A generator is a device that converts mechanical energy into electrical energy.
The reverse conversion of electrical energy into mechanical energy is done by a motor, motors and generators have many similarities. A generator forces electric charges to move through an external electrical circuit, but does not create electricity, is already present in the thread of its windings. It is similar to a water pump, which creates a flow of water, but does not create water inside. The mechanical energy source may be a reciprocity or the steam turbine, the water falls through a turbine or waterwheel, an internal combustion engine, a wind turbine, a hand crank, air or any another source of mechanical energy. For more information see electric generator sales.
The operation of power generators are based on the phenomenon of electromagnetic induction: When a conductor moves relative to a magnetic field, voltage is induced in the conductor. In particular, if a magnet is spinning inside a coil, the AC voltage is induced in the coil. For more information, see how electric generators work
The induced voltage (called electromotive force or emf) will create a current through an external circuit connected to the coil, resulting from the energy delivered to the load. Thus, the mechanical energy that rotates the magnetic field source is converted into electrical energy. Note that the load current in turn creates a magnetic field that opposes the change in the flow of the coil, the coil which opposes the motion. The higher the current, the greater the force to be applied to the magnet to avoid slowing down. In practice, the magnetic field is most often induced by an electromagnet instead of a permanent magnet. In AC systems, usually the magnet is spinning and producing power of the armature is stationary. The armature usually consists of a set of coils that form a cylinder. The electromagnet consists of so-called field coils mounted on an iron core. A flow of current in the coil field is required to produce the magnetic field. This current can be obtained from an external source or from the armor of the system itself.
Most modern sources of alternating current coils are self-exciting field: the field coil current is supplied by an exciting additional settlement in the armor. The initial magnetic field is produced by the residual magnetism in the cores of the electromagnet. When the engine starts first turn in the armor, at first the armature rotates in a very weak magnetic field and produces small fem. This emf generates a current in the field coils, which increases the magnetic flux, which in turn increases the EMF in the armature. This process continues until the nominal output voltage is reached. If the core of the electromagnet lost its residual magnetism, the rotor rotation, but not the output voltage is produced. In this case, to start the device may have to field calls flashing.
Portable generators are designed for use with devices with wires attached to them. May be especially suitable for use in remote locations such as campsites and construction sites. Lights, small appliances, etc. can be connected directly to portable generators. In general, they are not designed to be connected to your home or any building wiring. Do not attempt to install these dipositive personarlmente your electrical panel.
In general they are directly connected to building wiring to provide backup power during emergencies and power outages. However, the wiring must be properly installed by a qualified.
Properly installing a "permanent" of the generator is very dangerous. If you have this type of generator installed, you need a permit.
With so many applications, power generators are increasingly used as portable power sources and emergency-proof safe. Electric generators are used in different places, including mobile power source of origin, property, houses that do not require secure energy, which includes casinos and hospitals, and even government properties like dams and nuclear plants, although the latter places great power generators use much more expensive.
Power generators are great products to help maintain electricity in homes during extended outages. You can keep the whole house powered or just certain appliances like home appliances, refrigerators and freezers. Casinos use high-powered electrical generators to keep all slot machines and power equipment, and hospitals must have high-powered generators to keep critical medical machines running. Government offices use backup generators powerful to guarantee all the necessary places. Now that some of the useful applications of electricity generators have been presented, to discover the types of electrical generators.
When purchasing a generator backup, be sure to accurately measure the amount of power required to drive the implementation, because they mistakenly sizing energy needs could cause serious problems. There are many types of electric generators of security for all applications, locations and power levels. There are many different brands of big names that stand out in Genergy and Taigu, different types of electrical backup generators, including natural gas, diesel, propane, gasoline and many other different generators with different power and security systems .
