MAKING MODERN LIVING POSSIBLE Data Sheet Reverse Displacement Motor (RDM) Open Circuit Piston 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. The Reverse Displacement Motor (RDM) is designed for use in mobile open circuit applications. It offers reverse functionality without external valves, and provides system robustness with available anti-cavitation and shock valves. The RDM uses the existing and proven technology of the Danfoss L/K motor. These motors have been optimized with regard to options, life, package size and installed cost. The RDM is a two-position reversing motor, with smooth, shift-on-the-go capability. The integrated proportional shifting valve uses system pressure. It allows reversing functionality without external valves and external pressure supply. yy Designed for Durability and Flexibility –– Especially designed for open circuit applications with a need for reverse functionality –– Five displacements allow the optimum selection of a hydraulic motor to fit your application –– Reliability - uses existing and proven technology of Danfoss L&K motors yy Wide Range of Options –– Fail Safe: Without control signal, the motor is biased to maximum forward speed –– Damped shifting from reverse to forward –– Shaft options with dust seal protector –– Integrated system protection - anti-cavitation and shock valve –– High capacity bearings to withstand axial fan yy Installation and Packaging benefits forces –– Short and compact –– Complimentary to Danfoss Series 45 open circuit –– High efficiency - nine piston rotating groups with pumps with electronic proportional control an 18 degree maximum angle –– PLUS+1 micro controller with fan drive software –– Uses system pressure for shifting – no external available pressure supply needed –– This motor has the capability to be held at or –– Integrated shifting valve enables reversing – no near neutral for potential added system power external valves needed - less hoses - less losses savings or faster heating of the engine at start-up - simple and clean installation –– Variety of porting options allow for easier system –– 12Vdc and 24Vdc valves configurations system configurations - Metric O-Ring boss - SAE O-Ring boss - Split flange –– A speed sensor is available
