Rexroth IndraDrive ML: Now also for higher voltages and marine applications

Rexroth IndraDrive ML

Intelligent, universal, and efficient: Electrical drives IndraDrive ML by Rexroth are suitable for complex motion tasks in industry as well as in marine and offshore applications.

Universal inverter from 110 kW to four MW output simplify high drive power engineering

With additional variants for the voltage range from 525 V to 690 V, Rexroth expands the range of uses of IndraDrive ML drives for outputs up to four megawatts. International and application-specific certifications reduce engineering effort for universal use in industrial machinery and equipment as well as in marine and offshore applications.

Wherever machinery and equipment requires drive power of several hundred kilowatt up to the megawatt range, the trend is toward higher supply voltages up to 690 V. The current is reduced due to the higher voltage and smaller wire sizes can be used. New facilities use almost exclusively devices with 690 V supply voltage, in particular in the paper industry, metallurgy, in marine and offshore applications as well as in energy generation. For these requirements Rexroth has developed additional variants of Large Electric Drives IndraDrive ML for the voltage range from 525 V to 690 V. They supplement the proven product line for supply voltages from 380 to 500 V. The space-saving, modular universal inverters generate drive power between 110 kW and 500 kW per device, and in parallel connection of up to eight devices up to four MW.

Regardless of the supply voltage, IndraDrive ML is already certified for industrial application pursuant to CE, UL and CSA. This reduces the engineering and documentation effort for global use. All product lines are currently in the process of being approved by the ship classification authorities GL., DNV, ABS and LR. so that they can be used as “type approved” in typical marine and offshore applications, e.g. anchor and net winches or for hoist, slewing, and luffing drives for ship cranes.

IndraDrive ML can be operated as supply or frequency changer or as motor inverter. This minimizes variants, simplifies handling, and reduces storage costs for OEMs and end users. The universal inverters are particularly suitable for complex multi-axis applications. Drive-based Motion Logic solutions regulate synchronized movements via their own intelligence, even without higher-level control units. The certified safety technology “Safety on Board” also integrated in the drives reduces engineering effort for standard-compliant machine safety. With a multi-Ethernet interface for all common communication protocols and one multi-encoder interface, the drives seamlessly integrate even into heterogeneous automation environments.

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.
