The following is google translate transcript of the de.wikipedia.org/wiki/enercon page:

The Enercon GmbH is the largest the German manufacturer of wind energy plant n (WEA) with master seat in Aurich (East Frisia). The 1984 of the today's owner Aloys Wobben created enterprises busily world-wide over 8.000 coworkers and had 2004 a conversion of 1.2 billion euro. The enterprise possesses over 40% of the patents within the range of the wind energy technology world-wide. A further characteristic at Enercon is the fact that the enterprise among the sieved prominent WEA manufacturers (has the one market share of over 90%, cumulated) represents the only not quoted finance company. The world market portion of Enercon amounted to in the year 2004 15.8%, thus is to Enercon because of third place behind Vestas with 34,1% and Gamesa with 18,1%. Managing directors are Aloys Wobben and Hans Dieter chaining TIG. Manufacturing plants of Enercon stand for Malmö/Sweden in Aurich/Lower Saxony, Emden/Lower Saxony, Magdeburg/Saxonia-Anhalt, Turkey, Brazil, India and. Enercon is before Vestas and Siemens of the wind energy equipment manufacturers with the world-wide highest manufacturing depth. Generators, cars, concrete and steel tube towers, rotor blades, controls and power electronics are only manufactured meanwhile in own factories of the enterprise. Enercon Windenergieanlagen with year of construction after 1993 draw by a transmissionless plant concept out (until 1993 with transmission impulse seaweed). Rotorblätter are connected by the hub directly with the runner of a ring generator. Together these construction units rotate over a front and a rear main warehouse around a standing axle pivot. So can be done to trouble-prone and maintenance-intensive (e.g. regular oil changes) mechanical transmissions s without the employment. This is reached by a special design generator of the s. Since the generator with the same number of revolutions runs as the rotor, also the number of mechanical load changes is over the life span clearly smaller. The rotor speed amounts to depending upon installation type and wind conditions approximately 8 to 60 rpm, while with a transmission plant a generator number of revolutions is reached by approximately 1500 rpm. The Enercon plants can be differentiated optically easily by the plants of other manufacturers. The machine cars of the plants are usually drop-shaped. In Germany and many other countries the tower over the foundation carries coloured gradated green rings, which become ever brighter from bottom to top. On islands the manufacturer offers alternatively a gradation in blue, as converted on the island Borkum. The NCS (Natural Color Scheme) gradation is to let the plant towers fade in better into the horizon. The Design of this remarkable car was developed by the British architect Sir Norman Foster, which sketched among other things also the dome citizens of Berlin of the realm daily. The rotor blades order as only on the market over blade tips similarly Winglet the s with airplanes. thumb|Enercon E-40 (car Design until 2001) ==Anlagentypen== ===E-12=== *5 plants established *Nennleistung 30 kW *getriebelos *wurde between 1997 and 2000 produced ===E-15/E-16=== thumb|E-16 in largely giving mountain/Schleswig-Holstein *46 plants established *Nennleistung 55 KW *Triebstang with transmission and induction generator (transmission plant) *wurde between 1985 and 1989 produced ===E-17/E-18=== thumb|E-17 at the company headquarters in Aurich *158 plants established *Nennleistung 80 KW *Triebstrang with transmission and induction generator (transmission plant) *wurde between 1989 and in the middle of the 90 ' it years produced ===E-20=== *Errichtung prototypes in the autumn the 2006 in Aurich in the local part barrier *Nennleistung 100 KW * Stall - plant with steel rotor blades *der generator supplies to 400 V with *die entire plant fits to an overseas container *bei the three-part steel tube tower of 20, 30 or 40 m length can for transport the top into the lowest tower part be pushed in (space saving in the container) ===E-32/E-33=== thumb|Enercon E-32, Fehmarn *186 plants established *Triebstrang with transmission and induction generator (transmission plant) *Nennleistung 300 KW *Hydraulische blade control *wurde between 1988 and 1993 produced ===E-30=== thumb|Enercon E-30 Aurich *575 plants were established to 2,5m/s since 1994 established (conditions in the middle of 2005) *Nennleistung 300 KW (older plants 230 KW) of more *Rotordurchmesser 30 m *Nabenhöhe to 50 m *Einschaltwindgeschwindigkeit *Abschaltwindgeschwindigkeit 28-34m/s *Umstellung production on E-33 with new rotor blade profile in the year 2005 ===E-33=== *produziert since 2004, 5 plants (to in the middle of 2005) *Nachfolgemodell the E-30 with new rotor blade Design *getriebelose plant *Nennleistung 330 KW (25% yield increase to the E30) of *Rotordurchmesser 33.4 m *Stahlturm 49 m ===E-40=== thumb|Enercon E-40, southearthcalibrate *Prototyp 1992 established *meistgebaute modern wind energy plant of the world more *über 4,135 plants since 1993 established (conditions August 2005) *getriebelose plant *offizielle type designations ** E-40/5.40 rotor diameter 40 m, rated output 500 KW ** E-40/6.44 rotor diameter 44 m, rated output 600 KW *Die production 2004/2005 to the successor E-48 one changed over.

The energy yield of the E-70 could be increased by a new and so far only rotor blade organization converted by Enercon with nearly same rotor diameter around 10% to 15% (location-dependently). Also the inside is used/hubnear rotor blade range for lift production. ===E-70=== thumb|Montage of a E-70 *Nachfolgemodell the E-66, introduction 2004 *ca. 140 plants produces and developed (conditions April 2005) *getriebelose plant *Nennleistung: 2 MW (since autumn 2006 also 2.3 MW) *Rotordurchmesser: approx. 71 m *Nabenhöhen: 58, 64, 85, 98 and 113 m depending upon tower variant *Drehzahl: 6 - 21.5 rpm *Blattspitzengeschwindigkeit: 22 - 80 m/s *Einschaltgeschwindigkeit: 2.5 m/s *Nennwindgeschwindigkeit: 12.5 m/s with 2MW (13.5 m/s with 2,3 MW) *Abschaltgeschwindigkeit: 28-34 m/s ===E-82=== *Nachfolgemodell the E-66, inland countries version of the E-70 with increased rotor diameter *Prototypen: December 2005 in Simonswolde, municipality Ihlow, East Frisia; second plant at the beginning of of 2006, stone head island, Magdeburg Rothensee *Markteinführung center 2006 *getriebelose plant *Nennleistung: 2 MW, higher rated output in preparation more *Rotordurchmesser: approx. 82 m *Nabenhöhen: 70 m, 78 m, 85m, 98 m, 108 m and in the future 138 m *Drehzahl: variable, 6 - 19.5 rpm *Blattspitzengeschwindigkeit: 25 - 80 m/s *Einschaltgeschwindigkeit: 2.5 m/s *Nennwindgeschwindigkeit: 12 m/s *Abschaltgeschwindigkeit: 22 - 28 m/s ===E-112=== the E-112 is with a rated output of 6 MW the highest performance wind energy plant of the world. Into Magdeburg produced plant a rotor diameter of 114 m (the first plant 112 m and initially 4.5 MW) and a hub height of 125 m has (can vary depending upon tower and foundation execution). The height to over the rotor circle amounts to scarcely 180 M. of the diameters of the car amounts to approx. 12 m, whereby a weight of over 550 t (with rotor blades) on that weighing concrete tower is appropriate for approx. 2,500 t. The directpropelled (transmissionless) external runner synchronous generator contributes with approximately 450 t to the car weight. The diameter of the concrete tower underneath the car amounts to approx. 4 m, at the basis of the tower about 12 M. the rotor blades for the first two plants (Egeln and Wilhelmshaven) with Abeking & Rasmussen in Lemwerder was manufactured. The quantity production of the E-112-Rotorblätter took place then from at the end of on of 2003 in a Enercon Rotorblattfertigung in Magdeburg Rothensee. From there out the rotor blades with inland waterway crafts are delivered over Elbe or central land channel. A rotor blade is about 52 m long and weighs approximately 22 t. The small number of revolutions of the large plant works less disturbing than the fast numbers of revolutions of smaller plants. It replaced in the energy yield three to four plants of the type E-66 and is thereby more quietly than three E-66 together. The future of these large plants is to be appropriate for the time being ashore, later however also in offshore ones - for range. thumb|E-112 in Egeln thumb|Enercon Windenergieanlage E-112 at the Ems in Emden, one the first “Near shore Windenergieanlagen so mentioned” in Germany *Anzahl the established plants (conditions September 2006): 9 *Nr.1 2002 Egeln with Magdeburg *Nr.2 2003 Jadewindpark, Hooksiel with Wilhelmshaven *Nr.3 2004 Larrelter Polder, Emden *Nr.4 2004 Ems delta with Emden *Nr.5 2004 Larrelter Polder, Emden *Nr.6 2005 Larrelter Polder, Emden *Nr.7 2005 Larrelter Polder, Emden *Nr.8 2005 DEWI OCC test field, Cuxhaven *Nr.9 2006 wind park Druiberg, district half No. 1 in Egeln. First Prototyp this plant was established in August 2002 in close proximity to Magdeburg with Egeln. The tower was established locally in sliding form stechnik. With metal ropes (braids) afterwards the reinforced concrete is brought hydraulically on tension. Generator and electrical equipment came from the Magdeburger manufacturing plants. No. 2 north of Wilhelmshaven, i.d.Nähe of Hooksiel. No. 3 in Emden. The third plant belongs to the regional power supplier EWE and stands in Emden in the proximity of the Volkswagenwerk directly behind the dyke. There also the fifth plant in approximately 300 m became distance. Starting from the third plant the rotor diameter of the E-112 was extended as consequence of changes within the hub range on approx. 114 m. No. 4 in Emden, plant No. 4 was planned by the company Enova and established October 2004 in the water before the dyke in direct proximity to the Emder port. Operator is likewise EWE AG from Oldenburg. Also logistics for the structure took place from the water side around experiences for offshore projects to collect. The quantity of electro-technology is new in the tower of the plant in the water. In photos by the structure a “elastic module steel cabinet house” mentioned “” is to be recognized, which is enough over approx. four floors. A E-112 wins approx. 16 million kilowatt-hours/year at this location Emden (108 m hub height). With corresponds to the current consumption of approximately 4,570 households with a need of 3,500 KW/H/year each or of 16.000 persons (1,000 KW/H/year). No. 5 to No. 7 the fifth plant was established for public utilities Emden end of 2004, the distance to No. 3 amounts to approx. 300 M. the plants No. 6 and 7 in November/December 2005 near the Emder Volkswagen work was likewise established (operators: Public utilities Emden), so that now a first wind park with 5 E-112 is there. These two plants are the first official wind energy plants with 6 MW rated output, which a world record is. The hub height amounts to 124 m, prestressed concrete tower. 17 millions are expected kWh/a. No. 8 in Cuxhaven. Plant No. 8, with 6 MW rated output, was likewise established in December 2005 with Cuxhaven on the DEWI OCC test field. The steel tower (manufactured in Malmö, Sweden), stands on a concrete socle of 15 m height, hub height altogether 116 m, in foundation and base puts 1200 m ³ concrete and 130 tons reinforcing steel. 15 millions are expected kWh/a. Operator is the power supplier EWE, Oldenburg. No. 9 became in September 2006 with Dardesheim (district half, Saxonia-Anhalt) in the wind park Druiberg establishes. The rotor diameter amounts to 114 m, the rated output 6 MW also here. However those originally sixth plant (now as respected in Cuxhaven one established) should be established according to plan center 2005 500 m far away from the bank north of Wilhelmshaven with Hooksiel in the water in the North Sea. It should be attainable different than the “Nearshore” E-112 in Emden (footbridge to the bank) only by ship. The special to these water standing plant deep into five meters should be the foundation. It concerned Saugeimer foundation (English “suction bucket”). A turned “steel bucket” is aspirated by negative pressure on the inside into the mud, until it is completely filled with mud. After end of the utilization period of the plant the foundation can be pressed then likewise “simply” by positive pressure the soil. Complex ramming and foundation works are void. Unfortunately when the assembling of this foundation at the end of of April 2005 deformations arose to “bucket” (buckets), so that the structure up to the cause clarifying was stopped and broken off later completely. (see www.enercon.de/pressemitteilungen). Further plants are to develop in Hamburg docklands with Altenwerder, with so far not a hub height of approximately 140 M. ===E-126===, reached by concrete towers, on Hanover fair the 2006 the successor of the E-112, the E-126 with larger rotor, for the new Enercon rotor blade profile, larger hub height and thereby improved yield and economy, for 2007 were announced. The production and the selling of the E-112-Anlagen are changed over therefore to the E-126. The hub height is to amount to 135 m on a finished unit concrete tower. ==Industriespionage with Enercon== in the years 1994/1995 were heard Enercon by the service National Security Agency of the USA by Echelon, to that the won data the US-American competitor “Kenetech wind power Inc.” to come left. This used the data, in order to provide entrance to Enercons core technologies and to patent these in the USA, which led to the fact that the US-American market Enercon is locked into the year 2010. == relationship to trade unions == Enercon is accused to prevent one trade union liche organization of its coworkers.

Location of Enercon

Before anyone makes a remark about Friesland being a region in the Netherlands *and* in Germany: fine, see Friesland_(district) for additional info:

This article is about the German district. For the Dutch province of the same name, see Friesland; for the German and Dutch name for the entire coastal region, see Frisia.

But the company really is based in Aurich, Germany, not in the Netherlands. Flex Flint 12:16, 23 February 2007 (UTC)

IP theft allegation

• Someone removed the IP theft charge, I've restored the references to that charge. It should probably read "aleged". Also, it left out the part in the reference citing an opposite charge (against) Enercon of patent infringement. The reason ECHELON provided information to Kenetech (according to the European Parliament website) was because Kenetech was pursuing legal action against Enercon for IP theft. So both companies are making charges at eachother, but only one side was presented in the section that got removed. Can someone with a better grasp of German than me read through these references and see if the removed section was neutral? --Duk 17:33, 30 April 2007 (UTC)

• The IP theft charge cited U.S. patent 5,083,039 as the infringement on Enercon's gearless wind turbines. But the patent isn't specifically for "gearless" wind turbines. I'm guessing the alleged infringement probably has to do with the electrical circuit controlling powerfactor and torque load on the generator. Again, maybe someone with good German skills can look this over and re-add a neutral section about the theft allegations. --Duk 17:43, 30 April 2007 (UTC)

Ah, here it is. The patent has 138 claims, and a US court ruling found that Enercon infringed on claim 131, which deals with [[power factor]

I don't have the time to translate these huge articles. I can only tell that the deleted parts were properly sourced with these articles. --Tilman 18:12, 30 April 2007 (UTC)

The question is whether the (currently deleted) section was neutral. There were claims of IP theft by both sides, but only one side was presented in our article. Our article presented the ECHELON connection as the method that Kenetect stole information, but according to the European Parliament website this event was Kenetect's attempt to prove the opposite, if I read it correctly. --Duk 18:22, 30 April 2007 (UTC)

If it wasn't neutral, then the correct solution would be to present the side of Kenetech. I don't read the European Parliament website the same way as you - to me, it seems also that Kenetech was spying on Enercon, and then registered the patent before the Germans. --Tilman 18:32, 30 April 2007 (UTC)

Kenetech seeking evidence for legal action against Enercon for breach of patent rights on the grounds that Enercon had obtained commercial secrets illegally, According to an NSA employee, detailed information concerning Enercon was passed on to Kenetech via ECHELON [1]

That doesn't say Kenetect stole secrets and patented them. It says Kenetect got the information from ECHELON in order to pursue legal action against Enercon for alleged theft. --Duk 18:22, 30 April 2007 (UTC)

Oh, I missed that one. Feel free to add it somehow, in the spirit of presenting both sides. I wonder what Kenetech's theory is how Enercon got their secrets. --Tilman 19:00, 30 April 2007 (UTC)

OK, I rewrote the section. But I still can't understand ref #2 very well (Die Zeit: 40/1999 "Verrat unter Freunden"). Perhaps you could read it over and revise my edit as needed, thanks. --Duk 19:10, 30 April 2007 (UTC)

The Zeit article is mostly about NSA and ECHELON. But it also describes how a Kenetech employee, with the help of a german (Ubbo De Witt), made some photographs on location. To do this, they had to enter a secret keycode into the machine. Later enercon learned that all this had been possible because the NSA had bugged their phones / data lines and delivered intellectual property to Kenetech. After this, enercon replaced all their communication lines with high security lines. --Tilman 20:05, 30 April 2007 (UTC)

The IP infringement ruling concerned variable speed generation of electricity. The issue is the use of IGBTs to take sub or super synchronous frequencies and use DC pulses to produce a synchronous 50/60hz sine wave to ensure more efficient grid-synchronous power production over variable generator RPM. The reason GE (and Gamesa under license) are able to use this technology and none other in the North American market is directly a result of Kenetech's theft and subsequent patenting of the technology. —Preceding unsigned comment added by 208.126.115.234 (talk) 09:24, 23 December 2009 (UTC)

Poo?

I noticed that it says "poo" above Enercons icon. to the top right. LOL i know the company isnt in fact.... poo. this is a false report and needs editing. —Preceding unsigned comment added by 24.129.161.182 (talk) 21:26, 23 September 2008 (UTC)
