Orbital Hydraulic Motor: A High-Efficiency, Reliable Hydraulic Power Solution

2026-05-06

The orbital hydraulic motor is a low-speed, high-torque hydraulic power component. With years of expertise in this field, HANJIU’s products have become the preferred drive components in industries such as manufacturing, agriculture, and construction machinery, thanks to their stable performance and high adaptability.

 

1. Compact Size and High Torque Density

The hydraulic orbital motor employs an internally meshing cycloidal gear structure, where the stator and rotor form a sealed working chamber. Hydraulic oil drives the rotor to rotate, converting hydraulic energy into mechanical energy. Its compact design occupies only 1/3 to 1/2 the volume of a piston motor of the same torque rating and weighs over 30% less, making it ideal for installation in equipment with limited space. This motor offers high torque density, with a rated pressure of up to 16 MPa and a maximum pressure approaching 20 MPa. It delivers a maximum output torque of 1,900 Nm and can stably produce high torque at low speeds without requiring an additional reduction mechanism, thereby simplifying the equipment’s transmission system.

 

2. Wide speed range and stable operation

The hydraulic orbital motor offers excellent speed control performance, with a speed range of 15–1,850 rpm. Stepless speed regulation is achieved by adjusting the hydraulic system flow, and the minimum stable speed reaches 15 rpm without any crawling phenomenon, making it suitable for a wide range of operating conditions. Featuring a face-type distribution design and a toothed stator-rotor assembly, the motor has low starting pressure and a starting torque of 80%–90% of the rated torque. It starts easily under load, and direction reversal is possible without stopping the machine, ensuring smooth and shock-free switching. HANJIU’s products feature an optimized flow distribution structure, with volumetric efficiency of no less than 90% and overall efficiency of no less than 85%. They operate with low energy consumption, significantly reducing equipment operating costs over the long term.

 

3. High Adaptability, Durability, and Ease of Maintenance

Industrial environments are complex, and the motor orbital hidraulico offers excellent environmental adaptability and durability. Core components are made of high-strength carburized steel that has undergone quenching treatment, resulting in high surface hardness and strong wear resistance; the sealing system uses high-quality materials capable of stable operation in environments ranging from -20°C to 80°C, and its contamination-resistant design blocks impurities in hydraulic oil, extending service life. With a simple structure and few components, this motor is easy to disassemble and repair, resulting in low maintenance costs. It achieves an average mean time between failures (MTBF) of over 8,000 hours, making it suitable for long-term operation in harsh environments such as mines, farmlands, and factory workshops—where conditions include high levels of dust, humidity, and oil contamination.
