Danfoss Reverse Displacement Axial Piston Motors

Danfoss Reverse Displacement Axial Piston Motors are medium-power two-position axial piston motors incorporating an integral servo piston. They are especially designed for operation in open-circuit, non-propel applications. These motors are designed with optimized fan drive solutions with the RDM and the new series 45 Fan Drive Control (FDC). When used with the RDM, FDC maximizes efficiencies and performance in an open circuit reversing fan drive system.

These motors have been optimized with regard to options, life, package size, and installed cost. The RDM consists of five unique rotating groups (displacements) in two housings with cartridge mounting flanges. Maximum speeds and maximum applied pressures for each displacement vary. RDM motors are available in numerous sizes ranging from 25 [1.50], 30 [1.83], 35 [2.14], 38 [2.32], and 45 [2.75], with nominal pressure up to 260 and maximum pressure up to 350.

Danfoss RDM is a versatile motor that is utilized in agriculture, construction, forestry, heavy machinery, road building, and wheel loader machines. With the ability to shift over center, these motors combine reversing functionality and the simplicity of open circuit design without the need for additional, external valves. Danfoss Reverse Displacement Motor is just one of the many product innovations and system solutions created by our continuous improvement and re-engineering efforts.
