Direct drive technology

EWT's gearless wind turbines
In EWT wind turbines, the rotor directly drives the synchronous generator, without the use of a gearbox. This is important because various independent studies have concluded that malfunctioning of gearboxes is the main cause of downtime. Also the absence of a gearbox reduces noise levels, and the noise of the generator is minimised by lowering the generator rotation speed by a factor of more than 100 versus a typical gearbox-type wind turbine.
