Turns low wind speeds into revenues

The MM100 is ideally equipped to make efficient use of all locations with low wind speeds: a rotor diameter of 100 m, a swept rotor area of 7,854 m² and hub heights ranging from 75 to 100 metres. Moreover, its low sound power level of 103.8 dB(A) makes it one of the quietest systems in its class and therefore particularly interesting for onshore wind farms which are subject to noise restrictions.

    • Proven quality, tested statically and dynamically in accordance with IEC specifications
    • Fully integrated lightning protection in accordance with IEC protection class I

  4. 4

    Rotor hub

    • Dimensionally stable thanks to compact design and alignment with transfer of torque
    • Optimum integration of pitch drive systems
    • Generously proportioned spinner ensures safe access to hub in all weathers

  5. 5

    Pitch system

    • Virtually maintenance free electrical system
    • High-quality, large blade bearing with permanent track lubrication and external gearing
    • Integrated deflector in the spinner as protection from the elements
    • Maximum reliability through redundant blade angle detection with two independent measuring systems
    • Fail-safe design with independent drive and control systems for each rotor blade

  6. 6

    Rotor bearing and shaft

    • High quality spherical roller bearing with bearing with perfectly fitted bearing housing and permanent lubrication for maximum service life
    • Q&T steel rotor shaft cast in alignment with transfer of torque

  7. 7


    • Four-point contact bearing with external gearing, powered by top quality high-performance gear motors
    • Holding brakes with hydraulic pressure accumulator for fail-safe function relieve drive systems when inoperative and stabilise nacelle
    • Minimum stress on the drive trains thanks to low friction of four-point bearing and brake release during wind tracking

  8. 8

    Holding brake

    • Generously dimensioned disc brakes hold rotor safely
    • Soft brake function for minimum wear of gearbox

  9. 9

    Tubular steel towers

    • Natural frequency of tower higher than rotational speed of rotor (rigid design) ensures minimum stress on tower and nacelle
    • No speed restrictions, as no frequency interference
    • Maximum component safety thanks to L-shaped flange and stress-optimised door opening
