Sun & Wind Energy 8+9/2014 The next generation – the FWT 3000 wind turbine. Please visit us in Hamburg at WindEnergy Trade Fair from 23. to 26.September 2014 in Hamburg. Booth No. A1.236 www.windenergyhamburg.com The development of the new FWT 3000 generation of wind turbines encompasses over 20 years of experience in wind energy. Having been designed particularly for inland locations, the FWT 3000 boasts a compact drivetrain, a logistics-friendly hybrid tower and the high-performance HybridDrive, which incorporates the advantages of a gearless turbine into a system with a gearbox. 3 MW capacity | 120 m rotor diameter | 140 m hub height www.fwt-energy.com control, communication, and switching. It also encompasses energy distribution at low and medium voltage levels, pitch and yaw drives as well as generator systems for energy production. A range of power storage solutions, for example the Siestorage battery storage system, are also part of the Siemens portfolio. Hall B7, Booth 416 Manufacturers of wind turbines have a new transmission platform from Bosch Rexroth available for turbines with a rated power between 3 and 4.5 MW. With a compact transmission consisting of two in-line planetary and one downstream spur gear stage, the company is focusing on reducing the cost of energy (CoE) as well as increasing reliability using this transmission concept. Adaptations to customer-specific requirements are rapidly possible thanks to the modular concept, and the time to market is shortened. Rexroth has strongly standardised the parts, which means that they are also available more quickly. Structural changes are also intended to bring further benefits – for example the planetary gear takes over the function of the outer planetary bearing ring, which prevents bearing damage caused by a rotating conventional outer ring. An optimised tooth meshing sequence ensures that the transmission runs very smoothly and improves noise characteristics. Optimised tooth flank surface roughness reduces the risk of micro-pitting. Hall A1, Booth 432 At Bosch Rexroth, calculation methods for increasing reliability used by the automobile industry are incorporated in the development and production of the transmissions.
