Rexroth A2FM Axial Piston Fixed Motor Series 61 is designed for mobile and stationary applications providing powerful and dependable performance. These motors comes in fixed bent-axis design, which allows to function well in both open and closed circuit hydrostatic drives. They can be easily installed into limited space situations, because they are available in very compact design. These motors are available in multiple sizes ranging from 10 to 180 and delivers high power density as per the requirement.
These motors operate at a maximum pressure of 450 bar and a nominal pressure of up to 400 bar, providing excellent performance under challenging conditions. Rexroth A2FM motor is perfect for energy-conscious applications because it has a high total efficiency and good starting efficiency. 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 A2FM Axial Piston Fixed Motor Series 61 is finely graduated sizes permit far-reaching adaptation to the drive concerned. These motors comes with one-piece tapered piston with piston rings for sealing. A2FM motor features a long service life, sturdy construction, low noise level and higher performance, which make them ideal in most demanding applications. Additionally, they are available with optional features such as counterbalance and pressure relief valves.
