The Motor Orbital OMP is a lightweight cycloidal hydraulic motor. With its comprehensive range of performance parameters and compact design, it is well-suited for light- to medium-duty applications in small- and medium-sized equipment, making it the mainstream choice for use in agricultural machinery, light industrial machinery, and small-scale sanitation equipment, as well as for replacing older components. HANJIU has developed the Motor Orbital OMP in multiple specifications, with displacements ranging from 36 cc to 400 cc. Different displacement models offer varying torque and speed ratings, allowing users to select the appropriate model based on their load requirements.
The Motor Orbital OMP features a clear and stable performance parameter system. This series can withstand continuous operating pressures of up to 140 bar and peak pressures of up to 225 bar, enabling it to handle short-term shock loads. The speed range is 5–775 rpm; smaller-displacement models support higher speeds, while larger-displacement models emphasize low-speed, high-torque performance. Starting torque can reach 80%–90% of the rated continuous torque, ensuring excellent start-up response and smooth, vibration-free operation at low speeds. The torque output range is extensive, with continuous torque ranging from 55 to 435 N·m, and power delivery is linear and smooth. The motors maintain high volumetric efficiency, resulting in low energy loss during prolonged operation and minimizing issues such as power decay and excessive temperature rise.
Robust structural parameters give the Motor Orbital OMP its compact size and high load-carrying capacity. The product features a compact cycloidal rotor pair design, resulting in a lightweight unit that requires minimal installation space, perfectly addressing the challenge of limited installation space in many small devices. Equipped with a variety of standard flanges, output shafts, and oil port specifications, it offers options for flat-keyed and splined shafts. The oil ports are compatible with G1/2 and M-series threads, while the flanges support standard configurations such as two-hole diamond and four-hole diamond patterns. Thanks to the high versatility of its mounting interfaces, most legacy motors can be replaced directly in situ without modifying the frame or piping. The housing is made of cast iron and features a composite sealing assembly that resists dust and withstands muddy water, effectively reducing the risk of oil leaks and internal leakage in environments with high levels of contaminants, such as fields and construction sites.
Thanks to this balanced set of specifications, the Motor Orbital OMP is suitable for a wide range of applications. Small-displacement models feature high rotational speeds and a compact, lightweight design, making them suitable for small conveying mechanisms, brush drives, and auxiliary equipment for light agricultural machinery. Medium- and large-displacement models deliver ample low-speed torque and can be used in small winches, seeding equipment, straw shredders, and light industrial rotary mechanisms. The motors support forward and reverse rotation and can be connected in series or parallel to hydraulic circuits, adapting to a wide variety of equipment hydraulic system designs.
All motor orbital omp units manufactured by HANJIU are produced in strict accordance with standard specifications. Before shipment, each motor undergoes pressure, torque, and seal integrity tests, as well as high- and low-speed operation tests, to eliminate any deviations in specifications and ensure consistent performance during mass production. The parts are highly interchangeable, simplifying future repairs and keeping maintenance costs under control.
For equipment manufacturers and service providers, the Motor Orbital OMP series offers a wide range of specifications that balance installation dimensions, power output, and durability, delivering stable and reliable hydraulic power even in confined spaces. HANJIU can quickly match models based on equipment load, rotational speed, and installation space, providing comprehensive selection support and cost-effective, compact motor solutions for a wide range of small- and medium-sized hydraulic equipment.
