وصف تفصيلي

The A2FM is a fixed displacement motor with an axial piston and bent axis design, specially developed to be suitable for hydrostatic drives in both open and closed circuits. Its bent axis structure ensures efficient power transmission, minimizes internal mechanical wear, and maintains stable performance in different circuit systems, making it adaptable to various hydraulic drive scenarios. This motor is widely used in both mobile and industrial applications, including construction machinery, agricultural equipment, and industrial hydraulic stations, capable of withstanding the harsh working environments of mobile equipment and meeting the stable operation requirements of industrial systems. The output speed of the A2FM motor is determined by the flow capacity of the matched pump and its own displacement—higher pump flow or smaller motor displacement will result in higher output speed, enabling flexible adjustment to meet different operational speed needs. Its torque increases with the pressure difference between the high and low pressure sides, and also rises with increasing displacement, ensuring it can provide sufficient power to drive heavy loads stably. Additionally, the motor adopts one-piece pistons with piston rings, which enhances sealing performance, reduces internal oil leakage, improves volumetric efficiency, and effectively extends the motor’s service life and operational reliability.
