In , a generator is a device that converts into for use in an external. Sources of mechanical energy include , , , and even hand. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist. Generators provide nearly all of the power for. The reverse conversion of electrical energy into mechanical energy is done by an , and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity and frequently make acceptable manual generators. Early Generator in , , Electromagnetic generators fall into one of two broad categories, dynamos and alternators. The magnetic field of the dynamo or alternator can be provided by either wire windings called or. Electrically excited generators includes an to control the field winding flux. A generator using PMs is sometimes called a , or PMSMs. In a generator, alternator, or dynamo the armature windings generate the electric current, which provides power to an external circuit. The armature can be on either the rotor or the stator, depending on the design, with the field coil or magnet on the other part. Before the connection between and was discovered, were invented. They operated on principles, by using moving belts, plates, and disks that carried charge to a high potential electrode. The charge was generated using either of two mechanisms: or the. Such generators generated very high and low. Because of their inefficiency and the difficulty of machines that produced very high voltages, electrostatic generators had low power ratings, and were never used for generation of commercially significant quantities of electric power. Their only practical applications were to power early , and later in some atomic. Faraday disk generator Main article: The operating principle of electromagnetic generators was discovered in the years of 1831—1832 by. The principle later called , is that an is generated in an electrical conductor which encircles a varying. He also built the first electromagnetic generator, called the ; a type of , using a disc rotating between the poles of a horseshoe. It produced a small. This design was inefficient, due to self-cancelling counterflows of in regions of the disk that were not under the influence of the magnetic field. While current was induced directly underneath the magnet, the current would circulate backwards in regions that were outside the influence of the magnetic field. This counterflow limited the power output to the pickup wires, and induced waste heating of the copper disc. Later homopolar generators would solve this problem by using an array of magnets arranged around the disc perimeter to maintain a steady field effect in one current-flow direction. Another disadvantage was that the output was very low, due to the single current path through the magnetic flux. Experimenters found that using multiple turns of wire in a coil could produce higher, more useful voltages. Since the output voltage is proportional to the number of turns, generators could be easily designed to produce any desired voltage by varying the number of turns. Wire windings became a basic feature of all subsequent generator designs. Jedlik and the self-excitation phenomenon Independently of Faraday, the Hungarian started experimenting in 1827 with the electromagnetic rotating devices which he called. In the prototype of the single-pole electric starter finished between 1852 and 1854 both the stationary and the revolving parts were electromagnetic. It was also the discovery of the principle of dynamo , which replaced permanent magnet designs. He also may have formulated the concept of the in 1861 before and but didn't patent it as he thought he wasn't the first to realize this. Direct current generators This large belt-driven high-current produced 310 amperes at 7 volts. Dynamos are no longer used due to the size and complexity of the needed for high power applications. A coil of wire rotating in a magnetic field produces a current which changes direction with each 180° rotation, an AC. However many early uses of electricity required DC. In the first practical electric generators, called , the AC was converted into DC with a , a set of rotating switch contacts on the armature shaft. The commutator reversed the connection of the armature winding to the circuit every 180° rotation of the shaft, creating a pulsing DC current. One of the first dynamos was built by in 1832. The was the first electrical generator capable of delivering power for industry. The of 1844, now in , is the earliest electrical generator used in an industrial process. It was used by the firm of for commercial. The modern dynamo, fit for use in industrial applications, was invented independently by , and Samuel Alfred Varley. Varley took out a patent on 24 December 1866, while Siemens and Wheatstone both announced their discoveries on 17 January 1867, the latter delivering a paper on his discovery to the. Wheatstone's design was similar to Siemens', with the difference that in the Siemens design the stator electromagnets were in series with the rotor, but in Wheatstone's design they were in parallel. The use of electromagnets rather than permanent magnets greatly increased the power output of a dynamo and enabled high power generation for the first time. This invention led directly to the first major industrial uses of electricity. For example, in the 1870s Siemens used electromagnetic dynamos to power for the production of metals and other materials. The dynamo machine that was developed consisted of a stationary structure, which provides the magnetic field, and a set of rotating windings which turn within that field. On larger machines the constant magnetic field is provided by one or more electromagnets, which are usually called field coils. Large power generation dynamos are now rarely seen due to the now nearly universal use of for power distribution. Before the adoption of AC, very large direct-current dynamos were the only means of power generation and distribution. AC has come to dominate due to the ability of AC to be easily to and from very high voltages to permit low losses over large distances. Synchronous Generators Alternating current generators , c. Through a series of discoveries, the dynamo was succeeded by many later inventions, especially the AC , which was capable of generating. It is commonly known to be the Synchronous Generators SGs. The synchronous machines are directly connected to the grid and need to be properly synchronized during startup. Moreover, they are excited with special control to enhance the stability of the power system. Alternating current generating systems were known in simple forms from 's original discovery of the. Faraday himself built an early alternator. Large two-phase alternating current generators were built by a British electrician, , in 1882. His early alternators produced frequencies between 100 and 300. Ferranti went on to design the for the London Electric Supply Corporation in 1887 using an alternating current system. This basic system remains in use today around the world. A small early 1900s 75 direct-driven power station AC alternator, with a separate belt-driven exciter generator. After 1891, alternators were introduced to supply currents of multiple differing phases. Later alternators were designed for varying alternating-current frequencies between sixteen and about one hundred hertz, for use with arc lighting, incandescent lighting and electric motors. Self-excitation Main article: As the requirements for larger scale power generation increased, a new limitation rose: the magnetic fields available from permanent magnets. Diverting a small amount of the power generated by the generator to an electromagnetic allowed the generator to produce substantially more power. This concept was dubbed. The field coils are connected in series or parallel with the armature winding. When the generator first starts to turn, the small amount of present in the iron core provides a magnetic field to get it started, generating a small current in the armature. This flows through the field coils, creating a larger magnetic field which generates a larger armature current. Very large power station generators often utilize a separate smaller generator to excite the field coils of the larger. In the event of a severe widespread where of power stations has occurred, the stations may need to perform a to excite the fields of their largest generators, in order to restore customer power service. Main article: A homopolar generator is a comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim or ends of the cylinder , the depending on the direction of rotation and the orientation of the field. It is also known as a unipolar generator, acyclic generator, disk dynamo, or Faraday disc. The voltage is typically low, on the order of a few volts in the case of small demonstration models, but large research generators can produce hundreds of volts, and some systems have multiple generators in series to produce an even larger voltage. They are unusual in that they can produce tremendous electric current, some more than a million , because the homopolar generator can be made to have very low internal resistance. MHD generator Main article: A magnetohydrodynamic generator directly extracts electric power from moving hot gases through a magnetic field, without the use of rotating electromagnetic machinery. MHD generators were originally developed because the output of a plasma MHD generator is a flame, well able to heat the boilers of a. The first practical design was the AVCO Mk. In the from 1972 until the late 1980s, the MHD plant U 25 was in regular commercial operation on the Moscow power system with a rating of 25 MW, the largest MHD plant rating in the world at that time. MHD generators operated as a are currently 2007 less efficient than. Alternating current AC Induction generator Main article: may be used as generators, turning mechanical energy into electric current. Induction generators operate by mechanically turning their rotor faster than the synchronous speed, giving negative slip. A regular AC asynchronous motor usually can be used as a generator, without any internal modifications. Induction generators are useful in applications such as minihydro power plants, wind turbines, or in reducing high-pressure gas streams to lower pressure, because they can recover energy with relatively simple controls. They do not require an exciter circuit because the rotating magnetic field is provided by induction from the stator circuit. They also do not require speed governor equipment as they inherently operate at the connected grid frequency. To operate, an induction generator must be excited with a leading voltage; this is usually done by connection to an electrical grid, or sometimes they are self-excited by using phase correcting capacitors. Linear electric generator Main article: In the simplest form of linear electric generator, a sliding moves back and forth through a - a spool of copper wire. An is induced in the loops of wire by each time the magnet slides through. This type of generator is used in the. Larger linear electricity generators are used in schemes. Variable speed constant frequency generators Many efforts attempt to harvest natural sources of mechanical energy wind, tides, etc. Because these sources fluctuate in power applied, standard generators using permanent magnets and fixed windings would deliver unregulated voltage and frequency. The overhead of regulation whether before the generator via gear reduction or after generation by electrical means is high in proportion to the naturally-derived energy available. New generator designs such as the , the , or the are seeing success in variable speed constant frequency applications, such as or other. These systems thus offer cost, reliability and efficiency benefits in certain use cases. Main article: Motor vehicles require electrical energy to power their instrumentation, keep the engine itself operating, and recharge their batteries. Until about the 1960s motor vehicles tended to use with electromechanical regulators. Following the historical trend above and for many of the same reasons, these have now been replaced by with built-in circuits. Bicycles Bicycles require energy to power running lights and other equipment. There are two common kinds of generator in use on bicycles: which engage the bicycle's tire on an as-needed basis, and which are directly attached to the bicycle's drive train. The name is conventional as these they are small permanent-magnet alternators, not self-excited DC machines as are. Some are capable of , where the drive motor is used as a generator to recover some energy during braking. Sailboats Sailing boats may use a water- or wind-powered generator to trickle-charge the batteries. A small , or is connected to a low-power generator to supply currents at typical wind or cruising speeds. Genset Main article: An engine-generator is the combination of an electrical generator and an mounted together to form a single piece of self-contained equipment. The engines used are usually piston engines, but gas turbines can also be used. And there are even hybrid diesel-gas units, called dual-fuel units. Many different versions of engine-generators are available - ranging from very small portable powered sets to large turbine installations. The primary advantage of engine-generators is the ability to independently supply electricity, allowing the units to serve as backup power solutions. Human powered electrical generators Protesters at using bicycles connected to a motor and one-way diode to charge batteries for their electronics Human powered direct current generators are commercially available, and have been the project of some enthusiasts. Typically operated by means of pedal power, a converted bicycle trainer, or a foot pump, such generators can be practically used to charge batteries, and in some cases are designed with an integral inverter. At the end of which an undetermined period of rest and recovery will be required. The net electrical power that can be produced will be less, due to the efficiency of the generator. Portable radio receivers with a crank are made to reduce battery purchase requirements, see. During the mid 20th century, pedal powered radios were used throughout the , to provide schooling , medical and other needs in remote stations and towns. Mechanical measurement Designed to measure shaft speed, a tachogenerator is a device which produces an output voltage proportional to that speed. Tachogenerators are frequently used to power to measure the speeds of electric motors, engines, and the equipment they power. With precise construction and design, generators can be built to produce very precise voltages for certain ranges of shaft speeds. The generator is represented by an consisting of an ideal and an internal resistance. This is the simplest model of a generator, further elements may need to be added for an accurate representation. In particular, inductance can be added to allow for the machine's windings and magnetic leakage flux, but a full representation can become much more complex than this.
