Applications for Gerotor Motors
Gerotor motors are commonly used in hydraulic systems where smooth, consistent rotary motion is required under load. These motors are ideal for powering augers, conveyor drives, fan systems, and lift mechanisms across a range of industries. They are frequently found in agriculture, construction, and mobile machinery and equipment, where space-saving, low-speed, high-torque power is essential for performance and efficiency. To explore more, view our full list of industries we serve.

Gerotor Motor FAQs
What Is the Difference Between a Gerotor and a Geroler Motor?
Gerotor motors use a rotor and an internally geared stator to generate smooth, low-speed hydraulic rotation. Geroler motors add rollers between the rotor and stator, improving wear resistance and low-speed efficiency. Geroler motors are better suited for applications requiring higher torque consistency or longer duty cycles. For roller-based models, see our Geroler Motors.
Can Gerotor Motors Be Mounted in Any Orientation?
Yes, most gerotor motors can be mounted vertically or horizontally, as long as the unit is properly supported and hydraulic lines are correctly routed. Always follow manufacturer's installation guidelines to ensure optimal seal performance and prevent shaft misalignment.
How Do I Know Which Displacement Size I Need?
Displacement size (measured in cu in/rev) determines the flow rate and torque output of the motor. Smaller displacements are ideal for faster speeds with less torque, while larger displacements deliver higher torque at slower speeds. Choosing the right size depends on your system's hydraulic flow, load requirements, and speed targets. Our team can help you size the correct motor for your application.
