Reliable brake solutions for wind turbines – now and in the future.
What is the main function of a flange failsafe brake in a wind energy converter?
The main function of a flange failsafe brake is to safely stop and hold the rotor of a wind turbine in an emergency or during maintenance safely stop and hold. It prevents critical damage, for example, from over-rotation in the event of a grid failure, and is thus essential for plant protection and reliability.
How does the failsafe principle work in these brakes?
The failsafe principle usually utilizes pre-tensioned spring packages. In normal operation, the brake is actively released (e.g., electromagnetically, hydraulically, or pneumatically). In case of a power failure or fault detection, the releasing force is removed, and the springs generate automatically the full braking force, to safely hold the rotor, even in the event of a control failure.
Why are robust construction and high-quality materials so important for flange failsafe brakes?
Wind turbines are exposed to extreme environmental conditions. Robust constructions und high-quality, corrosion-resistant materials (e.g., certified spring steels, special coatings) ensure the longevity and reliability of the flange failsafe brake even at temperatures from -40°C to +70°C and protect against premature wear.
What role does effective thermal management play for brake performance?
Substantial heat is generated during braking. An effective thermal management through optimized design (e.g., cooling fins, ventilation channels) is crucial to prevent overheating, brake fading, and premature wear of the brake pads. This can increase the service life of the pads by up to 30% and ensure consistent braking performance.
What are the key selection criteria for a flange failsafe brake for wind energy converters?
The most important criteria are the sufficient braking torque for maximum load, a short response time (often <200 ms) for emergencies, the appropriate IP protection class (e.g., IP55/IP66) against environmental influences, as well as long service life and low maintenance.. ATEK Drive Solutions supports the precise design of these parameters.
Why is the integration of the brake with pitch and yaw systems advantageous?
An intelligent integration of the flange failsafe brake with pitch and yaw systems enables combined braking strategies. For instance, an aerodynamic braking can first be achieved through blade adjustment, followed by a smoother mechanical brake application. This synergy can reduce wear and loads on the drive train by up to 15%..
What future developments are there in flange failsafe brakes?
Future trends include smarter brakes with integrated sensors for condition monitoring and predictive maintenance, lightweight construction to reduce the weight of the nacelle and quieter designs. These developments aim to lower operating costs and increase the acceptance of wind turbines..

Fundamental role of Flange failsafe brakes in wind energy converters recognizing
Reliability of wind turbines under extreme conditions is vital. Flange failsafe brakes increase the safety and efficiency of wind energy converters. ATEK offers proven solutions for such brake systems; details upon request.
The core function: Essential safety elements
Flange failsafe brakes are critical during system failures. These safety brakes for wind turbines stop and hold the rotor in emergencies or during maintenance, preventing, for example, over-rotation in the event of a grid failure and significant damage. Redundancy is fundamental for plant protection. ATEK focuses on the reliability of these essential components. Learn more about safety brakes. Trends in the renewable energy sector.
The failsafe principle: Automatic activation in emergencies
The failsafe principle, which applies to a flange failsafe brake for wind energy converters , usually utilizes spring pressure: Normal operation keeps the brake energy-released. In case of a power failure or fault detection, pre-tensioned springs automatically generate full braking force, even in the event of control failure. A response time of under 100 ms minimizes damage.Optimal braking performance for Flange failsafe brakes ensured through intelligent design and material selection
Choosing robust construction and high-quality materials
Wind turbines require robust materials, especially for safety-critical components like the flange failsafe brake. ATEK Flange failsafe brakes uses corrosion-resistant materials and special coatings; seals/housings withstand -40°C to +70°C. The quality and fatigue resistance of the spring packages determine the lifespan of these brakes for wind energy converters. ATEK uses certified spring steels. High torque safety brakes for pitch systems.
