Bosch Rexroth introduces hydraulic motors with unmatched power density

Bosch Rexroth has powerfully repackaged the compact series of Hägglunds hydraulic motors. The new Hägglunds CA 10 to 40 motors are far smaller and lighter, yet nothing has changed in their output. This gives them unmatched power density, with the unique ability to deliver full torque and full speed simultaneously.

The new motors will extend the Hägglunds compact series downward to 10 Nm/bar. With extreme power density and high flexibility, they will make hydraulic direct drives the optimal choice in lighter applications.

Initially, the focus for the Hägglunds CA 10 to 40 series will be injection molding machines in the plastics industry. These machines represent a large portion of the demand at 50 Nm/bar and below. Additional industries and further applications are set to follow in the very near future.

Unequalled power density

To achieve the unmatched power density of the CA 10 to 40 motors, Bosch Rexroth has reduced the motor diameter while refining the internal construction. These changes have no effect on reliability or output, which is why the motors deliver more kilowatts per kilo than any other. Full speed and full torque are available simultaneously, and both can be sustained for an indefinite time.

“In designing the series, we’ve used principles similar to those in our proven Hägglunds CBM motors,” says Benno Birke, Senior Vice President Technical for Industrial Hydraulics Controls and Cylinders. “The new CA 10 to 40 motors provide the same power as before but with far less weight – up to three times less than a competitor solution.”

Energy-saving productivity

For customers, the power density means energy and production efficiency. Compared to competitor solutions, CA 10 to 40 motors provide 10-15% more torque for the amount of energy put in. “Because the hydro-mechanical losses in our motors are so much less, they consume less energy particular in the upper speed range,” says Birke.

Further efficiency comes from the flexibility in the series, which includes four basic models and a wide variety of displacements. Fourteen configurations in small torque steps allow tight dimensioning, as well as full optimization in relation the hydraulic pumps. The configurations are achieved using just two mechanical interfaces, which means easy adaptation is also possible.

The full range of hydraulic advantages

Combined with the unbeatable power and flexibility of the CA 10 to 40 series are the unique benefits specific to hydraulic radial piston motors. These include a built-in ability to withstand shock loads, as well as perfect internal symmetry. The latter ensures consistent torque throughout the revolution, as well as a perfect balance of forces that minimizes noise and vibration.

From unique power density to high energy efficiency, the new Hägglunds CA 10 to 40 series means powerful benefits in plastics and beyond.

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.
