With high power density and flexibility, they will make hydraulic direct drives the optimal choice in lighter applications. To achieve the unmatched power density of the CA 10 to 40 motors, the company 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.” 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 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. The configurations are achieved using just two mechanical interfaces, which means easy adaptation is also possible. 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.
