Applications:

1. In excavator applications, the A2FM motor delivers powerful hydraulic performance essential for large-scale earthmoving tasks. Integrated with a hydraulic motor, it provides rapid dynamic response and precise control, ensuring stable output during frequent start-stop operations. Its innovative bent‐axis design and compact build optimize fluid flow and minimize energy losses, resulting in improved efficiency and enhanced safety. This robust system meets the demands of heavy excavation work, significantly boosting operational productivity and reliability, ensuring optimal overall performance in every critical operation.

2. In excavator hydraulic systems, the A2FM motor is a key component that enhances digging efficiency with its superior dynamic response and high energy efficiency. Paired with a piston motor, it achieves precise regulation of flow and pressure, reducing operational risks and energy consumption. Its advanced bent‐axis design and minimized leakage contribute to stable performance even under continuous high loads. This integration ensures improved reliability, extended equipment lifespan, and consistent productivity during challenging excavation tasks, delivering consistently unmatched performance every time.

3. A2FM’s maximum torque output (3000 Nm) ensures aggregate mixing uniformity under low-speed heavy loads, with speed fluctuation rate <2%. Shock-resistant bearings withstand periodic load impacts during concrete curing. Closed-loop charge motors maintain oil cleanliness at ISO 4406 20/18, extending oil change intervals to 2000 hours.

Competitive Advantage:

1. The A2FM motor boasts excellent starting characteristics that deliver rapid initial torque and swift acceleration, and when combined with a piston motor, it facilitates immediate power delivery and smooth system engagement, ensuring efficient operation and quick recovery, which is critical for applications requiring fast and reliable startup performance, remarkably effective.

2. The A2FM motor is engineered with a wide range of finely graduated sizes, allowing for versatile adaptation to various drive cases, and when integrated with an axial piston motor, it offers customizable displacement and flow control, ensuring optimal performance and seamless integration into both mobile and stationary hydraulic systems, remarkably.

3. Achieving 3.2kW/kg power density with aluminum alloy housing reduces robotic joint drive unit weight by 18% while meeting EN 15000 safety standards, enhancing agile material handling performance.

The Analysis For Rexroth A2FM Fixed Displacemen Piston Motor Common Breakdown:

1. Cavitation, resulting from low inlet pressure or excessively high fluid velocity, may occur in the A2FM motor, causing vapor bubble collapse that damages internal components. This fault decreases efficiency and generates noise. Detailed evaluation of fluid parameters and pressure, including an inspection of the axial piston motor, is recommended to prevent further damage.

2. Misalignment during installation or operation can lead to increased wear on A2FM motor components and abnormal vibration, affecting fluid circulation and pressure transmission. Realigning the equipment and verifying all connections is critical, along with checking the hydraulic motor’s installation angle to ensure proper alignment and optimal performance.

3. Carbonized Seals Induce External Leakage‌: FKM seals carbonize at >110℃ oil temperature, causing >200mL/h leakage. Replace with high-temp FKM seals and add ≥15kW oil cooler in return line.
