Product details
2.5 2.5A Series Hydraulic Motor
I. Technical Specifications and Core Parameters
1. Model and Brand Compatibility
• Typical models, such as Hengnuo Hydraulic's4IKY2.5 2.5A series, support customized production with a rated voltage of 220V, suitable for industrial applications in mainland China.
• Displacement range: Total displacement can reach800mL/rev(calculated by multiplying the hydraulic motor displacement by the reduction ratio of the gearbox), with rated torque determined based on system pressure (16MPa or 20MPa), considering pressure loss and transmission efficiency.
2. Speed and Efficiency
• Speed Range: Supports low-speed (<500rpm) and high-speed (>500rpm) applications, depending on gearbox configuration (e.g., single-stage planetary gearbox).
• Transmission Efficiency: Affected by the mechanical efficiency of the hydraulic motor and the efficiency of the planetary gearbox, influencing output power.
3. Working Pressure and Hydraulic Oil Requirements
• Working Pressure: Allows a maximum back pressure of 10MPa, with case pressure ≤0.1MPa; back pressure must be specified for oil return.
• Hydraulic Oil: Recommended to use mineral-based hydraulic oil, operating at temperatures of 30°C~50°C, with a viscosity of 40~60 centistokes; special treatment required for low-temperature or high-temperature environments.
II. Application Scenarios and Industry Solutions
1. Industrial Automation
• CNC Machine Tools: Drives feed systems for micrometer-level machining accuracy.
• Robotic Joints: High-precision stepper motors (e.g., 20mm stepper motor with a volume of only Φ20×36mm) used in collaborative robot end-effectors, with an error margin ≤0.1°.
2. Construction Machinery
• Excavator Slewing Drives: Integrates hydraulic motors and gearboxes for 360° rotation, equipped with precise braking and anti-reversal functions.
• Crane Booms: Delivers low-speed, high-torque output for heavy-duty lifting requirements.
3. Transportation and Logistics
• AGV Vehicles: Drives wheel hubs with a climbing capability ≥8° and positioning accuracy ±10mm.
• Logistics Sorting Systems: Integrates 2.5A motor modules for a sorting efficiency of 6,000 pieces/hour and a 50% reduction in failure rates.
4. Consumer Electronics
• POS Printers: 2.5A motor drives printheads with a first-line output time ≤0.5 seconds and a lifespan of 500,000 cycles.
• Security Cameras: Pan-tilt motors support 360° rotation with positioning accuracy ±0.02° and noise levels <30dB in night vision mode.
5. Renewable Energy
• Wind Turbine Pitch Systems: Hydraulic gearboxes adjust blade angles to optimize energy capture under varying wind speeds.
III. Product Advantages and Technical Highlights
1. High Efficiency and Compact Design
• Power Density: The 20mm stepper motor, with a volume of only Φ20×36mm, achieves a power density of 0.5kW/kg, suitable for compact spaces.
• Drive Method: Dual H-bridge drive supports PWM speed control, forward/reverse rotation, and adaptive blanking time.
2. Reliability Design
• Protection Features: Built-in overcurrent protection (OCP), thermal shutdown (TSD), and undervoltage lockout (UVLO), with a failure rate <0.1%.
• Lifespan Testing: Motor bearings have a lifespan of 20,000 hours (MTBF), adapting to a wide temperature range of -20°C to 70°C.
3. Modularity and Customization
• Shaft Size Customization: Supports various output forms such as D-type shafts and flange shafts to suit different load requirements.
• Accessory Expansion: Can integrate encoders, brakes, and gearboxes to form a complete drive unit.
4. Environmental Adaptability
• Protection Grade: Some models reach IP68, suitable for underwater or high-dust environments.
• Corrosion Resistance: Marine environments require corrosion-resistant materials (e.g., stainless steel).
IV. Selection Guide and Key Parameters
1. Load Matching
• Load Inertia Ratio: Recommended <10:1 to avoid step loss.
• Torque Calculation: Match motor output torque using the formulaPHydraulic Oil=Flow Rate×Pressure=Torque×Angular Velocity P_{\text{Hydraulic Oil}} = \text{Flow Rate} \times \text{Pressure} = \text{Torque} \times \text{Angular Velocity} PHydraulic Oil=Flow Rate×Pressure=Torque×Angular Velocity.
2. Temperature Control
• Continuous operating temperature rise ≤40K; adjust current based on cooling conditions.
3. Installation and Maintenance
• Drain Tube Positioning: Ensure the housing is filled with hydraulic oil during operation.
• Hydraulic Oil Replacement: Regularly replace hydraulic oil and filters to extend service life.
4. Special Requirements
• Overpower Usage: Contact the manufacturer for material and surface treatment enhancements to improve performance, albeit at increased cost.
