Competitive Advantage:

1. A6VM107 variable piston motor supports stepless speed regulation in a wide range. It maintains stable high torque output at low speed and has strong load adaptability, meeting the frequent start-stop and variable-load operation requirements of light construction machinery.

2. Compact structure with high power density. It delivers powerful driving force within limited installation space and facilitates overall machine layout. Designed with precise internal friction pairs, it runs with low vibration, ideal for mobile equipment such as mini excavators and road rollers.

3. It can withstand alternating impact loads generated during operation with good fatigue resistance and longer service life. Original and replacement spare parts are readily available in the market, facilitating later maintenance and effectively reducing equipment downtime losses.

The Analysis For Rexroth A6VM Piston Motor Common Breakdown:

1. Insufficient motor output torque and weak power. It is mostly caused by worn valve plate and aging piston seals leading to excessive internal leakage. The motor cannot reach rated torque, the machine lacks power under load, and the speed drops significantly during climbing or heavy-duty work, failing to complete construction actions normally.

2. Abnormal noise and violent vibration during operation. The main causes are contaminated hydraulic oil, air entering the oil suction side or bearing wear. Impurities and cavitation continuously impact internal precision components. Noise and vibration will keep worsening, and the motor internal parts may get seized in serious cases.

3. Excessive temperature rise of motor housing. Excessive internal leakage, high oil return back pressure or stuck variable mechanism will lead to heat accumulation. High temperature accelerates seal aging and reduces oil viscosity, further aggravating wear and shortening the overall service life of the motor.
