The A2FM is a fixed bent axial piston hydraulic motor with axial tapered piston rotary group in bent-axis design for hydrostatic drives in open circuits. Flow is proportional to drive speed and displacement. For axial piston units with bent-axis design, the pistons are arranged diagonally with respect to the drive shaft.
In an open circuit, the hydraulic fluid flows from the reservoir to the hydraulic pump from where it is fed via a directional valve to the consumer, e.g. hydraulic motor. From the consumer, the hydraulic fluid flows back to the reservoir via the directional valve.
This motor is available in sizes: 10 | 12 | 16 | 23 | 28 | 32 | 45 | 56 | 63 | 80 | 90 | 107 | 125 | 160 | 180 | 250.
