Rotor brakes for wind turbines

By Paul Dvorak | January 13, 2010

Twiflex brakes are fully assembled, provide high levels of reliability, easy electronic monitoring and maintenance, and come with organic or metallic linings. Friction liners are sized to ensure adequate heat dissipation during an emergency stop and with an even pressure distribution across pad surfaces.

The brakes come in a range of braking forces from 100 N to 1 MN to meet the torque requirements of the most common turbines. Rotor-brake models include the GMR (15 to 35 kN), the VCS (20 to 60 kN), and the VKSD (50 to 119 kN). VCS and VKSD brakes are available as standard and floating models. Floating, single-sided brakes are mounted on sliding bushings to save space.

Twiflex spring-applied, hydraulically-released, caliper brakes are typically mounted to a turbine’s ma

Twiflex Model GMR-SH disc calipers generate a braking force of 35 kN. The line includes three models to generate braking forces of 15 to 119 kN.

in rotor shaft, between gearbox and generator, and used primarily as safety brakes during emergency stops under high wind conditions. All units are engineered to handle the large output torque generated by the high ratios found in wind-turbine gearboxes. The brake models are in operation today on hundreds of wind turbines around the world. Twiflex is a member of the Altra Industrial Motion family of power transmission companies.

    Dear MR./MRS.
    Hi. We are students in Yildiz Technical University, Mechanical Eng. Dept., in Turkey. We have been interested about Renewable Energy Systems Design. At the reason of this interest, we have just finished writing a introduction book about Wind Turbine Design, which includes your photos/informations, at the end of one end half year, thanks to God. And we also want to build up a new web site about renewable energy which includes our book so includes your documents indirectly. So we ask you if we get a permission from you/your company to use your documents in our web site, if it is possible.
    Please contact us as soon as possible.
    Sincerely.

    WTS is a small (5kw through 25 kW) wind turbine manufacturer. We are interested in emergency braking system. Any model recommendation is well appreciated.
