Energy-efficient automation up to the multi-megawatt class

Energy-efficient and safe, even at high levels of power: Large Electric Drives from Rexroth.

New Large Electric Drives from Rexroth for 110 kW to 4 MW

Greater energy efficiency and safety increasingly determine the selection of drives, even at high levels of power. With the newly developed Large Electric Drives, Bosch Rexroth now offers a fine-scaled product range of very strong drive solutions from 110 kW to 4 MW for these applications. This corresponds, for example, to the drive power that is necessary to pull a freight train which is up to 700-meters long. The new drives open up numerous opportunities to users for improving energy efficiency, such as through power regeneration. At the same time, the Safety on Board safety functions integrated in the drives ensure the optimal protection of man and machine.

With forming and plastics machines, metallurgy or materials-handling equipment, a high degree of force is often necessary, so a high degree of drive power is required. Even so, end users expect more energy efficiency in order to reduce operating costs. With the new Large Electric Drives from Rexroth, machine operators can reduce power consumption up to the multi-megawatt range and thereby increase productivity.

The new Rexroth drives use the expertise of the Rexroth 4EE system. They are optimized in terms of efficiency, function according to demand, and offer numerous opportunities for energy recovery. In multi-axis systems, the drives enable the use of braking energy within the drive assemblage via a DC-bus coupling. Moreover, excess energy can be fed back into the network. Users can capitalize on further savings potential with concepts for static and rotational energy storage as well as the Smart Energy Mode software function. In addition, air and liquid cooling systems offer different ways of dissipating and using waste heat. Rexroth offers the Large Electric Drives in performance degrees of 110 kW to 500 kW. Through a parallel connection of up to 8 devices, mechanical engineers achieve a drive power of up to 4 MW.

The drive-integrated Safety on Board safety features ensure standard-compliant machine safety. This simplifies engineering and enables integrated modularization, because a higher-level control unit is not necessary for safety. Large electric drives also have the certified safety functions Safe Torque Off and Safe Motion.

The optional integrated Motion Logic provides a variety of application-specific technology functions for peripherally coordinated movements. As a result, they solve even complex motion tasks with up to 10 axes. This allows machine manufacturers to automate economically. The decentralized approach relieves the higher-level control unit, or even makes it unnecessary in many cases. With the consistency of the firmware functions as well as of the control unit parts, the Large Electric Drives offer all the functions of the IndraDrive family. This simplifies the combination of drives throughout the entire output range from 100 W to 4 MW. With Multi-Ethernet and Multi-Encoder interfaces, they fit seamlessly into various automation architectures.

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, Factory Automation, and Renewable Energies to develop innovative components as well as tailored system solutions and services. Bosch Rexroth offers its customers hydraulics, electric drives and controls, pneumatics, gear technology, and linear motion and assembly technology all from one source. With locations in over 80 countries, more than 37,500 associates generated sales revenue of approximately 6.5 billion euros in 2012.
