Industrial Hydraulic Motors have power density-optimized design.

Press Release Summary:

Hägglunds CA 10–40 motors can simultaneously deliver full torque and full speed, both of which can be sustained indefinitely. Available downward to 10 Nm/bar, motors suit injection molding machines in plastics industry. There are 4 basic models and various displacements; 14 configurations in small torque steps allow tight dimensioning as well as full optimization in relation to hydraulic pumps. Facilitating adaptation, configurations are achieved using 2 mechanical interfaces.

Bosch Rexroth Introduces Hydraulic Motors with Unmatched Power Density

Extreme power density and high flexibility make hydraulic direct drives the optimal choice in lighter applications

Bosch Rexroth has powerfully repackaged its compact series of Hägglunds industrial 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.

Unequaled 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 Bengt Liljedahl, Technical Product Manager. “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 to 15 percent more torque for the amount of energy put in. “Because they weigh so much less, they use less energy in the high-speed range,” says Liljedahl.

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 to 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.
