The Rexroth A2FE hydraulic motor is a high - performance device designed to convert hydraulic energy into mechanical rotational energy. It is widely used in various heavy - duty and high - precision applications such as construction machinery, mining equipment, and industrial automation systems.
2. Construction and Design
Housing: The motor is housed in a robust casing, usually made of high - strength materials such as cast iron or steel alloys. The housing provides mechanical protection to the internal components and is designed to withstand high pressures and external forces. It also serves as a support structure for the shaft and other moving parts.
Internal Components: The A2FE hydraulic motor contains precision - machined internal components. The pistons, cylinder block, and valve plate are carefully designed and manufactured to ensure smooth and efficient operation. The pistons move within the cylinders of the cylinder block, and the valve plate controls the flow of hydraulic fluid to and from the cylinders, enabling the rotational motion of the motor.
3. Performance Specifications
Displacement:
The displacement of the A2FE hydraulic motor is a crucial parameter. It is measured in cubic centimeters per revolution (cc/rev). Displacement values vary depending on the specific model. For example, different models can have displacements ranging from 50 cc/rev to 1000 cc/rev. The displacement directly affects the torque output of the motor. A larger displacement generally means a higher torque output for a given hydraulic pressure.
Torque Output:
The torque output of the A2FE motor is a function of its displacement and the hydraulic pressure. The formula is used to calculate torque, where is the torque, is the hydraulic pressure, is the displacement, and is the mechanical efficiency. These motors can produce significant torque, ranging from a few hundred Newton - meters to several thousand Newton - meters. This high - torque capacity makes them suitable for applications that require a large amount of force to drive heavy loads or machinery.
Speed Range:
The A2FE series motors have a specific speed range. The minimum speed can be as low as a few revolutions per minute (rpm), depending on the hydraulic system and load conditions. The maximum speed can reach up to several thousand rpm. For instance, in some high - speed applications, the motor can operate at speeds around 4000 - 5000 rpm. The wide speed range allows for flexibility in different applications, from slow - moving heavy machinery to high - speed rotational equipment.
