Product Description
Danfoss MMF Series Fixed Axial Piston Hydraulic Motors
Product Overview: The Danfoss MMF Series comprises premium fixed displacement axial piston motors engineered for medium-power closed-circuit hydrostatic transmissions. Utilizing a time-tested swashplate design, the MMF series delivers exceptional output torque and power density within a remarkably compact footprint. This category features the primary sizes MMF035 and MMF044, including precision configurations: MMF035D AAGABNNN, MMF044DAF1ABNNN*, and MMF044DASGABNNR. These motors are the industry choice for compact rollers, harvester auxiliary drives, material handling machinery, and municipal service vehicles.
Key Technical Advantages:
Extreme Spatial Efficiency: Optimized swashplate architecture minimizes motor volume, facilitating easy integration into space-constrained wheel-end or chassis drive compartments.
High-Speed Stability: Precision-balanced rotating groups support smooth operation at high RPMs, ensuring high-efficiency drive response.
Rugged Durability: Specifically built for the frequent reversals and high-pressure spikes of closed-circuit systems, with reinforced internal components for extended service life.
Versatile Technical Spec Options:
DAF1AB / DASGAB: Relates to specific shaft spline standards, flange types, and porting configurations.
NNN / NNR: Corresponds to different sealing standards and case drain back-pressure tolerance.
Target Applications: Vibratory roller travel drives, rotary drill rig auxiliary motors, specialized agricultural tractors, and street sweeper drives.
