Danfoss Introduces Unprecedented Reverse Displacement Motor (RDM)

July 1, 2014 By Garrett Harmon Leave a Comment

Danfoss is pleased to introduce the innovative Reverse Displacement Motor (RDM). The
open circuit piston motor offers reverse circuit functionality without external valves — an
unprecedented hydraulic system solution for mobile equipment applications. 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.

The RDM is built on the proven efficiency and reliability of the L/K Axial Piston Motor from
Danfoss. The compact motor features a 12V integrated proportional shifting valve that allows
smooth, on-the-go reversing using system pressure. This simplified design eliminates the need
for additional components, cost and pressure losses associated with the external valves and
pressure supply necessary in typical reversing solutions.

Complementary to the Danfoss Series 45 open circuit axial piston pumps, PLUS+1® microcontrollers and DP700 PLUS+1 mobile machine displays, the RDM 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.

“At Danfoss, we’re dedicated to being our OEM’s strongest partner in mobile hydraulics,” said
John Heller, Product Marketing Manager at Danfoss Power Solutions. “We understand how much
OEMs have invested in meeting Tier 4 emissions regulations, and how much their customers
value power savings. We know OEMs depend on our expertise, and we’re pleased to offer the
Reverse Displacement Motor, an industry-exclusive solution that conserves horsepower while
minimizing system cost and complexity for the OEM.”

In addition to fan drives, the RDM is well-suited for a full range of applications with the need for reversing capability, including conveyors, auger boring machines and directional drills.

In fan drive applications, the RDM is designed to protect the equipment. In the event of a
controller or electrical failure, the fault position of the motor is biased to maximum forward
speed, enabling the fan to maintain the integrity of the cooling system on the machine.
Around the world, mobile equipment manufacturers rely on Danfoss expertise for the most
innovative work, propel, control and steering solutions. Working in partnership with customers, Danfoss provides high-value, high-performance components for a broad range of mobile equipment applications. Danfoss designs, manufactures and sells a complete range of engineered hydraulic and electronic components including hydrostatic transmissions, mobile electronics, orbital motors, steering components and PVG proportional valves.
