Even our grandparents knew that double stitching holds better. The principle of redundancy contained therein is one of the core principles of functional safety: If, for example, any component fails, then another component must compensate for the defect. Dunkermotoren applies this principle in DC servo motors (BG series) so that, if necessary, they can also quite safely no longer generate torque. It goes without saying that Dunkermotoren has meticulously complied with all the required standards in the design of the safe circuits. The TÜV Nord has checked the compliance with the standards just as meticulously. Correctness has now been confirmed at the very first attempt and the corresponding certificate for the standard compliant STO function has been issued. Dunkermotoren is a pioneer in the integration of functions in brushless DC motors in the 20...4000 W range. With the certified STO function, Dunkermotoren has integrated a function that makes applications safer, especially in the fields of industrial automation, intralogistics, medical technology and door automation. By combining the motors with components from the modular system, the motors with certified STO can be individually adapted to a wide variety of applications. If necessary, also for the textile industry in the production of double seams. Downloads Pressrelease

Just a few decades ago, fast-rotating saws without contact protection or transport of goods according to the principle "mass has right of way" were common. Today, working even alongside power-packed cobots or gigantic driverless transport systems is safer than with a capricious stapler. The reason for this is functional safety, which systematically helps to avoid dangers with many standards. In the future, Dunkermotoren in the 20...3900 W range will also be available with functional safety, thus contributing to safer products. All motors and external controllers with dPro functionality can be fully integrated with STO (Safe Torque Off). In combination with Industrial Ethernet, STO becomes standard, while retaining the same size. Where energy-hungry and space-consuming mechanical relays are currently still used, fully integrated electronic circuits in Dunkermotoren ensure that motors are switched reliably and torque-free in accordance with relevant standards when required. Since the logic voltage is maintained when STO is triggered, time-consuming referencing after restarting is also eliminated. Thus, a high degree of safety is achieved with a high degree of efficiency. Downloads Pressrelease
