At the Euroblech in Hanover, Baumüller – an experienced supplier of drive and automation solutions – will be demonstrating how smart drive technology, combined with intelligent technological solutions, reduces production costs. The supplier of drive and automation solutions is exhibiting a working mini servo press at its stand. Manufacturers and users of metal-forming machinery will also be treated to a LIVE demonstration of a drive combination comprising a DST2 high-torque motor from Baumüller and a Servox® gearbox from Nidec Desch. You can find Baumüller at the trade fair from October 20 to 23, 2026, in Hall 27 at Stand C155.
Servo presses offer significant advantages over conventional mechanical presses, such as increased productivity and higher product quality. They also offer users a huge amount of flexibility. For example, the motion profile during the forming process can be adjusted more flexibly, and processes can be optimized in terms of cycle time, tool wear and energy consumption. In addition, the number of wear parts is reduced, which means less maintenance is required.
Baumüller’s high-performance servo press system solution comprises a DST2 high-torque motor, a b maXX mains inverter, a b maXX servo drive, control technology, and a comprehensive software package.
Greater flexibility, less wear: The Baumüller servo-press system solution combines the DST2 high-torque motor, the b maXX servo drive, the b maXX mains inverter, control technology, and software in a complete package
To take full advantage of the flexibility offered by the forming process, a flywheel press can also be brought up to the latest standards by retrofitting its drive and control systems. This typically comes at significantly lower cost – and often with a faster turnaround – than purchasing a new machine. A mechanical flywheel press can generally be converted into a servo eccentric press with minimal design modifications. Once the existing drive system has been dismantled and the mechanical components have been thoroughly inspected, the DST2 high-torque motors can usually be integrated into the existing gearbox without any problems. Use of b maXX servo drives and Baumüller’s comprehensive control package enables the press to be operated flexibly and dynamically right from the start. Since numerous wear parts such as the clutch, brakes, and V-belts are also eliminated, the
modernized machine requires significantly less maintenance.
Modernization rather than replacement: Converting a flywheel press into a servo press increases flexibility, reduces maintenance requirements, and saves time and money compared with buying a new machine
The choice of which drive system is most appropriate depends primarily on the product being manufactured on the machine, and therefore on the machine’s configuration. The flexible range of b maXX servo inverters also enables an intelligent drive architecture through various combinations. As a result, presses equipped with servo drive technology not only deliver high process quality but also offer the added benefits of reduced energy consumption and lower energy peaks. At the heart of the drive system is a common DC link. It connects the b maXX grid-connected inverter – a unit for feeding power into and back from the grid – to the b maXX
servo inverter. The DC link connection enables larger amounts of energy to be stored in the DC link capacitors. This compensates for process-related peaks, meaning that the electrical connection capacity can be designed to be significantly lower without energy spikes. This reduces the connected load and the associated costs.
Another advantage of the DC link connection is the use of recovered energy during the forming process. Thus, certain process movements not only draw energy, but also provide braking energy, for example during deceleration following the forming stroke. The DC link makes it possible to buffer – that is, temporarily store – the energy generated in this way and make it available for the next stage of the process. This reduces the press’s actual energy consumption.
Furthermore, the device gives the drive system an additional advantage in terms of motor performance. It boosts the DC link voltage from 400 to 760 volts, thereby shifting the motor characteristic curve upwards. This expands the available speed range and means that the motors can be made smaller for many applications.
Finally, the b maXX grid-connected inverter can feed surplus energy from the shared DC link back into the supply system. This saves energy and reduces costs. By feeding back the excess energy, braking resistors can also be made smaller or eliminated. This saves space and reduces the cost of the control cabinet.
