Wind turbines from Germany
Amperax Energie GmbH is a German manufacturer of wind turbines headquartered in Itzehoe, Schleswig-Holstein. The company develops and manufactures the 3-MW A3000 turbine with gearless direct drive, which is designed for low-wind inland sites. The turbine uses a direct-driven permanent magnet synchronous generator (The Switch, type PMM3000A00) with full converter technology, whose power electronics are housed entirely in the tower base. Complete in-house assembly takes place in modern production halls in Germany; components such as the generator, converter, rotor blades and control system come from experienced suppliers such as The Switch, Euros and Bachmann electronic. With a rotor diameter of 116 m, the A3000 is available for hub heights of 92 m (steel tube tower), 122 m (hybrid tower for cold temperatures down to -30 °C) and 142 m (hybrid tower with concrete base) and is certified according to IEC III/DIBt Wind Zone 2. In addition to turbine sales, Amperax offers technical operational management, service and maintenance with 24/7 remote monitoring via SCADA. The first prototype of the A3000 with 142 m hybrid tower has been in operation at the Krackow-Glasow site in Mecklenburg-Vorpommern since December 2013.
