In mid-2008 the company began testing of development prototypes of direct drive wind turbines; units based on the geared SWT-3.6–107 were installed in 2008 with a permanent magnet generator directly replacing the gearbox and alternator; [32] [note 2] Successful tests led to development of a new production design by 2009.

Enercon wind turbines have some special technical features compared to turbines of most other manufacturers. One is the gearless propulsion concept, which Enercon pioneered since 1993. The first generation of gearless turbines was the E-40/500 kW series.
Wilmington, Delaware, Oct. 17, 2024 (GLOBE NEWSWIRE) -- Allied Market Research published a report, titled, "Direct Drive Wind Turbine Market by Capacity (Less than 1MW, 1MW to 3MW and More than 3MW), Technology (Permanent Magnet Synchronous Generator (PMSG), Electrically Excited Synchronous Generator (EESG)), Installation (Offshore and Onshore), and End Use (Industrial, Commercial, Residential ...
This list also includes the most powerful onshore wind turbines, although they are relatively small compared to the largest offshore ones. As of June 2024, the most powerful wind turbine in operation is the world's first 18MW semi-direct drive offshore wind turbine, developed by Dongfang Electric Corporation. [1] In October 2024, Dongfang ...
Systems that use magnetic direct drive turbines require greater amounts of rare-earth metals. Therefore, an increase in wind turbine manufacture would increase the demand for these resources. By 2035, the demand for Nd is estimated to increase by 4,000 to 18,000 tons and for Dy by 200 to 1,200 tons.
