Bosch Rexroth updates Hägglunds CA hydraulic motors

March 24, 2015 - Bosch Rexroth updates Hägglunds CA hydraulic motors, making them smaller and lighter, yet nothing has changed in their output.This gives them good power density, with the ability to deliver full torque and full speed simultaneously.The motors 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.

To achieve the 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.
For customers, the power density means energy and production efficiency. CA 10 to 40 motors provide 10 to 15 percent more torque for the amount of energy put in.

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.

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.
