Wind energy

We make the production of clean energy safe and efficient

mayr ^® power transmission bundles its know-how and decades of experience in the offshore sector in safety brakes for pitch and azimuth drives. The safety brakes for wind power plants represent maximum fail-safe function, minimum downtimes and constructional design diversity, and reduce the operating costs.

Developments in wind power are continuing apace. This also poses new challenges for braking systems. For this reason, mayr^® power transmission has developed an application-optimized version of the proven ROBA-stop^®-M brake series specifically for pitch servomotors and controlled AC drives. The brakes offer high performance density and are suitable for applications with ambient temperatures up to +90 °C and mounting flange temperatures up to max. +120 °C. 

The portfolio of safety couplings is also extensive. It ranges from overload systems for gearboxes in wind turbines to torque limiters for the drives of climbing aids in the towers and switchable couplings for the drives of maintenance and installation platforms to powerful large torque limiters for gear test benches such as the EAS^® HT.

Check this before you select a Wind Power Brake:

Safe and reliable brakes control the trouble-free operation of wind turbines, whereas unreliable brakes in pitch and yaw systems can cause serious safety hazards. Not all brakes on the market are safe and reliable to use in those applications. You cannot delegate responsibility, so get involved and check carefully before you purchase a brake for the pitch and yaw system of a wind turbine.

1. Which market position does the brake supplier have in the wind power industry and how many years experience does the supplier have?
2. Take the time to visit the factory of the supplier. Seeing is believing. Does the supplier have state of the art quality processes, adequate qualification testing equipment?
3. How is the brake torque specified? Is there test equipment available for static and dynamic brake torque?
4. Does the supplier have climate chambers for brake testing at -40 °C up to + 60 °C and different levels of humidity?
5. Does the brake supplier have a certificate, i.e. GL, confirming the compliance with the CCV low temperature requirements down to -40 °C?
6. Can the supplier offer full traceability and provide serial numbers for each unit?
7. Does the supplier have 100 % end line testing with automatic storage of all measured data?
8. Is a high voltage test with min. 4000 V peek carried out for every brake to avoid unexpected coil damage in the field?
9. In case of release monitoring: Is the switch already mounted, adjusted and tested by the brake manufacturer prior to delivery?
10. Does the supplier have a world-wide network for support?
