Applications:
Competitive Advantage:
1. The A2FM motor is designed for excellent environmental adaptability, performing reliably under extreme temperatures and varying conditions, and when paired with a piston motor, it maintains stable hydraulic performance despite external fluctuations, ensuring that industrial systems operate efficiently in both harsh and mild climates, delivering outstanding adaptability always for excellence.
2. Vector control with ＞85% energy regeneration enables 0-1,500m/min speed regulation for paper machines, reducing total consumption by 18%.
3. The hydraulic motor micro-pulse control with pulsation dampers achieves 0.001mm roll gap accuracy. ＜±0.2bar pressure fluctuation ensures I-grade steel flatness.
4. The piston motor equipped with planetary gear reducers enable 800kW power output for deep mine conveyors. Dual-motor synchronization error ＜0.5% with 20,000-hour bearing life under 350bar continuous pressure.
The Analysis For Rexroth A2FM Fixed Displacemen Piston Motor Common Breakdown:
1. Seal failure is a common issue in the A2FM motor, often caused by prolonged high-temperature operation, oil contamination, or mechanical wear, resulting in leakage and pressure loss. Compromised seals reduce energy conversion efficiency. Prompt replacement and inspection of the axial piston motor seals are recommended to restore performance.
2. Contaminated hydraulic oil can increase internal wear, damage seals, and raise flow resistance, adversely affecting the A2FM motor’s efficiency and output stability. Polluted oil accelerates component degradation and failure. Regular oil replacement, system cleaning, and maintenance of the piston motor are essential to ensure pure fluid quality and reliable performance.
3. 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.
