Several manufacturers present products for applications in colder regions as "Cold Climate" versions (CCV). But the CCV marking on a device does not necessarily mean that these products are in fact suitable for cold climate conditions. The CCV product by Mayr power transmission has been certified by Germanic Lloyd (GL) as the only electromagnetic safety brake for applications down to -40 °C.
ROBA-stop-M safety brakes in the Cold Climate Version, installed in a pitch drive.
The definition of cold climate according to GL Wind states that temperatures of below -20 °C can occur. It really depends on the planned location of application and the manufacturer’s specifications to which minus temperatures functional and operational safety have to be guaranteed. In cold climate projects, storage temperatures of -40 °C and below are frequently demanded.
The safety brakes, which are based on the "ROBA-stop-M" series, guarantee minimum downtimes and optimised fail-safe function. In de-energised conditions such as after an emergency stop or power failure, these electromagnetic, spring applied safety brakes are closed and therefore accord with the high safety requirements. Masses and loads are held safely and reliably. On switching on the power, a magnetic field is built up, which attracts the armature disk against the spring pressure to the coil carrier. This releases the brake, and the shaft can then rotate freely.
In comparison to other safety brakes available on the market, the ROBA-stop-M brakes provide a few advantages with regard to the ease of maintenance and operating safety. These include the enclosed construction design, the high Protection, IP54 or IP65, and the high-quality corrosion protection. In addition to the high-quality drive elements, Mayr also provide years of experience in wind power technology based on intensive collaboration with renowned drive manufacturers.Contact:

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
