MAKING MODERN LIVING POSSIBLE Data Sheet H1-The new Generation of Hydrostatics 250 cm3 Bent Axis Variable Motor For more than 40 years, Danfoss has been developing state-of-the-art components and systems for mobile machinery used in off‑highway operations around the world. We have become a preferred supplier by offering the best of what really matters: The hardware inside your vehicle application. H1 - our new generation of servo-controlled hydrostatic pumps and bent axis variable motors is no exception. The H1 product is built around an advanced control and available in a wide range of displacements. It is designed for quality and reliability and offers expanded functionality, greater total efficiency, and easy installation. All H1 control and sensor options are PLUS+1® Compliant. PLUS+1® allows you to rapidly develop and customize electronic machine control. It opens up the future by combining machine controls and diagnostics in an integrated operating network.
