REpower 6M Offshore Wind Power(8)

Pitch system:

Electrical system, which is virtually maintenance-free High-quality, generously dimensioned blade bearings with a closed system for permanent lubrication High reliability due to redundant blade angle detection with two independent measurement systems High safety due to independent control and regulation systems for each rotor blade Permanent charge and status monitoring of the battery boxes

Azimuth / yaw system:

Externally geared four-point bearing, driven via generously dimensioned, high-quality gear motors Hydraulic holding brakes with hydraulic pressure reservoir (they relieve the drives when idle and stabilize the nacelle) Minimum loading of the drives due to the low friction of the four-point

bearing

Rotor hub:

Power-flow-optimized design Optimal integration of the pitch drives Generously dimensioned spinner for reliable access to the hub regardless of the weather

Rotor bearing and rotor shaft:

Double-mounted distributed drive train CARB bearing and high-quality fixed spherical roller bearing with optimally adjusted bearing housing Automatic permanent lubrication of the bearings for maximum service life

Lightning protection:

Rotor shaft cast in a power-flow-optimized manner
