aeroMaster for onshore applications

Our reliable and flexible onshore turbine platform can be adapted to all market requirements and local series production.

Cooling system
A smart patented combination of nacelle ventilation and component cooling with special cold / hot climate and sandstorm protection features for effective turbine operation under various environmental conditions
Rotor bearing unit
Zero-play double rotor bearing system for increased gearbox and bearing reliability
Yaw system
Proven technology with slewing ring, hydraulic calliper brakes and electrically driven planetary gearbox drives
Pitch system
State-of-the-art electric pitch system with modern drive and emergency power supply technology
Hydraulic torque support
Elastomer bearing with hydraulic features reduces constraint forces on gearbox and main bearings
Generator system
Highest flexibility with alternative generator systems (DFIG or PMSG) to adapt and optimize the turbine to local grid requirements
Internal service crane
Simple and cost-effective system consisting of curved profiles with monorail trolley chain hoist offers in combination with our spacious nacelle cover and even platform design excellent conditions for maintenance and repair jobs

The aeroMaster onshore turbines are available in different versions, comprising rated powers of 1.5, 2.0, 2.5, 3 and 4 MW with different rotor diameters as well as towers with multiple hub heights for an optimum energy yield at every site. Different climate versions of the aeroMaster for normal, hot and cold climates in combination with our smart sandstorm protection features ensure reliable operation in all climate zones worldwide. Together with the two alternative generator systems (DFIG, PMSG) available, the turbine can be adapted to all market requirements.

The aeroMaster drive train utilises a zero-play double rotor shaft bearing arrangement of one double-row tapered roller bearing and one cylindrical roller bearing in one single bearing housing. Together with a hydraulic gearbox support this bearing arrangement protects the gearbox from high loads, thus increasing the reliability of the gearbox and other drive train components.

The aeroMaster license offers customers a technology which can be adapted to all market requirements and operated under diverse environmental conditions worldwide. A fully developed supply chain with multiple sourcing for each component is available for all aeroMaster turbines. For details on license conditions, please contact our head office in Rendsburg.
