Danfoss releases new options for reverse displacement motor

Danfoss is pleased to expand on the Reverse Displacement Motor (RDM)

The open circuit piston motor offers reverse circuit functionality without external valves — a hydraulic system product for mobile equipment applications. With wider product options, the RDM can be designed to meet individual needs of customers, increasing function and value. The RDM enables customers to achieve up to 10 percent power savings, a 15 percent average reduction in total system cost, and reduced system complexity.

New RDM options provide customers with more functionality through control options and increased displacement. The compact motor now features the following added options: 38cc, 45cc, Speed Sensor and 24V Valve. The new increased displacements allow the RDM system solution to be available for larger machines. A new speed sensor option provides more precise system efficiency control and the 24V valve enhances the RDM to accommodate additional machine electric architectures.

The Danfoss RDM features a 12V or 24V integrated proportional shifting valve that allows smooth, on-the-go reversing using system pressure. The simplified design of the RDM eliminates the external valves and pressure supply required in typical reversing solutions — and eliminates the cost and pressure losses associated with them.

As previously announced, the RDM is complementary to the Danfoss Series 45 open circuit axial piston pumps, PLUS+1 microcontrollers and DP700 PLUS+1 mobile machine displays, and is ideal for fan drive systems in Tier 4 agriculture, forestry and construction equipment applications. The reverse functionality of the RDM enables the fan to purge trapped dirt and debris, restoring cooling efficiency. Danfoss fan drive packages including the RDM can be tuned to meet the unique cooling requirements of Tier 4 equipment applications.
