Product Overview

 

Danfoss' OMR series is a type of axial-flow cycloidal hydraulic motor, known for its compact structure, good low-speed stability, and high torque output. The model OMR80 (product code 151-6471) introduced on this page is a classic product in this series, specially designed for medium-load applications that require reliable and efficient power transmission.

 

Core Features and Advantages

 

Danfoss OMR series motors integrate multiple advanced designs to ensure excellent performance even under harsh working conditions.

  • Efficient and stable power output: Adopting an optimized Gerotor design, it has a low starting pressure, enabling smooth operation and stable working torque throughout the entire speed range. It features high power per unit weight, generating greater torque among motors of the same volume, thus meeting high-intensity load requirements.
  • Robustness, reliability, and long service life: The motor incorporates a reliable linkage shaft design and a precision oil distribution system. The oil distribution mechanism has an automatic compensation function after wear, ensuring high volumetric efficiency and service life. The bearings have high radial and axial load-carrying capacities, capable of withstanding harsh working conditions.
  • Strong environmental adaptability: The advanced shaft seal design provides high back pressure resistance. The motor is suitable for various hydraulic media (such as mineral oil, biodegradable oil, etc.) and can be flexibly used in both open-loop and closed-loop hydraulic systems. Some models offer optional anti-corrosion components to cope with harsh environments.
  • Flexible installation and integration: The product has a compact structure and a robust design. It provides various flange, output shaft, and oil port connection forms, facilitating integration into various equipment. The motor allows for series or parallel operation (when connected in series, an external oil drain port is required), offering flexibility in system design.

 

Typical application fields

 

Thanks to its excellent low-speed and high-torque characteristics, the Danfoss OMR80 hydraulic motor is widely used in various mobile machinery and industrial fields:

  • Agricultural machinery: Used for the travel drive or rotation of working components in combine harvesters, seeders, and fertilizer applicators.
  • Engineering and construction machinery: Used to drive the working devices of small excavators, skid steer loaders, road rollers, and concrete mixing equipment.
  • Special vehicles and forestry machinery: Used in the hoisting or rotating mechanisms of road sweepers, forklifts, aerial work platforms, and wood harvesters.
  • Industrial equipment: Used in ship deck machinery, mining equipment, and various production lines that require low-speed and heavy-duty rotation.
