Rexroth A2FE Series Plug-in Motor FAQ

1. Key Features and Characteristics

The Rexroth A2FE series is a line of fixed displacement axial piston motors with a bent-axis design. They are known for their high performance in open and closed circuit hydrostatic drive systems. The main features include:

• High Power Density and Efficiency: They offer high power in a compact size, with high total efficiency leading to energy savings.

• Space-Saving Design: A central recessed mounting flange allows for direct integration into mechanical gearboxes, making them ideal for applications with strict space constraints.

• High Pressure Rating: The motors are built for high-pressure operation, with nominal pressures of up to 400 bar (for sizes 28-180) and peak pressures of up to 450 bar.

• Ready-to-Install: These units are supplied as complete, pre-assembled, and tested modules, requiring only to be "plugged" into the gearbox, which reduces installation time and complexity.

• Excellent Performance: They provide high torque output and smooth operation with low noise and vibration levels.

2. Common/Standard Models

The A2FE series includes a wide range of models with different displacements to meet various power and speed requirements. Common models mentioned in the product listings include:

• A2FE28 / A2FE32 / A2FE45

• A2FE56 / A2FE63 / A2FE80

• A2FE90 / A2FE107 / A2FE125

• A2FE160 / A2FE180 / A2FE250 / A2FE355

3. Application and Usage Notes

A2FE motors are versatile and used in a wide array of mobile and industrial machinery, such as:

• Construction machinery (e.g., excavators, mixers)

• Agricultural equipment

• Material handling and conveyor systems

• Metallurgical, mining, and marine equipment

Important usage considerations:

• Steering Direction: The standard rotation is clockwise (viewed from the shaft end). Counter-clockwise rotation must be specified when ordering.

• Initial Startup: Before the first start, the motor casing must be filled with clean hydraulic fluid through the drain port.

• Alignment: Ensure proper concentricity between the motor and the driven unit to avoid noise and reduced efficiency.

• Working Fluid: Use recommended hydraulic oils (e.g., ISO VG 46 or 68) and maintain fluid cleanliness to ensure long service life.
