The Switch now offers widest range of permanent magnet packages available for wind power
(Thomson Reuters ONE) - By adding several new models to its offering, The Switch, aFinnish-based technology company, is the first company to provide acomplete portfolio of permanent magnet based generator packagesspecifically designed for maximized wind power generation. The latestadditions include an outer rotor generator, a modern-style 2.5 MWdrive train, and a double-fed option.VANTAA, FINLAND - July 6, 2009 - The Switch, a provider ofmegawatt-class permanent magnet generator and full-power converterpackages for wind power and other new energy applications, now offersthe most complete range of PM packages.Outer rotor generator - launch of a new platform for easy turbineintegrationThe introduction of the newest generator model combines the benefitsof a permanent magnet (PM) and direct-drive solution with an outerrotor. These PM machines represent the technology of choice fornext-generation wind power generators, as they offer a platform ofhighly integrated components that are built to last and require verylittle maintenance.The simple, straightforward design integrates the main shaft, mainbearings, gearbox and mechanical brake into a single generator"combo". The outer rotor reduces the weight of a direct-driveapplication. The generator shares a common bearing with the turbineitself, and the turbine's brake system has been integrated as part ofthe generator. The gain is realized in simplicity, fewer components -and therefore, higher reliability."For newcomers to modern technology in the wind power industry, TheSwitch outer rotor generator offers an ideal solution, because it'sthe fast-track way to make a high-performance turbine," saysJukka-Pekka Mäkinen, President and CEO of The Switch. "Our new outerrotor permanent magnet technology enables the best possible energyyield in varying wind conditions, thereby maximizing annual energyproduction.""As the industry shifts toward PM technology, The Switch is alreadyable to offer second generation products," Mäkinen continues. "Ourlarge direct-driven machines have been successfully operating since2005, a relatively long time in modern wind power history."The Switch outer rotor prototypes are currently being shipped toChinese Dongfang Electrical Machinery Co., Ltd. (DFEM), a leadingsupplier of cutting-edge wind power technology in the Chinese market.The generator's cast-iron body facilitates high volume production.The first orders of the outer rotor generator will be installed inthe mountainous region of Mongolia where they will operate in extremeconditions and at very low temperatures.2.5 MW redesign - more energy from existing turbineAnother new offering is the redesigned 2.5 MW drive train forconventional turbines. This PM generator and full-power converterpackage has been planned for manufacturers who aim to upgrade theirexisting wind turbine offerings without making substantial changes totheir proven designs."This modern-style 2.5 MW drive train is based on a growing marketneed to take greater advantage of existing turbine technology, butallowing it to do more with the wind available. In other words, tomaximize the amount of power to energy - which fits perfectly withour business mission," Mäkinen explains.Double-fed option with modular power packagesAs many wind power turbine manufacturers have selected double-fedinduction generator (DFIG) technology, originally due to lower costsand preference, The Switch now offers 1.5 MW and 2 MW packagesspecifically designed for these manufactures to help them tap intohigher power ratings. The Switch double-fed option comes with modularpower conversion packages and well-matched generators for exceptionalflexibility."The Switch is now well-known for its pioneering efforts to establishpermanent magnet solutions as the preferred choice in the industry,"says Reijo Takala, Vice President, Wind Power. "Yet, we've realizedthat turbine manufactures that apply double-fed technology, too, aresearching for ways to improve output performance and take greateradvantage of conditions with limited wind speed variations. TheSwitch now can serve these manufacturers with flexible converter andgenerator solutions and high component reliability. We have been ableto bring our know-how in world-class wind solutions to deliversuccessfully to those who want to stay with the double-fed approach."About the SwitchThe Switch provides unique power conversion systems - powerconverters, machines and other electrical equipment needed fordistributed power generation and industrial processes. Customers usethe innovative products and systems of The Switch as part of theirown machines or systems in wind turbines and other renewable energyapplications. The Switch solutions support the battle against climatechange and help to preserve energy resources. www.theswitch.comFor further information, please contact:Sabine DomsMarketing CoordinatorThe SwitchMobile: +358 40 808 0586Email: sabine.doms(at)theswitch.comhttp://hugin.info/138845/R/1327152/312584.jpgThis announcement was originally distributed by Hugin.
