Product Description

YLM, NAM, IAM & NHM Series External Plunger Low Speed High Torque Motors

Product Overview: The YLM, NAM, IAM, and NHM Series represent the benchmark for industrial Low Speed High Torque (LSHT) hydraulic motors. Featuring the classic External Plunger (Five-star) design, these motors are engineered for the most extreme heavy-duty operating conditions. This page highlights the full displacement range within the 11-frame size: 11-800, 11-900, 11-1000, 11-1100, 11-1200, 11-1300, and 11-1400. Renowned for their superior startup efficiency, ultra-low speed stability, and exceptional shock resistance, these motors are widely used in heavy-duty winches, marine windlasses, plastic injection molding machines, mining drills, and construction machinery.

Key Technical Advantages:

  • Extreme Torque Output: The unique external plunger and connecting rod architecture allows for massive, smooth torque delivery at ultra-low RPM, ideal for heavy-load startups.

  • Superior Shock Resistance: Robust cast-iron housings and reinforced internal components enable these motors to handle violent load fluctuations and intense pressure spikes.

  • Low-Speed Smoothness: Maintains consistent power delivery even at speeds below 1 RPM, ensuring precise operation without “creep.”

  • Modular Displacement Flexibility: The 11 Series offers displacements from 800cc to 1400cc, allowing for precise matching to specific machinery load requirements.

  • Target Applications: Industrial presses, conveyor belt drives, marine deck machinery, injection molding pre-plasticizing, and geological rig rotary tables.

Detailed Models & Parameters:

  • Core Series: YLM, NAM, IAM, NHM Series.

  • Model Keywords: 11-800, 11-900, 11-1000, 11-1100, 11-1200, 11-1300, 11-1400.

  • Technical Specs Decoding:

    • 11-800 / 11-1000: Balanced torque and speed response for medium-to-heavy machinery.

    • 11-1200 / 11-1400: Provides maximum startup traction for top-tier heavy-duty industrial drives.

  • Pressure Specs: Rated Operating Pressure up to 20-25 MPa, with peak capabilities reaching 31.5 MPa.
