Signed and sealed   So that you do not have to depend on promises, we have had branch-specific brakes, couplings and clutches tested and certified for safety-critical and unusual applications by independent institutes. They confirm our claims as to quality and reliability. The Cold Climate Version of our ROBA-stop®-M safety brake sets new standards for pitch and yaw brakes in low- temperature applications. It is the only electromagnetic safety brake certified by Germanischer Lloyd (GL) for applications to -40 °C. These certified pitch and yaw safety brakes work reliably even in the most...

World market leader for electromagnetic pitch brakes ROBA-stop®-M safety brakes   mayr ® power transmission as an internationally leading manufacturer offers safety brakes especially developed and tested for pitch drives with the ROBA-stop®-M brakes. In the pitch drives, the brakes have the important task of securing the rotor blades against twisting after angular positioning through the gear motors. The ROBA-stop®-M brake is available in all sizes and many different versions. The special requests of the customers are standard for us. The power-dense variant „ROBA-stop®-M pitch brake“, on...

Your special requirements for pitch and yaw brakes represent our standard We offer a wide range of supplements and options for our ROBA-stop®-M safety brakes. These facilitate the adaptation of the brakes to the requirements of your applications. The most frequently-requested “special equipment” includes: • Mounting preparation for encoders • Damped rotor • Extended corrosion protection • UL-approved • Microswitch for condition monitoring • Hand release • Continuous shaft • IP66 Continuous shaft: The enclosed design (IP65) is equipped with a sealing plug or cover as standard. A radial shaft...

Pitch brake with high performance density for demanding requirements ROBA-stop®-M for servomotors and regulated AC drives   mayr® power transmission has developed a new application-optimized version of the ROBA-stop®-M safety brakes especially for pitch drives, which place very high demands on performance density and temperatures. Suitable for applications with ambient temperatures up to +90 °C and temperatures at the mounting flange up to max. +120 °C. During emergency stops, brakes can face high demands with regards to friction work. These brakes are perfectly designed for use in pitch...

High level of protection thanks to enclosed construction   Due to the enclosed construction of the applicationoptimized ROBA-stop®-M pitch brake, it can also easily be installed outside the motor housing, in contrast to servo brakes. Schutzarten: ● IP 54 in the standard version ● IP 66 with additional sealing Advantages of the ROBA-stop®-M pitch brake type 891.100.5 ● High level of protection IP54 in standard or IP66 available on request ● High performance density ● Wide temperature range ● Versatile mounting options ● High permissible friction work for emergency stops Product Catalogue The...

Perfect variety for servo pitch drives ROBA®-servostop® safety brakes   The ROBA®-servostop® safety brakes ensure reliable, constant holding torques throughout the entire service lifetime. They feature high performance density, are wearresistant and can also be used in challenging application conditions, such as temperatures of up to 120 °C within the motor. Furthermore, the brakes are characterised through high permitted friction work during dynamic braking: Normally, load mass ratios (load/motor) of 3:1 or smaller are selected for the benefit of good control characteristics and high...

The suitable solution for every application Servomotors are increasingly being used in the pitch sector. However, conventional brakes for servomotors cannot always cope with the high requirements placed on them by pitch applications. mayr® power transmission, on the other hand, offers a multitude of solutions here: Integrated motor brakes ROBA®-servostop® ROBA-stop®-M pitch A-side flanged housing construction designs ROBA®-topstop® ROBA®-alphastop® B-side mounted brakes ROBA-stop®-M ROBA-stop®-M pitch Product Catalogues The detailed Product Catalogues P.898000.V_ _._ _ (ROBA®-servostop®),...
