servo hydraulics in machines combines the best of two worlds: the benefits of hydraulic power transmission with the advantages of servo drives. Baumüller offers one Calculator, which calculates the potential energy savings when switching from hydraulics to servo-hydraulics. details about it and Products various manufacturers of the technology can be found below:

Calculate the advantage of servo hydraulics online in just three steps
26.01.2022/XNUMX/XNUMX | With a change from Hydraulic System on servo-hydraulic drives, more than 50% energy (kWh) per cycle can be saved with a hydraulic machine, depending on the application. Baumüller presents an energy calculator that calculates the savings in just three steps. In it, the energy consumption of a classic fixed displacement pump becomes one servohydraulic pump faced.
After entering the duration, pressure and flow rate of the individual components, hydraulic energy, power consumption per cycle and the annual energy consumption calculated. The consumption values of classic constant pumps and servo-hydraulic pumps from Baumüller are displayed next to each other in an overview. At the end of the comparison, the CO₂ footprint is shown graphically based on energy savings, CO₂ savings and percentage savings.
The summary of the results and a Advice can be provided upon request be requested in a further step. The entered data can then be used directly without further input for the specific component design.

Combining hydraulics and servo technology
Classic hydraulic applications have many advantages: The hydraulics ensure a high power and performance density. A large number of drives can be controlled with just one drive. the Drive Elements are robust and comparatively inexpensive. In many cases, such as with hydraulic and hybrid injection molding machines and presses, servo-hydraulic drives can further improve the efficiency and performance of the machine.
Servo-hydraulic machines combine the advantages of fluid technology with the benefits of servo Drive Technology: High power densities, compact drive units as well as cost-effective, robust drive elements meet Speed control with precision and dynamics. This significantly reduces the energy consumption of the drive system. In addition, there is a higher level of accuracy, shorter cycle times and less noise.
Electrically controlled, servo-hydraulic compact axes
29.06.2021 | Bosch Rexrothis expanding its range of electrically controlled, servo-hydraulic compact axes by taking over an extensive technology package. So far, these have mainly been used in the industrial sector. So far, the focus has been on axles in the power class from 10 kW. With the technology now taken over from EH-D and Onovum, the portfolio is being expanded into the range below 10 kW.
The compact axes from Onovum and EH-D are used in various industries where linear movements with great force are required. Typical applications are plastic machines or presses, power plant technology, steel industry, Metalworking, refrigeration, Food industry or Mobile applications.
The servo-hydraulic axes offer some special technical features: Your internal gear pumps are suitable for 4-quadrant operation, i.e. operation possible in both directions as a drive or Brake. The oil flowed through synchronous motors allow targeted heat dissipation and thus extended operating ranges without secondary cooling. In addition, the compensators specially developed for the EH-D compact axes serve to compensate for differential volumes and internal leakage flows or temperature expansions of the fluid.
Energy-efficient servo pump with self-lubricating internal gearing
22.10.2019 | Combined with this power steering pump Baumüller the advantages of hydraulic power transmission with the benefit of electric servo drive technology. The intelligent control of the drive and the lower energy consumption of the components, especially in the partial load range, result in a highly energy-efficient yet economical solution.
The advanced Power steering pump is with an internal toothing directly on Motor attached, which has the advantage of a shorter installation length and consequently a smaller footprint for the machine. Direct attachment also means that several mechanical parts are no longer required.
Another advantage concerns the intelligent use of hydraulic oil as a lubricant for the gearing. The existing connections on the motor and constant pump allow the hydraulic oil to be fed back into the circulatory system and thus the leakage flow of the pump can be used for permanent lubrication of the gearing. There is no need for grease lubrication of the internal gearing, which is due on average every 3000 operating hours. The machine can produce without interruption.
Most compact Atex pressure switch in its class for hydraulics
The structural change offers another customer benefit. Since the connections are drilled on both sides, the motor can be used depending on the application installed vertically or vertically will. The motor position can therefore be freely selected and adapted to the respective machine design.
