STÖBER Antriebstechnik GmbH + Co. KG
About us
At home in the world of demanding motion.
For over 90 years, STÖBER Antriebstechnik has stood for excellent, highly efficient drive solutions. What began as a family business in 1934 is now an internationally successful technology partner for machine manufacturers in a wide range of industries.
Our strength: tailor-made drive systems consisting of gearboxes, motors, cables and drive controllers – and above all, the people behind them. Around 1,000 employees worldwide are working together at STOBER to shape the future of drive technology. We are united by our enthusiasm for innovation, our sense of responsibility and our commitment to developing technology that really makes a difference.
Our drive systems, developed and produced in-house, are modular in design and freely scalable – for tailor-made, compact and powerful machine concepts and individual systems.
Our passion for drive technology drives us to continuously develop ourselves and our products. We take inspiration from practical experience, take customer requests seriously and are constantly looking for even better solutions.
Products
Everything from a single source
The STOBER drive system consisting of gear units, motors and drive controllers has a modular design and is freely scalable – for tailor-made, compact and powerful machine concepts. It can therefore be adapted to your individual requirements and combined as needed in nearly all industries and application areas.
High-efficiency drive controllers with safety technology
Whether for high-performance systems, highly efficient multi-axis applications or compact modules – the 6th generation from STOBER always has the right drive controller on hand. Benefit from four series of our drive controllers that can be combined with each other: SC6 for compact systems, the slim and dynamic SI6 for multi-axis drive systems, the flexible SD6 for all kinds of tasks, and the new, universal SB6 for a variety of applications. Every drive solution has its own unique character. And we have the matching drive controllers! Whether drive-based or control-based – we have universal and flexible solutions for any kind of motion control. The shortest possible recovery times from fast set value changes and load jumps are the reason why our drives have such high dynamics. There is also an option of connecting the drive controllers in a DC link for multi-axis applications, which improves the energy footprint of the entire system. And speaking of energy, all STOBER drive controllers comply with energy efficiency class IE2 in accordance with EN 61800-9-2.
Hybrid cable One Cable Solution OCS - Connected at a distance
STOBER has further developed its One Cable Solution (OCS) in cooperation with encoder manufacturer HEIDENHAIN and launched the next generation on the market. With the future-proof HEIDENHAIN EnDat® 3 protocol, the new hybrid cable can reliably connect motors and drive controllers at a distance of up to 100 metres. The user receives a complete system consisting of synchronous servomotor, cable and matching drive controller. To connect a motor to a drive controller, two cables are usually used: one transmits the encoder data, the other the electrical power. With OCS, a hybrid cable takes over both tasks. With small weak points: If the encoder and drive controller are further than 15 metres apart, the data can no longer be transmitted without interference. In this case, one output choke per cable becomes necessary. This component is expensive and requires additional space in the control cabinet. Since chokes generate heat, appropriate cooling is required. STOBER has solved these problems in cooperation with HEIDENHAIN: They have further developed the already existing STOBER single-cable solution and optimised it especially for highly dynamic applications in drag chains.
STOBER goes PROFIdrive and PROFIsafe
STOBER has enhanced its SC6 and SI6 series drive controllers with additional PROFINET functions. Thanks to the redeveloped SU6 module, the controllers offer an attractive solution for STO and SS1-t via PROFIsafe. In the area of motion control, STOBER now supports a wide range of application classes in accordance with the standardized PROFIdrive device profile. A highlight: The communication interfaces of the drive controllers are now also PROFINET-certified.
None are more compact with this versatility: Planetary servo geared motors.
With the new generation of planetary servo geared motors, STOBER has developed drive solutions that are the most compact on the market in terms of versatility! Benefit from a 65% increase in power density and – by leaving out a motor adapter – get the most out of the dynamics of your drive.
Designed to be absolutely practical: Helical bevel servo geared motors.
In this series, helical bevel gear units and synchronous servo motors form a compact unit featuring very convenient installation dimensions and a high power density. The result is an extremely wide range of efficient design options for the packaging and machine tool industries as well as for automation and robotics.
Planetary gear units paired with highly efficient helical bevel gear units. When the motor gets in your way: Right-angle planetary gear units.
Our premium planetary gear units paired with our high efficiency helical bevel gear units. The result: STOBER right-angle planetary gear units! If the motor in coaxial design represents an interference contour, the combination of a STOBER planetary gear unit with a bevel gear unit is the best choice for the highest demands on dynamics, backlash stability and robustness.
Rack and pinion drives from STOBER – From full rotation into linear motion
With the innovative concept for rack and pinion drives, STOBER has developed a compact, easy-to-use system with process reliability that is precisely tailored to applications in machine tools, automation and robotics. By combining it with STOBER’s planetary or helical bevel gear units and directly attached servo motors, users receive a wide variety of compact, highly dynamic drive solutions from a single source. The complete gear units are ready for immediate use and no assembly work is required at all.
E stands for economy
STOBER has developed its planetary gear units of the PE series – where E stands for economy – even further. The user gets an extremely economical variant of the STOBER planetary gear unit with significantly increased performance and typical STOBER helical gearing. This gearing ensures low noise development and optimal smooth operation. This is a unique feature on the market in this price and product class. Combined with the STOBER IE5-class Lean motor with direct attachment, the user receives a drive that is economical, while still being extremely energy efficient.
