Axial piston motors – find manufacturers and suppliers

Axial piston motors convert hydraulic energy into mechanical rotational motion and are frequently used in mobile machinery or industrial equipment.

They are hydraulic machines in which several pistons are arranged parallel to the drive axis within a cylinder block and are driven by pressurized fluid.

Below you will find information on how axial piston motors work, the different types available, their areas of application, and their advantages:

How axial piston motors Work:

Axial piston motors are based on the hydrostatic principle and convert the pressure energy of a hydraulic fluid into rotational motion. The main components are:

1. The cylinder block contains several axially aligned pistons.
2. The movement of the pistons is converted into rotational motion by an inclined disc (inclined disc) or an inclined shaft (inclined shaft).
3. The control plate regulates the oil flow into the cylinders.
4. The drive shaft transmits the generated rotational motion.

Types of axial piston motors:

There are two main types of axial piston motors:

1. Swash plate motors:
   In this design, the pistons are arranged parallel to the axis of rotation, and the swash plate transmits the piston motion, thereby generating the rotational motion.
2. Oblique-axis motors:
   The pistons are housed in a cylinder block that is inclined at an angle to the axis of rotation.
   The piston motion is converted into rotational motion due to the inclined position.

Applications of axial piston motors:

Axial piston motors are used in various industrial and mobile applications, including:

1. Mobile applications:
As travel drives in construction machinery such as excavators, wheel loaders, and cranes.
As power units in agricultural machinery such as tractors and combine harvesters.

2. Maritime applications:
As ship propulsion systems or to power winches.

3. Industrial applications:
As drives in conveyor belts, conveyor systems, and production machinery.

4. In environmental technology:
For adjusting the rotor blades in wind turbines.

Advantages of axial piston motors:

• Low energy losses due to precise construction.
• High power density with low volume.
• Speed can be easily controlled by adjusting the flow rate.
• Can be operated as a pump when an external force acts on the shaft.

Axial piston motors are powerful and efficient drive systems for numerous applications. Their design enables high torques and precise control, making them indispensable in many fields.

Here are the most important factors to consider when purchasing axial piston motors:

Various technical, economic, and quality factors play a role when purchasing axial piston motors. To make the best choice, you should consider the following criteria during the purchase process.

• Carefully determine the technical requirements necessary for the intended application:
• Pressure range: Maximum operating pressure (e.g., 280 bar, 350 bar)
• Torque: Calculate based on the application (Nm)
• Speed range: Minimum and maximum (rpm)
• Slip and efficiency: Consider efficiency
• Are the design and size suitable for your application?
• Based on the application, is an angle-disc or angle-axis motor suitable?
• Which mounting type is suitable: flange, shaft, or foot mounting?
• Consider the space available inside the machine.
• Weight affects mobility and transportation costs.
• Are the valves and control plates compatible with the existing hydraulic system? Also consider compatibility with existing hydraulic oils (e.g., HLP, bio-oils).
• Check whether the motor features an environmentally friendly design and whether bio-based or environmentally compatible hydraulic oils are compatible.
• Is an electronic or manual control system appropriate?
• Consider certifications and standards: ISO 9001: Quality assurance. CE marking: Compliance with European safety requirements
• If the drive is required for potentially explosive atmospheres, be sure to check for ATEX certification!
• Good technical support and reliable spare parts availability are also important factors.
• Pay attention to material quality (hardened steel, hardened piston ways). Consider the sealing systems to prevent leakage and contamination, as well as resistance to dirt and moisture.
• Prioritize a good price-performance ratio. When doing so, consider not only the initial purchase cost but also maintenance and energy consumption.
• Higher efficiency saves operating costs, and longer service life means lower spare part costs.
• Can you rely on standard products, or is the supplier able to produce custom designs quickly and flexibly?
• The warranty should be at least 12–24 months.
• Does the supplier offer the option of a maintenance contract?

Purchasing hydraulic axial piston motors requires a detailed analysis of technical requirements, an assessment of the manufacturer’s quality, and consideration of economic and environmental factors. Through careful selection, you can not only optimize performance but also reduce operating costs in the long term.

Axial piston motors can be purchased from various suppliers. You can find comprehensive information about manufacturers and suppliers of Axial piston motors from around the world on Exportpages.
