10 ROBA -diskstop Electromagnetic solution for safe small wind turbines acc. IEC DIN EN : The electromagnetic caliper brake ROBA -diskstop is like the ROBA-stop -M designed as a safety brake according to the fail-safe principle and is suitable as a brake for the main drive of small wind turbines with or without pitch system. By mounting several calipers onto a disk or by enlarging the disk diameter, very high braking torques can be achieved. Experience has shown that especially in systems without pitch system, very high friction work values can occur due to permanent wind loads and frequently standard friction linings are not sufficient. In mayr s own Research and Development department, special sintered linings have been specified. Reliable brake dimensioning is essential here. Please request our questionnaire on brakes for small wind turbines. Via correct wiring, e.g. by using mayr s in-house developed electronic components, the electric holding performance of the brake can be reduced significantly in order to optimize the efficiency of the system Function 0 The ROBA -diskstop brake is designed as a spring applied, electromagnetic safety brake. Spring applied function: When the brake is de-energised, the thrust springs (2) push the armature disk (3) against the brake disk (Fig. ). The brake disk is held between the friction pads (4). Electromagnetic function: Due to the magnetic force of the coil in the coil carrier (), the armature disk (3) is attracted against the spring force to the coil carrier (). The brake is thereby released and the brake disk can rotate freely.

11 Consistent energy efficiency GREEN Tech Optimum construction saves resources and reduces the coil capacity On electromagnetic ROBA-stop safety brakes, the magnetic flow is optimised by constructional design and material selection so that the required magnetic traction force can be achieved with as low a coil capacity as possible. Optimum dimensioning of the magnetic coils and construction designed to aid magnetic flow are important aspects for energy savings. 75 % lower energy requirements in operation due to lower voltage requirements Operating the brake provides far larger potential for making savings than the construction. Up to 75 % of the energy can be saved via optimum control of the brake. ROBA-stop safety brakes are generally dimensioned so that they will release at coil nominal voltage even with maximum permitted wear of the friction linings. After release, a far lower voltage is quite sufficient to hold the brake open reliably. This physical effect is used consistently on ROBAstop brakes by controlling them using the ROBA - switch. Due to the reduction to 50 % of the coil nominal voltage, the electrical power is reduced and therefore the energy requirement by 25 %. Responsible environmental protection is deeply rooted in our company philosophy. We develop our products according to the maxim of highest possible power density. This saves material and energy over the entire lifetime of the product. Of course we also manufacture using environmentally-friendly processes. This is confirmed by our DIN EN ISO 400 certification.
