Orbital Motor OMR 80


The OMR 80 is an orbital motor, most likely used in various mobile and industrial applications requiring precise control of speed and torque. Here's a breakdown of what we know about OMR 80 motors




OMR 80 likely refers to a specific model of orbital motor manufactured by several companies, 

Orbital motors use a gerotor design. This design involves

An inner, oval-shaped gear (rotor)

An outer gear with matching teeth (stator)

Hydraulic fluid flows through the motor, putting pressure on the rotor's teeth, causing it to rotate around the stator.

The specific shape of the rotor and stator creates a continuous pressurized pocket of fluid that pushes the rotor, generating torque.

By controlling the flow and pressure of the hydraulic fluid, the speed and direction of the OMR 80's shaft rotation can be precisely controlled.



OMR 80 motors, due to their ability to deliver high torque at low speeds and compact size, are suitable for various applications such as


Construction Equipment

Driving wheels (for locomotion) in mini excavators or skid steer loaders.

Swing drives (rotating the upper body of the machine) in mini excavators.

Powering attachments (like augers or trenchers) on skid steer loaders or compact tractors.

Tilting buckets or blades on compact machinery.

Agricultural Machinery

Powering wheels on zero-turn mowers or compact tractors.

Operating augers or drills for planting or soil sampling.

Driving conveyor belts for moving crops or materials.

Industrial Automation

Conveyor belt drives in assembly lines.

Material handling equipment like mixers or shakers.

Operating robotic arms or turntables in low-speed, high-torque applications.

Specifications (Examples)


Displacement OMR 80 motors likely have a displacement around 80 ccrev (cubic centimeters per revolution), indicating the volume of fluid delivered per revolution of the shaft. This is a typical estimate, and the exact displacement can vary depending on the manufacturer's model.

Pressure The maximum operating pressure may vary depending on the specific manufacturer's model, but it typically ranges from 140 to 225 bar (around 2000 to 3200 psi) for OMR motors in general.

Torque OMR 80 motors can generate high torque at low speeds, making them suitable for demanding applications.

Important Note


The specific features, applications, displacement, pressure rating, torque output, and recommended applications of the OMR 80 can vary depending on the manufacturer's model.

If you have a specific OMR 80 motor, it's crucial to refer to the manufacturer's specifications or datasheet for accurate information.

Finding More Information About Your OMR 80


Look for a part number The motor itself might have a part number that can help identify the manufacturer and specific model.

Consult the user manual or parts catalog for your equipment. It should specify the model and function of the OMR 80 motor.

Contact a hydraulics specialist HANJIU . They can provide detailed information based on the specific model and manufacturer.

I hope this comprehensive explanation clarifies the OMR 80 orbital motor and its applications. Feel free to ask if you have any further questions!
