RE Danfoss Orbital Motor

Danfoss RE orbital hydraulic motor is a low-speed and high-torque hydraulic motor that provides reliable rotary force for medium-duty machines and equipment. The motor converts hydraulic energy into mechanical rotation to enable the machinery to accomplish tasks requiring controlled motion and torque. The RE series is an optimal combination of performance, durability, and affordability, which makes it a good choice for medium-duty applications requiring reliable hydraulic power. Additionally, its design makes it well suited for applications working at low flows and high pressures.

Danfoss RE hydraulic motor employs roller-gerotor technology and valve-in-rotor technology for distributing hydraulic oil and producing shaft rotation. Pressure compensated balance plate is used in the motor to enhance the volumetric efficiency, especially under low flow rate and high pressure conditions. There are different bearing types available in this series, which include standard bearing, medium-duty bearing, heavy-duty bearing, and compact heavy-duty bearing. Some of the bearing types are also used for wheel drive applications.

There are many applications that may be fitted with the Danfoss RE hydraulic motor such as medium duty wheel drives, augers, mixers, winch drives, swing drives, grapple heads, feed rollers, and broom drives. It depends on the type of machinery where the motor may be used. High starting torque ensures that the machinery starts moving from a stationary position and the compact design allows installing this motor in systems that have limited space available for installation.

The proper care and maintenance play a significant role in ensuring the reliable operation of a Danfoss RE orbital motor. The presence of contaminated hydraulic oil, improper filtration of hydraulic fluid, excessive heat and incorrect setting of the pressure may contribute to increased internal wear and reduce the performance of the motor. Some symptoms may include low torque, slow rotating speed, strange noises, oil leaks and overheating.

Rexton Hydraulic offers hydraulic motor supplies, repair services, and support in identifying appropriate spare parts for your hydraulic systems. In the event that your Danfoss RE orbital motor develops problems such as failure of torque generation or leakage of oil, our engineers will be able to inspect the machine and recommend how to go about repairs.
