Bosch Rexroth Offers Drive and Motor Solutions at OTC 2022

Bosch Rexroth will join offshore and marine technology experts to showcase the company’s latest innovations at OTC 2022 on May 2-5 in Houston. Located at Booth #2306, Rexroth and Hägglunds displays will show a range of products and solutions that support the offshore technology sector.

Highlights include the Subsea Valve Actuator (SVA R2), a demo of the latest Hägglunds motors and drive systems and the new power electronics for the eLION product line. Booth visitors will also have the opportunity to connect one-on-one with Rexroth experts to discuss their unique challenges and requirements.

In addition, Bosch Rexroth subsea technology experts Dr. Alexandre Orth and Amadeu Placido will give two presentations at the show. Placido will give a presentation titled “The Digital Twin: Optimizing the System Design from the First Draft to the Cloud” on Monday, May 2, from 2:00-2:22 p.m. CT. Orth will give a presentation titled “Enabling All-Electric Subsea Control Systems Without Compromising Safety – A Case Study Comparing Functional Safety Systems Using Springs or Batteries” on Thursday, May 5, from 2:44-3:06 p.m. CT.

Key booth exhibits at OTC 2022 include:

Subsea Valve Actuator (SVA R2): Visitors will be able to see and touch Rexroth’s award-winning electric SVA R2, winner of the 2022 Spotlight on New Technology Award. The demo will show a process valve connected to a digital twin that can simulate any subsea process automation application.

Axial Piston Pump with Electrohydraulic Control: Rexroth will showcase a variety of aftermarket services and products that maximize equipment availability, including a demo of the Rexroth Axial Piston Pump with electrohydraulic control. The pump is a digital control electronics module with functionality that includes swivel angle and pressure and torque limitation.

Hägglunds Rineer, Atom and CB: Interactive demos will include the Hägglunds CB motor, the Atom hydraulic motor and the Rineer motor to illustrate robust solutions with extreme power-to-weight ratios and full range of torque at the installed power.

Rineer vane motors provide high torque at start and stall and flat torque throughout the entire speed range. The “vane-crossing-vane” design provides optimum power-to-weight ratio, smooth output over a wide speed range and maximum torque at zero rpm.

The Hägglunds Atom comes bundled in an extremely compact design that withstands harsh environments and mounts right on the shaft. Fully marine adapted, the atom is a powerhouse in miniature, unleashing a maximum torque of 13.6 kNm at speeds of up to 400 rpm, ideally suited for marine equipment such as winches, thrusters, dredgers and subsea mining.

Tough and rugged with a wide range of sizes and displacements, Hägglunds’ CB motor gives high flexibility and quick response in heavy-duty marine applications.

Electrification Solutions: eLion is the new high-voltage product line that consists of more than 80 scalable motor variants, three matching inverters, gear units, a modular power distribution unit, onboard charger, DC/DC converter (12V/24V) and cabling (HV+LV).

On display will be one example of the three different power classes featuring Bosch Rexroth's new power electronics, the EDS1-L0400. eLION applications include generator drives, motor-gear-unit combinations for different drivetrain topologies, motor-pump(s) combinations (eLION Sytronix) for different implement and auxiliary topologies, winches, and other accessory requirements.

Industrial Manifolds: Rexroth will showcase a fully assembled and tested manifold with a high quality of functionality and reliability for all industrial applications, from marine applications to oil industries.

Active Heave Compensation: This technology enables greater heave control for winch and crane systems for floating vessels. Rexroth will demonstrate its modularity and show how to retrofit existing systems and new builds.
