Axial piston motors Manufacturers online

Axial piston motors are a special type of hydraulic motor that generate mechanical energy (rotary motion) from hydraulic energy.

They are primarily used in applications with high torques and variable speeds. Their operating principle is based on the axial arrangement of the pistons, which move in a cylinder block.

Below you will find the operating principle and types of axial piston motors, 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 rotating motion. The main components are:

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

Types of axial piston motors:

There are two main types of axial piston motors:

1. Swashplate motors: In this design, the pistons are arranged parallel to the axis of rotation, and the swashplate absorbs the piston movement and thus generates the rotary motion.
2. Inclined-axis engines: The pistons are housed in a cylinder block inclined at an angle to the axis of rotation. The piston movement is converted into a rotary movement by the inclined position.

Use of axial piston motors:

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

1. Mobile applications:
As a traction drive in construction machinery such as excavators, wheel loaders and cranes.
As a drive in agricultural machinery such as tractors and combine harvesters.

2. Maritime use:
As marine drives or as a drive for winches.

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

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

Advantages of axial piston motors:

• Low energy losses due to precise design.
• High power density with low volume.
• The speed can be easily controlled by adjusting the volume flow.
• Can be operated as a pump when an external force is applied to 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 areas.

Here are the most important aspects to look out for when buying axial piston motors:

Various technical, economic and qualitative factors play a role when purchasing axial piston motors. To make the best choice, the following criteria should be taken into account when purchasing.

• Carefully determine the technical requirements necessary for the intended use:
• Pressure range: Maximum operating pressure (e.g. 280 bar, 350 bar)
• Torque: Calculate to suit the application (Nm)
• Speed range: Minimum and maximum (rpm)
• Slip and efficiency: Observe efficiency
• Is the design and size suitable for your application?
• Is a swashplate or bent axis motor suitable for the application?
• Which type of mounting is suitable: flange, shaft or foot mounting?
• Consider the space available in the machine.
• The weight has an influence on 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 has an environmentally friendly design and whether biological or environmentally compatible hydraulic oils are compatible.
• Is an electronic or manual control system advisable?
• Observe certifications and standards: ISO 9001: Quality assurance. CE marking: Compliance with European safety requirements
• If the drive is required for potentially explosive atmospheres, take note of the ATEX certification!
• Good technical support and reliable availability of spare parts are also important.
• Pay attention to the material quality (hardened steel, hardened piston tracks). The sealing systems against leakage and contamination as well as the resistance to dirt and moisture.
• Place value on a good price-performance ratio. Consider not only the purchase costs, but also maintenance and energy consumption.
• Higher efficiency saves operating costs and longer service life means lower spare parts costs.
• Can you fall back on standard products or is the supplier able to implement custom-made products quickly and flexibly?
• The warranty should be at least 12-24 months.
• Does the supplier offer the option of a maintenance contract?

The purchase of hydraulic axial piston motors requires a detailed analysis of the technical requirements, an assessment of the manufacturer's quality as well as an economic and ecological consideration. Targeted selection can not only optimize performance, but also reduce operating costs in the long term.

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