MS05 Series Hydraulic Motor: Technical Overview & Applications
TheMS05 Series Hydraulic Motoris a compact, high-performance hydraulic motor designed for applications requiringmoderate torque, precise control, and efficient power transmissionin industrial machinery, mobile equipment, and specialized systems. Below is a structured breakdown of its key features, technical specifications, applications, and competitive advantages.
------
1. Key Features of the MS05 Series
The MS05 series balancespower density, efficiency, and reliabilitythrough the following design attributes:
A. Displacement & Power Output
• Displacement Range: Typically50–100 cc/rev(customizable in some models).
• Torque Capability:
• At200 bar (2900 psi)and 50 cc/rev:~160 Nm (118 lb-ft).
• At250 bar (3625 psi)and 100 cc/rev:~400 Nm (295 lb-ft).
• Speed Range:50–1500 RPM(depending on displacement and system flow).
B. Efficiency & Control
• Volumetric Efficiency:≥90%(reduced internal leakage via optimized valve plate design).
• Mechanical Efficiency:≥92%(low-friction bearings and precision gearing).
• Bidirectional Operation: Smooth torque output in both clockwise (CW) and counterclockwise (CCW) directions.
C. Construction & Durability
• Shaft Design: High-strength alloy steel withkeyway or splined optionsfor torque transmission.
• Sealing Technology:
• Double-acting lip sealsfor high-pressure resistance.
• Optional dust coversfor harsh environments (e.g., mining, construction).
• Mounting Flexibility:
• Flange mount,foot mount, orface mountconfigurations.
• SAE/ISO porting standardsfor easy system integration.
D. Operating Conditions
• Pressure Limits:
• Continuous: Up to250 bar (3625 psi).
• Peak: Up to280 bar (4060 psi)(short-term).
• Temperature Range:-20°C to +80°C(-4°F to 176°F) with standard seals (extended ranges possible with specialized materials).
• Viscosity Tolerance: Works with hydraulic fluids in the10–400 cStrange.

3. Applications of the MS05 Series
The MS05 motor excels in applications requiringmoderate power, compact size, and precise control, including:
【表格】
Industry Typical Applications
Agriculture Feed mixers, conveyor drives, hydraulic augers
Construction Mini-excavator swing drives, trencher rollers, compact loader attachments
Material Handling Pallet wrappers, tilt tables, lift truck steering systems
Forestry Log splitters, tree shears, harvester feed systems
Marine Anchor windlasses, deck winches, small thrusters
Example Use Case:
• In acompact trencher, the MS05 motor drives the digging chain at100–300 RPM, providing200–300 Nm torqueto cut through soil. Itscompact sizefits within the machine’s narrow frame, while itsbidirectional capabilityallows reverse operation to clear jams.

4. Advantages Over Competitors
The MS05 series offers distinct benefits compared to alternative motor designs:
【表格】
Factor MS05 Advantage
Power-to-Weight Ratio 30–50% lighter than equivalent-torque gear motors, improving machine maneuverability.
Efficiency 5–10% higher efficiency than vane motors at mid-range pressures, reducing heat generation.
Customization Displacement, porting, and shaft options tailor the motor to specific applications.
Reliability Fewer moving parts than piston motors, lowering maintenance costs in continuous-duty use.
------
5. Limitations & Considerations
• Low-Speed Efficiency: Below50 RPM, efficiency may drop due to fluid friction; use alow-speed, high-torque (LSHT) variantif needed.
• Peak Pressure Limits: Not suitable for300+ barapplications (considerMS18 seriesfor higher pressure).
• Noise: May produce75–85 dB(A)under load; add acoustic shielding for noise-sensitive environments.
------
6. Selection Criteria
To choose the right MS05 variant, evaluate:
1. Torque & Speed Requirements: Match displacement to load demands.
2. Mounting Space: Confirm compatibility with the machine’s layout (e.g., flange vs. foot mount).
3. Environmental Factors:
• Usehigh-temperature sealsfor >80°C operation.
• Opt forstainless steel shaftsin corrosive environments.
4. System Integration: Ensure ports, flows, and pressures align with existing hydraulic circuits
