components
The Generator Consists of Four Main Components:
Rotor: is an exposed wire base mounted on a column. The hard part: a field of electric power-stimulating magnets is arrayed next to each other inside the lid.
Sliding rings: they carry ac to and from the engine.
Brushes connect to slip rings and transport the current to and from the electric circuit. Generators remain classified into two types based on the resulting electric current. They are alternating current (AC) or direct current (DC).
It should remain noted that the two types operate in the same basic principle despite different construction details for each. The generators are classified according to the mechanical power source or the main engine employed by the generator. Such as water or steam power.
