At the forefront of safety

At the SPS trade fair in Nuremberg from November 12-14, 2024, Stöber will be presenting four new products in addition to efficient drive solutions in hall 3A / booth 446.

At the SPS, Stöber is presenting the new SB6, a drive controller that is suitable for small and medium-sized companies for applications with one to four axes. The new stand-alone solution has numerous functionalities in a space-saving unit. This considerably minimizes the control effort. With its compact dimensions, it fits into control cabinets with an installation depth of 210 millimeters or more. Stöber can equip the SB6 with a control panel upon request. All safety functions can be used up to SIL 3, PL e (Cat. 4). Both linear and rotary synchronous servo, lean and asynchronous motors can be controlled. An SD card that can be easily inserted into the SB6 for application storage is particularly helpful during commissioning. The number of digital and analog inputs and outputs is also a special feature. With this, Stöber offers a drive controller with a full range.

In Nuremberg, visitors also have the opportunity to learn about the proven drive controllers SC6 and SI6 from the 6th generation. The SC6 is a compact stand-alone controller for up to two drive axes with rated output currents of up to 19 A. The SI6 is also slim and dynamic and is suitable for modular technology with rated output currents of up to 50 A. Tasks with more than four axes, such as those found in packaging systems, can be solved economically with this solution. In cooperation with Pilz GmbH, Stöber has developed the safety module SX6 for both controllers, thereby raising the safety level to a new level – in line with the motto “Level up Your Safety”. The controllers can be used in safety-related applications up to SIL 3, PL e (category 4) according to DIN 61800-5-2 or DIN EN ISO 13849-1. Among other things, Stöber has revised the shutdown path of the Safe Torque Off (STO) stop function. At 20 milliseconds, it is now even faster than in products from competitors. The low worst-case response time makes it possible to minimize safety distances. The SX6 module offers the option of automating commissioning with an optional SD card, among other things.

Another exhibit is the KS bevel gearbox, which Stöber now offers not only in a two-stage version but also in a single-stage version under the motto “Power without Compromise”. The series impresses with robust bearing technology and high-quality gearing technology. This makes the KS gearboxes extremely resilient and resistant to tilting. Compared to the two-stage variant, the single-stage version enables a significantly higher speed at the output and a larger ratio range from 200 to 400. The transmissions can also be combined with various Stöber motors in a direct mount. Thanks to the space-saving drive, design engineers benefit from lower weight, high torque and, as a result, increased power density. The full dynamics of the drive can also be used because the gearbox's lower mass moment of inertia is the result of eliminating the motor adapter.

Stöber is also presenting the newly developed racks with double the number of mounting holes. Instead of the usual mounting hole every 125 millimeters, there is a mounting hole every 62.5 millimeters. This doubles the contact pressure of the component on the machine body. There is no need for pinning, but it remains an option thanks to the existing holes. This ensures increased safety and maximum ease of assembly.

What's more, in cooperation with Siemens, the drive specialist is demonstrating its full connectivity to Siemens motion solutions using a digital twin. To make it possible to implement complex applications as well, Stöber supports drive integration via PROFIdrive and PROFIsafe. The model includes various components from the drive specialist, such as helical-bevel and planetary geared motors as well as drive controllers from the SC6 and SI6 series. Siemens provided the software needed to supply the CAD data and for the actual simulation on a separate display.
