Dürr Systems GmbH and Bosch Rexroth AG have decided to extend their close cooperation in the development and serial use of energy-efficient drive solutions for another three years. This means a continuation of their successful collaboration that has existed even before the development of the newest generation. As compared to the old painting and sealing robots, the new robots’ energy demand has decreased by up to approx. 30 percent. This is owed not only to more compact electric servo controllers for servo drives and the use of new Rexroth pneumatic controllers for painting processes, but also to the company switching to the Ethernet-based automation bus sercos.

Automobile manufacturers around the world are introducing energy-efficient production processes to reduce CO2 emissions. Dürr Systems, the worldwide leader in painting systems, supports this objective by developing a new, energy-efficient control and drive technology for painting robots. Thus the energy demand decreases by approx. 30 percent.

Together with Bosch Rexroth, Dürr Systems has designed the entire drive and control solution in an application-oriented way. In this context, the company used Rexroth’s universal “Rexroth for Energy Efficiency” system. “In extensive mechatronic simulations, we have attuned components of electric drive technology and pneumatics that are optimized in terms of efficiency precisely to this application,” says Dr. Steffen Haack, Senior Vice President Sales, Industry Sector Factory Automation of Bosch Rexroth AG. “Practical experiences from several paint factories have confirmed the previously determined increase in energy efficiency.”

The manufacturer-independent automation bus sercos takes over the entire motion and process communication in the new robots, thereby reducing the number of communication systems from previously three to now one. “Our close cooperation with Rexroth has made this transition very easy for us and has considerably simplified the control architecture,” emphasizes Dr. Hans Schumacher, Managing Director at Dürr Systems. The use of compact servo controllers reduces power loss and – together with the switch to the automation bus sercos – decreases the volume of control cabinets. Air-conditioning devices are no longer needed thanks to the low cooling requirements, and the temperature is controlled by means of an energy-efficient fan drive. “The ones to benefit are our customers, because now they can save up to 30 percent in energy,” says Schumacher.

Dürr and Rexroth intend to continue this partnership for the further development of electric and pneumatic drive solutions for energy-efficient robots in the years to come. In late February, the two companies signed a three-year framework agreement.
