Hydraulic motors from Bosch Rexroth offer higher power density

25 September, 2015

With extreme power density and high flexibility, the motors are claimed to be ideal for use in lighter applications, such as injection molding machines in the plastics industry.

Reduced diameter

The new design has seen Rexroth reduce the motor diameter while refining the internal construction and delivering more kilowatts of power per kilo. Full speed and full torque are available simultaneously, and both can be sustained for an indefinite period of time.

The new series is available in four basic models, as well as a wide variety of displacement versions. The torque can be configured via two mechanical interfaces to meet bespoke needs, keeping tight dimensioning and optimisation with hydraulic pumping systems simple.

Built-in ability to withstand shock loads

In addition, the new Hägglunds motor utilises hydraulic radial piston motors with a built-in ability to withstand shock loads. It also features perfect internal symmetry, enabling not only consistent torque throughout the revolution, but a balance of forces, minimising noise and vibration.

David Waldron, business & divisional manager at Bosch Rexroth, said: “The streamlined design of the new Hägglunds hydraulic motor allows engineers to utilise the operational capabilities the market place has come to expect from the Hägglunds series in smaller applications. The new Hägglunds CA 10 to 40 motors not only offer unrivalled power density, but the design improvements have reduced hydro-mechanical losses in the motors, enhancing energy efficiency levels.”
