Danfoss 90M Series High-Pressure Variable Displacement Piston Motors

Product Overview: The Danfoss Series 90 motors are the technological cornerstone for high-performance closed-circuit drive systems worldwide. As an advanced variable displacement axial piston motor, this series is engineered to meet the extreme power demands of heavy-duty mobile machinery and industrial drives. Featured models like the 90M055 NC0N7N0S1W00NNN0000A3 (55cc) and 90M100 NC0N8N0C7W00NNN0000G0 (100cc) deliver exceptional speed and torque output. With a compact swashplate design and peak pressure ratings up to 480 Bar, these motors are widely utilized in pavers, rollers, harvesters, and heavy-duty crane drive systems.

Key Technical Advantages:

• Extreme Power Density: Delivers massive power output within a minimal footprint, optimizing the layout of modern machine compartments.

• Precision Modulation: Supports diverse control logics (NC0N), allowing real-time displacement adjustment for smooth acceleration and deceleration.

• Ultra-High Pressure Durability: Rated for continuous operation at 420 Bar (6000 PSI), specifically optimized to handle frequent shock loads and rigorous duty cycles.

• High-Speed Operational Efficiency: The optimized valve plate design not only suppresses noise but also permits higher RPMs while maintaining superior volumetric efficiency.

• Flexible Integration Options: Features SAE standard mounting flanges and splines (such as C7 and S1 options), ensuring seamless compatibility with various gearboxes and drive shafts.
