3.6M140 EBC

A Power Boost for the Leading Model

The predecessor of this model, the 3.4M140 Eco Blade Control (EBC), already offered a yield more than 20 percent higher than other turbines in the 3 MW class. The latest increase in nominal power to 3,600 kilowatts enables a further 3 percent potential increase in yield. Moreover, the turbine is suitable for locations assigned wind class IEC IIIA and IECS based on IEC IIB. The new hub height of 160 meters has a higher energy yield to match and enables efficient operation even in locations with low winds.

  • Nominal power: 3,600 kW
  • Rotor diameter: 140 m
  • Hub height: 107 - 163 m


  • Wind class: Low to Medium Wind
  • Operating temperature range: -20 – +35 °C
  • Rotor surface: 15,394 m²

Senvion Technology

The 3.XM series features a well-proven modular and evolutionary technology concept. The smart and robust design results in a highly efficient and reliable turbine concept: from the aerodynamically optimized rotor blade, compact and efficient drivetrain, advanced control technology right through to the transformer. This flawless interplay delivers high energy yields while keeping sound emissions low.

The EBC platform - Dependable, durable and suitable for higher wind classes

The Eco Blade Control generation of turbines boasts high yields at low-wind locations, an outstanding operational lifespan of 25 years, and a low sound power level. Light weight construction of the blade due to our Rodpack Technology and an advanced load management technology completes the benefits of this turbines.

  1. 1

    Generator/frequency converter

    • Variable speed range for optimum yields
    • Fully encapsulated generator with air-air heat exchanger
    • Optimum temperature inside generator, even at high ambient temperatures
    • Water-cooled converter power electronics for optimised cooling
    • The converter and controllers are located in the tower base, leaving even more space in the nacelle and making operation that much easier

  2. 2

    Gear system

    • Planetary/spur gear
    • Satisfies stringent demands in terms of service life and operating smoothness in line with Senvion gear specifications
    • Elastomeric torque arm bearing for structure-borne sound insulation
    • Low temperature thanks to efficient oil cooling system
    • Three-stage oil filter system for excellent oil quality

  3. 3

    Rotor blade

    • Individual blade profiles for optimal aerodynamics of the rotor
    • Robust aerodynamic design guarantees best possible performance, even in difficult wind conditions or when dirty
    • Proven quality, tested statically and dynamically in accordance with IEC specifications
    • Fully integrated lightning protection in accordance with IEC protection class I

  4. 4

    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

  5. 5

    Rotor bearing and rotor shaft

    • High quality spherical roller bearing with bearing with perfectly fitted bearing housing and permanent lubrication for maximum service life
    • Rotor shaft aligned with transfer of torque

  6. 6

    Azimuth

    • 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

  7. 7

    Holding brake

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

  8. 8

    Tower

    • 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
