Nacelle / Rotor design

EWT wind turbines have very compact nacelle designs, because of the absence of a gearbox. In competitor wind turbines nacelles typically have a long, rectangular shape, whereas an EWT nacelle is essentially an extension of the tower to which the generator and the rotor are mounted. 

More efficient and serviceable design

A key advantage of this nacelle lay-out is a lower top-head-mass and easy access to nacelle and hub. Another key feature of the nacelle design is its single bearing concept. By applying just one main bearing, the number of components in the wind turbine is lower, which results in a more efficient but also more serviceable design.   

Spacious nacelle design

For excellent serviceability and maximum safety, service and maintenance activities can be carried out at a lower cost and risk in EWT turbines, because there are no shafts in the nacelle and the rotor hub can be reached from the inside. 

Rotor blades

Large rotor diameter to achieve high energy yield. Optimum aerodynamic performance, reducing noise emissions.
