Small brakes with high performance density
The safety brakes by mayr® power transmission guarantee reliable, constant holding torques over the entire service lifetime. They distinguish themselves through compact dimensions and are not only very lightweight, but also very fast when it comes to magnetic actuating. Furthermore, they feature high performance density, are wear-resistant and can be used even in demanding ambient conditions, for example at temperatures within the motor of up to 120°C. The brakes are also characterized by the high permitted friction work with dynamic braking actions: For servo drives, normally load mass ratios (load/motor) of 3:1 or smaller are selected for the benefit of good control characteristics and high dynamics. On the ROBA®-servostop® brakes, high permitted friction work and friction powers mean that load mass ratios of 30:1 and more are possible. The simple and robust construction of these safety brakes allows simple, quick and reliable installation: The operating air gap is factory-specified. In contrast to permanent magnet brakes, exact axial positioning on the motor shaft is not necessary. The ROBA®-servostop® brakes always work accurately and reliably; the magnetic air gap is not influenced by the mechanical installation situation. Every single safety brake, which leaves the plant, is subjected to a 100% inspection after final assembly and adjustment summarizes. All measured values determined are archived together with the respective brake serial number in our electronic database. This ensures 100% traceability – as reliability and safety do not allow for compromises.
