Rexroth A2FE Axial Piston Fixed Motor - Series 70 is a high performance and durable motor, specially designed for stationary and mobile applications. These motors are designed for hydrostatic drives in both open and closed circuits, comes with fixed displacement and bent-axis construction. They have compact size, that allows to be installed in limited space. Their high power density ensures smooth and reliable performance even in the most demanding circumstances.
Rexroth A2FE motor is renowned for their high power density, small dimensions, high total efficiency and good starting efficiency. They come in a wide range of sizes that can be easily integrated into a variety of mechanical gear systems. They are available in multiple series, A2FMN, A2FEN (sizes 28 to 107) with nominal pressure 300 bar and maximum pressure 350 bar. A2FMM, A2FEM (sizes 23 to 180) comes with nominal pressure 400 bar and maximum pressure 450 bar and A2FMH, A2FEH (sizes 45 to 125) are available with nominal pressure 450 bar and maximum pressure 500 bar.
The output speed depends on the flow of the pump and the displacement of the motor. Their output torque increases with the pressure differential between the high-pressure side and the low-pressure side. Rexroth A2FE can rotate at very high rates, guaranteeing smooth operation even in the most demanding conditions. These motors comes with long service life and superior resistance to torsional vibrations add to its durability and low maintenance requirements.
