Applications:
Competitive Advantage:
1. The A2FM motor is fully compatible with modern digital control systems, allowing for precise monitoring and remote adjustments, and when combined with a piston motor, it facilitates automated tuning and real‐time performance tracking, making it an ideal solution for smart industrial systems that demand advanced control capabilities, ensuring unparalleled automation.
2. The A2FM motor incorporates advanced safety features that protect both the equipment and operators, and when used with a hydraulic motor, it ensures secure pressure regulation and rapid shutdown in emergency situations, thereby reducing risk and safeguarding industrial processes through reliable, high‐performance hydraulic control, guaranteeing utmost operational safety always consistently.
3. Hard-chrome plated pistons withstand 1,600℃ radiant heat in slab casting. 0.1r/min precision via closed-loop valves eliminates oscillation marks, achieving 8,000h MTBF.
The Analysis For Rexroth A2FM Fixed Displacemen Piston Motor Common Breakdown:
1. Prolonged high-load operation may cause abnormal wear of internal components in the A2FM motor—especially pistons, seals, and bearings—leading to overall performance degradation and increased failure risk. Regular maintenance, enhanced lubrication, and thorough inspection of the piston motor assembly are critical to prevent excessive wear and ensure long-term reliability.
2. Over time, cumulative factors such as oil contamination, component wear, seal failure, and inadequate maintenance can gradually degrade the overall performance of the A2FM motor, resulting in reduced efficiency and unstable output. A comprehensive evaluation of the entire hydraulic system, including the hydraulic motor, is essential to optimize design and restore reliable operation.
3. Housing Resonance Causes Bolt Fracture: 200Hz pressure pulsation resonance shears M12 bolts in 300h. Install rubber-metal dampers to shift resonance above 250Hz.
