Cycloidal Motors in Stock
Cycloidal motors, also called orbital or gerotor/geroler motors, are low-speed high-torque hydraulic motors that convert hydraulic pressure and flow into smooth rotary motion through an internal cycloidal gear set. They deliver high torque at low speeds with a compact, robust design, making them ideal for direct-drive applications that require strong starting torque and reliable performance. Our inventory covers a wide range of single-speed and multi-speed cycloidal motors in various displacements and mounting styles, engineered for agriculture, construction, material handling, and other mobile equipment.
Hengyuhang combines strong manufacturing capacity with specialized engineering expertise to produce high-quality cycloidal motors. Manufactured to stringent international quality standards, our cycloidal motors deliver the reliability, efficiency, and long service life required to serve as direct, drop-in replacements for leading international brands. When standard equipment cannot meet specific technical demands, our facility designs and manufactures entirely custom cycloidal motor solutions — from rapid prototyping to full-scale production — engineered strictly to your operational parameters and application needs.
What Is a Cycloidal Motor?
A cycloidal motor is a hydraulic motor that converts hydraulic energy into mechanical torque and rotation using an internal cycloidal gear set (a rotor and stator pair). Pressurized fluid enters the motor and drives the rotor in an orbital motion around the stator, producing smooth, continuous rotation of the output shaft. Cycloidal motors are valued for their high torque at low speed, compact size, durability, and excellent resistance to contamination, making them a reliable choice for direct-drive and wheel-drive applications.
Types of Cycloidal Motors
Cycloidal motors are generally classified by their structure, speed stages, and output configuration.
Single-speed cycloidal motors are the most common type, delivering a fixed displacement and a direct one-to-one relationship between flow and speed. They are simple, economical, and robust.
Multi-speed cycloidal motors provide two or more selectable speed and torque ranges by redirecting fluid within the motor, allowing one motor to serve different working conditions.
Wheel-mount and flange-mount cycloidal motors are designed for direct integration into wheel hubs, compact track loaders, and other mobile equipment where space is limited.
Applications of Cycloidal Motors
Cycloidal motors drive low-speed high-torque rotary functions across a wide range of industries:
Agricultural machinery — harvesters, seeders, spreaders
Construction equipment — augers, compact track loaders, mini excavators
Sweepers and road maintenance machinery
Conveyors and feed systems
Winches and hoists
Turf care and groundskeeping equipment
Industrial and material handling equipment

FAQ of Cycloidal Motors
1. What is a cycloidal motor used for?
Cycloidal motors are used to drive low-speed high-torque rotary functions such as augers, harvesters, sweepers, winches, and wheel drives in agricultural, construction, and industrial equipment.
2. What is the difference between a cycloidal motor and a gear motor?
A cycloidal motor uses an internal cycloidal gear set to produce high torque at low speed, while a gear motor uses meshing gears. Cycloidal motors generally offer higher torque density and better low-speed stability, while gear motors are simpler and more economical.
3. What types of cycloidal motors are available?
Cycloidal motors are available in single-speed and multi-speed versions, with flange-mount and wheel-mount configurations.
4. Can your cycloidal motors replace other brands?
Yes. Our cycloidal motors are engineered as direct, dimensionally interchangeable replacements for PARKER, EATON, DANFOSS, and BREVINI models.
5. Do you offer custom or OEM cycloidal motors?
Yes. We offer OEM batch customization — you can provide the design, or we can design the motor to your specification, with optional private labeling.
6. What is the MOQ for OEM orders?
MOQ is flexible depending on the model and customization requirements. Contact us for a tailored quotation.
7. What is your lead time?
Lead time depends on quantity and customization. Standard models ship quickly; custom orders are confirmed at quotation.
