Danfoss H1B Series Motor | H1B250, H1B110 | Bent Axis Variable Piston Motor

Danfoss H1B Series High-Pressure Bent Axis Variable Motor

Product Overview: The Danfoss H1B series is a premier bent axis variable displacement motor engineered for sophisticated closed-circuit hydrostatic transmissions. Spanning displacements from 110cc (H1B110) to the massive 250cc (H1B250), this series is designed to deliver high torque and an exceptionally wide speed range for heavy-duty applications. Featured models such as the 83091563 (H1B250) and H1B110AALH… integrate advanced electro-proportional control modules, maintaining superior mechanical efficiency at working pressures up to 450 Bar. The bent axis architecture provides lower mechanical friction and a wider displacement ratio compared to swashplate motors, making it the ideal choice for rotary drilling rig power heads, large cranes, and harvester travel drives.

Key Technical Advantages:

• Superior Displacement Ratio & Speed Range: H1B motors feature a high maximum-to-minimum displacement ratio (including 0° capability), enabling machinery to transition smoothly from maximum climbing torque to high-speed transport without gear shifting.

• Ultra-High Pressure Reliability: Rated for continuous operation at 450 Bar (6525 PSI) with peak capabilities reaching 480 Bar, ensuring structural integrity under extreme shock loads.

• Intelligent Control Integration:

  • PBDNLN / PBVNEN Control Specs: Equipped with precision electro-proportional regulators and pressure compensators for agile and smooth system response.

  • NNNNP 050 / 074N22: Represents factory-precise configurations for control slopes, minimum displacement limits, and speed sensor interfaces.

• High-Efficiency Bent Axis Design: Optimized rotating groups significantly reduce breakaway torque and improve stable torque delivery at low speeds, leading to enhanced overall fuel efficiency.

• 100% OEM-Standard Compatibility (Smart Code): Complex long-form configuration codes ensure that flanges, shafts, seals, and control response times perfectly match original OEM equipment specifications.
