Key Technical Advantages

Application Areas

• Fishing Vessel Trawling Winches: Constant torque characteristic and wide speed range enable precise winch speed control; high starting torque ensures reliable loaded startup
• Marine Anchor Windlasses/Capstans: High starting torque efficiency enables smooth loaded starting; extremely low torque ripple at low-speed high-torque conditions
• Construction Equipment Swing Drives: Upper-structure swing for excavators and cranes — low-speed smoothness and loaded starting capability are critical requirements
• Injection Molding Machine Screw Drives: Constant torque and wide speed range enable precise screw plasticizing speed control
• Winch/Hoist Drives: High starting torque efficiency enables smooth loaded starting under full load conditions
• Machine Tool Spindle/Feed Drives: Precision machining enabled by wide speed range and low torque ripple
• Metallurgical Equipment: Continuous casting roller table drives, rolling mill auxiliary transmissions — heavy-duty continuous operation
• Marine Deck Machinery: Capstans and cranes requiring high starting torque and reliable stall protection

Expert Maintenance Tips

• Fluid Cleanliness Control: Maintain hydraulic oil cleanliness at ISO 4406 17/14/11 or better. The motor’s internal clearances are precision-machined; particulate contamination accelerates wear on the cam ring inner profile and vane tips, causing volumetric efficiency loss and increased internal leakage. Install a 10 μm absolute filter on the return line.
• Viscosity & Temperature Management: Recommended fluid: ISO VG 32–68 anti-wear hydraulic oil. Keep continuous oil temperature below 60°C. Start-up viscosity should be within 20–400 cSt. For cold starts, run the motor at low pressure and low speed for 5–10 minutes to warm the fluid before gradually loading to rated conditions above 20°C oil temperature.
• Case Drain Line Requirements: The M-series motor is equipped with an external drain port. If an external case drain line is used, it must be piped independently back to the reservoir. A preset throttle should be installed in the drain line to maintain approximately 3.5 bar (50 psi) case pressure, ensuring the motor remains filled with oil at all times. Benefits of case draining include: flushing the motor housing for contamination control, cooling the motor through discharged oil, and extending seal life by maintaining low case pressure. Never combine the drain line directly with the return line.
• Shaft Alignment: Use a flexible coupling between the motor output shaft and the driven load. Concentricity deviation must be controlled within φ0.1 mm to prevent bearing damage from bending moments or radial loads. Tighten flange mounting bolts in a diagonal pattern to ensure reliable face sealing.
• Rotation Direction Verification: While the M-series is bi-rotational, specific suffix configurations must be verified (114 suffix = 2,500 psi counter-clockwise / 2,250 psi clockwise; 124 suffix = bi-directional at 2,500 psi). Reversing rotation is achieved simply by reversing flow through the motor ports. Always confirm rotation direction matches system requirements before commissioning — viewed from the shaft end.
• Stall Protection: The M-series motor can be stalled under load without damage when protected by a relief valve, but stall duration should not exceed 6 seconds (intermittent duty cycle ≤10% of total operating time). Prolonged stalling causes rapid fluid temperature rise and seal damage. A relief valve is mandatory for system protection.
• Port Orientation Adjustment: The motor end cover can be assembled in different positions relative to the body. To change port orientation, simply remove the 4 end cover bolts and rotate the cover to the desired position, providing maximum piping flexibility.
• Cartridge Replacement Interval: Inspect vane wear and cam ring profile condition every 5,000 operating hours. Replace the cartridge assembly when volumetric efficiency drops by more than 15% or starting torque is noticeably reduced. The modular design enables field cartridge replacement in approximately 10 minutes without removing the motor from the equipment.
