The trend is clear: the future belongs to compact and robust direct drives. With the SEK160 hollow-shaft motor feedback systems SICK has perfected the concept of the direct drive. The SEK160 with holistic scanning can be mounted directly onto the drive shaft without any mounting tools. A toothed belt and transmission elements such as gearbox or coupling are no longer necessary. The simplified, compact design is wear-free and hence helps to reduce maintenance costs. Since no ball bearings are used either, heat generation is drastically reduced. The minimal dimensions allow for reduced space requirements and also make the device lighter, thus allowing for efficient space utilization. The SEK160 motor feedback systems were developed specifically for direct drives and support the advantages of direct drives all along the line.
