There's more: Energy efficiency will continue to rise with integrated production

More energy efficiency under Industry 4.0 conditions

Dr. Karl Tragl, Chairman of the Executive Board at Bosch Rexroth AG

The state of the art: It is now common for machines to recover the power normally wasted as heat by braking and make it available to other motors for accelerations. As Industry 4.0 becomes a reality, it will be possible to transfer energy-saving concepts like this to entire factories, through intelligent integration of all areas of production. According to Dr. Karl Tragl, Chairman of the Executive Board at Bosch Rexroth AG:

“In Industry 4.0, the drivers of improved energy efficiency available today — efficient components, demand management, recovery, and efficient design — will remain in place with the added benefit of developing and delivering much more power. For example: intelligent components and Industry 4.0 machine network modules equipped with sensor technology will generate a multitude of data and information. Analyzed systematically, energy efficiency increases significantly within the overall value creation network.

At the same time, machinery manufacturers will also use this intelligence to operate uncontrolled motors in pumps and fans on demand, according to their needs. The use of model-predictive feedback controls and cloud-based simulations open up new possibilities to completely maximize energy efficiency potential at the plant level.

Meanwhile, the current state of the art technology draws energy once from the power supply into the machine for multiple uses. Thanks to integration, this concept can be transferred to entire factories in the future. An intelligent exchange of energy among machines offers enormous potential to reduce CO2 emissions and save operating costs.

And finally, in the concept development phase for new machines, builders in the future will be able to analyze and optimize all components of entire energy flows using virtual machine simulations.

With the drivers described in our Rexroth 4EE System (for Energy Efficiency), we can increase energy efficiency in industrial processes today. But we all know that climate objectives present a tremendous challenge. The smart factory will help us significantly transform and elevate our ability to produce in a way that saves the most resources possible.”

Intelligent hydraulics for increased availability

Connected hydraulics increase the availability of machinery and plants through condition monitoring and predictive maintenance. For this purpose, Rexroth offers scalable solutions, from individual units with local evaluation to the complete, cloud-based monitoring of large plants. Sensors measure all relevant operating conditions and software detects wear before it leads to failure. Retrofitting kits also economically integrate already installed plants into these concepts.

Linear motion, short time to market

Stand-alone linear axes are the trend. The combination of electrical drive unit and mechanical or hydraulic cylinder reduces installation space and engineering time and combines our specific professional knowledge in one system. With ready-to-mount and i4.0-enabled solution packages, Bosch Rexroth is in line with the current market requirements regarding electrification, digitalization and monitoring as well as condition-based maintenance. The uniform control and drive concept which is used in the different technologies serves as a basis for a short time to market and the economical implementation of hybrid solutions.
