run in either open or closed circuits. This is not a light-duty motor. It is used in higher-pressure applications where output speed, torque, and control response all matter.
Its variable displacement is a major advantage. Instead of staying in one fixed operating state, the motor can cover a broader working range, and the series design allows adjustment down to zero. Options such as flushing, boost-pressure, and counterbalance arrangements also make it easier to use in tougher drive circuits.
Common applications include travel drives and winch drives. Size 250 in the current program is also used in gearbox-related drive packages. Overall, the AA6VM family fits both mobile and stationary hydrostatic systems that need compact, controlled rotary drive output.
Key Features & Benefits
Bent-axis construction gives the aa6vm motor a compact, heavy-duty drive layout with good torque behavior.
Variable displacement helps the same motor cover both higher-speed and higher-torque operating points.
Works in open and closed circuits, so system matching is more flexible.
Larger current series sizes run in the 350 / 400 bar class, which is already serious drive-duty territory.
The series is described as suitable for very high rotational speeds when matched correctly.
Different control options make it easier to match the motor to the machine instead of forcing the machine around one control style.
Optional flushing / boost-pressure valve helps with thermal and circuit-side housekeeping on harder jobs.
Optional counterbalance-valve arrangements are useful on applications where load control matters more than brochure language.

The displacement, pressure, speed, flow, and weight values above come from the technical-data pages for sizes 250 to 1000. The port sizes are taken from the size-specific dimension pages for 250, 355, 500, and 1000.
A few practical points worth checking before order: port plate style can be rear A/B, side-opposite A/B, or side-opposite plus rear A1/B1 depending on the port plate; shaft ends vary by version; and control-dependent ports like G, G2, X, X1/X2, X3, P, U are not the same on every build. That is why quoting only by "AA6VM" is never enough.

How It Works
Pressure oil comes in and pushes the rotary group into motion
AA6VM is a hydraulic motor, so the energy flow goes the opposite way from a pump. Hydraulic flow enters the motor, acts on the axial piston rotary group, and turns the output shaft. In basic terms, it converts hydrostatic energy into mechanical rotation.
The bent-axis layout and displacement setting decide how the motor behaves
Because it is a variable motor, displacement is not stuck at one value. The motor can be adjusted across its control range, including down to zero on the series description. That lets the same unit cover different torque and speed conditions. Higher displacement usually means more torque and lower speed for a given flow. Lower displacement moves the behavior the other way.
The operating numbers come from flow, pressure, and displacement working together
The technical relationships are straightforward: inlet flow is tied to displacement and rotational speed, while torque is tied to displacement and differential pressure. So when customers size an AA6VM, they are really balancing three things at once: target speed, available flow, and the torque the drive actually has to make.

FAQ Display Content
1) Is AA6VM a pump or a motor?
AA6VM is a hydraulic motor. It takes hydraulic power and turns it into shaft rotation. A pump works the other way around.
2) Can AA6VM work in both open and closed circuits?
Yes. It can be used in both, which is why this series appears in different hydrostatic drive systems.
3) Is the displacement fixed?
No. AA6VM is a variable motor. One of its key features is that the displacement can be adjusted, including down to zero on the series design.
4) What control types are common?
Common Series 63 control options include HD, EP, HZ, EZ, HA, and DA. The right one depends on how the machine is controlled-proportional, two-position, pressure-related, or speed-related.
5) Can you supply flushing or boost-pressure valve versions?
Yes, those versions are available. Some configurations also come with counterbalance-valve arrangements. For actual orders, though, the full model code and port plate details should be checked first.
6) What is the difference between AA6VM and a piston pump?
They do different jobs. A piston pump converts mechanical input into hydraulic flow. AA6VM converts hydraulic flow into mechanical rotary output.
7) How do I choose the right size?
Start with four points: required torque, required speed, available flow, and working pressure. In simple terms, torque is linked to displacement and pressure difference, while speed depends mainly on flow and displacement.
8) What do you need before quoting?
The full model code is best. If that is not available, send photos of the old unit, plus the shaft type, flange, control type, port plate direction, and machine application. Those details matter early, because AA6VM comes in different sizes, controls, shafts, and port layouts.
