The Analysis For Rexroth A6VE Piston Motor Common Breakdown:
1. External debris contamination can infiltrate the A6VE motor,
leading to blocked fluid channels and erratic performance;
particularly when an axial piston pump draws in extra particles,
the fault is aggravated, so regular system cleaning and
environmental protection measures are required to guarantee stable
efficiency and long-term reliable performance.
2. Abnormal vibrations may occur in the Rexroth A6VE piston motor
when the rotor or bearings experience wear or damage. Excessive
vibration not only disrupts smooth operation but also increases
noise levels and can trigger premature failure of other components.
Regular checks for bearing and rotor balance and timely replacement
of worn parts are crucial steps to reduce vibration risks and
maintain the overall stability of this hydraulic motor.
3. Unintended Rotation Reversal: Reverse rotation may indicate
shuttle valve jamming or reversed electrical polarity. Inspect
shuttle valve mobility and validate wiring per ISO 1219.
