Within the vast and intricate machinery of modern industry, power transmission is as vital as blood flow. When conventional motors fall short due to size, torque limitations, or environmental adaptability, a more compact and resilient power core emerges—the motor orbital hidraulico. Hanjiu Technology Co., Ltd. deeply understands this principle, dedicated to transforming the essence of this high-efficiency power unit into a reliable force driving steady progress across all industries. The hydraulic cycloidal motor, often referred to as a cycloidal rotor motor, is an internally meshed gear-type hydraulic motor featuring a special cycloidal profile. Its design philosophy is rooted in the ultimate pursuit of space and efficiency, centered on a simple planetary reduction principle: a smaller-toothed outer gear rotor rotates eccentrically within a larger-toothed inner gear stator. This seemingly straightforward relative motion creates a series of sealed, periodically changing cavities between their tooth profiles. The injection and discharge of high-pressure hydraulic fluid cause these cavities to sequentially expand and contract, converting the fluid's pressure energy into smooth, continuous rotational motion of the rotor and substantial torque at the output shaft.
This unique operating principle endows Hanjiu Technology's motor orbital hidraulico with a series of remarkable intrinsic qualities, setting it apart among numerous power solutions.
High Power Density and Compact Structure. Thanks to its ingenious internal planetary gear design, the cycloidal motor achieves significantly smaller dimensions than other hydraulic motor types while delivering equivalent output torque. This compact, lightweight, and space-efficient structure allows seamless integration into equipment layouts with limited space, greatly facilitating lightweight and modular machine design. It exemplifies the concept of “small size, big power.”
Exceptional low-speed high-torque performance. Motor speed is proportional to input flow, while torque directly correlates with operating pressure. Its inherent multiple-tooth-difference structure inherently provides a speed-reducing torque-increasing effect, enabling it to deliver smooth and powerful low-speed torque directly from the output shaft without requiring bulky additional reduction gearing. This characteristic makes it an ideal choice for various applications requiring direct drive or precise low-speed control, such as travel drives for construction machinery, rotating platforms, or direct propulsion of conveyor rollers.
Exceptional Starting and Operating Characteristics. With minimal rotational inertia, cycloidal motors start effortlessly under load and achieve mechanical efficiencies exceeding 85%. They support frequent forward-reverse switching without shutdown, delivering responsive operation. Simultaneously, their smooth operation and low noise levels ensure continuous equipment performance and a comfortable working environment.
Exceptional environmental adaptability and reliability. As a fully hydraulic drive unit, it inherently offers shock resistance, explosion-proof capabilities, and tolerance for harsh environments. Its simple, robust construction ensures stable operation in humid, dusty, or temperature-fluctuating conditions. Through precision manufacturing and stringent quality control, Hanjiu Technology further enhances product longevity and reliability, guaranteeing rock-solid performance even under severe challenges.
Hanjiu Technology's hydraulic cycloidal motors have become integral to the lifeblood of modern industry. In construction machinery, they serve as the reliable, silent drivers of excavator and loader travel systems. In agricultural equipment, they propel harvesters and seeders with precision across fields. On ship deck machinery, port cranes, and heavy oil drilling rigs, they deliver indispensable rotational power. Whether powering winches requiring constant tension, mixers demanding precise angular velocity, or indexing and flipping mechanisms on automated production lines, they uniquely transform the surging power of hydraulic systems into precise, controllable mechanical motion.
