Hydraulic motors are mechanical actuators that convert hydraulic pressure and flow into torque and angular displacement. They are essential components in various industrial, mobile, and marine applications, providing high power density and precise control. Unlike electric motors, hydraulic motors thrive in harsh environments, offering robust performance and reliability under extreme conditions. They are commonly used in construction equipment, agricultural machinery, material handling systems, and more, where high torque at low speeds is required.
Our hydraulic motors are available in multiple series, each tailored to specific applications. Below is a detailed table of key parameters for our standard models.
| Model Series | Displacement (cm³/rev) | Max Pressure (bar) | Speed Range (rpm) | Max Torque (Nm) | Efficiency (%) | Weight (kg) |
|---|---|---|---|---|---|---|
| HM-100 | 50 | 250 | 100-2000 | 120 | 92 | 15 |
| HM-200 | 100 | 300 | 80-1800 | 250 | 94 | 25 |
| HM-300 | 200 | 350 | 60-1600 | 500 | 95 | 40 |
| HM-400 | 400 | 400 | 50-1400 | 1000 | 96 | 65 |
| HM-500 | 800 | 450 | 40-1200 | 2000 | 97 | 100 |
Note: Displacement refers to the volume of fluid required to rotate the motor one revolution. Maximum pressure indicates the peak operating pressure, while speed range shows the minimum and maximum rotational speeds. Efficiency values are based on standard testing conditions with ISO VG 46 hydraulic fluid at 40°C. Weight includes standard mounting configurations.
What is the difference between a hydraulic motor and a hydraulic pump?
A hydraulic pump converts mechanical energy into hydraulic energy by generating flow, while a hydraulic motor converts hydraulic energy back into mechanical energy by producing torque and rotation. Pumps are typically driven by engines or electric motors, whereas motors drive external loads.
How do I select the right hydraulic motor for my application?
Consider factors such as required torque, speed range, operating pressure, displacement, and environmental conditions. Match the motor's specifications to your system's demands, and consult technical datasheets or our support team for tailored recommendations based on load, cycle time, and fluid compatibility.
What maintenance is required for hydraulic motors?
Regular maintenance includes checking for leaks, monitoring fluid cleanliness, inspecting seals and bearings, and ensuring proper lubrication. Follow the manufacturer's guidelines for service intervals, typically involving oil changes every 1000 hours and component inspections annually or based on operating hours.
Can hydraulic motors be used in high-temperature environments?
Yes, our hydraulic motors are designed to operate in temperatures ranging from -40°C to 100°C, with optional upgrades for extreme conditions. Use high-temperature seals and compatible hydraulic fluids to prevent degradation and ensure optimal performance.
What causes hydraulic motor failure, and how can it be prevented?
Common causes include contamination, overheating, overpressure, and misalignment. Prevent failure by using clean fluid, maintaining proper filtration, avoiding exceedance of pressure ratings, ensuring correct installation, and conducting routine inspections to catch issues early.
Are hydraulic motors reversible?
Most hydraulic motors are bidirectional, meaning they can rotate in both directions based on the flow direction of the hydraulic fluid. Check the model specifications for details on reversible operation and any limitations.
How efficient are hydraulic motors compared to electric motors?
Hydraulic motors excel in high-torque, low-speed applications and often have higher power density, but electric motors can be more efficient in certain scenarios, especially at constant speeds. Efficiency depends on the application; hydraulic systems are preferred for their robustness and flexibility in variable load conditions.
What types of hydraulic fluids are compatible with your motors?
Our motors are compatible with standard mineral-based hydraulic oils, synthetic fluids, and biodegradable options. Use fluids with ISO VG 32 to 68 viscosity ranges and ensure they meet anti-wear and oxidation stability standards, as specified in the product manual.
Can I customize a hydraulic motor for specific needs?
Yes, we offer customization options including special shaft configurations, mounting flanges, port sizes, and coatings for corrosion resistance. Provide your requirements, and our engineering team will develop a solution tailored to your application.
What is the typical lifespan of a hydraulic motor?
With proper maintenance, our hydraulic motors can last over 10,000 hours of operation. Lifespan varies based on usage intensity, environmental conditions, and adherence to maintenance schedules. High-stress applications may require more frequent servicing or component replacements.
