THM – MFS – Fixed displacement axial piston motor

Description

THM – MFS – Fixed Displacement Axial Piston Motor

• Fixed Displacement Axial Piston Motor
• Max. pressure 420 bar
• Sizes: 33 to 90 cm³//rev

 

The THM – MFS Series fixed displacement axial piston motors are made to perform well even in tough hydraulic systems. Using a swashplate mechanism and built on the Sauer 20 Series, they are perfect for use with hydrostatic transmissions. The THM MFS range makes sure you get reliable and efficient operation, regardless of your need for speed or torque.

 

Product Overview

The main use of the THM MFS fixed displacement motor is in hydrostatic drive systems, since it delivers a constant and effective output. It uses hydraulic pressure and flow to create mechanical energy with the same amount of torque which is helpful for both mobile and industrial devices.

 

Key Features:

1. Swashplate design – Compact and effective for delivering power all the time
2. Bimetallic bearing plate – Designed to last for a long time.
3. Lightweight plunger – Guarantees good performance at high rotational speeds
4. Tapered roller bearings – They are designed to handle both high radial and axial shaft loads
5. Face or lip seals are used to ensure the system is well sealed from the outside
6. Follows SAE Standards – Meets the requirements set by the SAE
7. Hydraulic accessories can be added as an option to fit your needs

 

Working Principle

It is the swashplate principle that powers the THM – MFS axial piston motor. In this design, a number of pistons are parallel to the drive shaft and push against a rotating swashplate. This is how the process takes place:

A port allows hydraulic fluid to get into the motor and into the cylinder block where the pistons are found.

When the swashplate rotates, it makes the pistons move back and forth.

This action allows hydraulic energy to move the motor shaft and create torque on it.

The motor always produces the same torque and speed with each rotation which is set by the flow and pressure.

Thanks to this design, the motor provides constant power which is ideal for systems that do not constantly need to adjust their speed and torque.

 

Applications of THM – MFS Motors

This motor is used in many industries where steady torque and high dependability are required. These include:

 

1. Mobile Equipment

Machines used in agriculture such as harvesters and tractors

Equipment like skid steers and compact loaders is used in construction sites.

Forestry equipment and mobile crushers are used in this industry.

 

2. Industrial Machinery

Conveyor drive systems

Injection molding machines are used in the process.

Machines that use hydraulic drive motors

 

3. Hydrostatic Transmissions

Closed-loop drive systems that have a pump and a motor

Utility vehicles, road rollers and forklifts

 

4. Marine and Offshore Uses

Winch drives

Handling anchors is an important task.

Deck machinery

 

5. Renewable Energy

Wind turbine pitching systems

Systems that use hydraulic drives to follow the sun are available.

 

 

Types of Axial Piston Motors

Even though THM – MFS is a fixed displacement axial piston motor, it is helpful to know the main types of axial piston motors to see why it is strong:

 

1. Motors that have a fixed amount of movement.

Keep the torque and speed stable

A design that is both simple and strong

Ideal for situations that need a constant supply of power

 

2. Motors that use variable displacement designs

The swashplate can be adjusted to change how much fluid is displaced.

Used when it is important to control either speed or torque

The process gets more complicated and expensive.

This type of engine is fixed displacement which means it transfers energy efficiently, is easy to control and requires little maintenance.

 

Here is an example of a model code

THM MFS71/C1A35T is a motor.

This is a regular setup for the MFS Series and can be changed by adding various flange styles, shaft designs and hydraulic features.

 

 

Advantages of THM – MFS Series Motors

1. It can function effectively up to 420 bar which makes it perfect for tough industrial uses.
2. Swashplate design allows the engine to be both light and compact.
3. The bearing plate and seals are made with advanced materials, so the pump continues to work well in dusty, hot or humid conditions.
4. Because there are fewer parts involved, fewer services are required.
5. With a lightweight plunger, the machine can run at high speeds without becoming unstable or vibrating.
6. SAE mounting compatibility makes it easy for the device to be added to existing systems.

 

Maintenance Tips

For the motor to function well and last long, you should follow these important maintenance steps:

1. Check the Quality of Your Oil

Use hydraulic oil that is of high quality and has the right viscosity. Damaged or contaminated oil causes the engine to wear down and work less efficiently.

2. Make sure the seals are not broken.

Check the shaft seals often to see if they are leaking. Immediately replace seals when they are worn out to prevent losing pressure inside the engine.

3. Maintain clean Hydraulic Lines

All connections and hoses should be cleaned before you begin the installation. Dirt can lead to scratches on the insides of the material.

4. Routine checks of the operation

Look out for unusual sounds or vibrations, as they might signal that something is wrong with the alignment.

5. Maintain the Right Temperature

Avoid overheating. If the temperature is too high, it can harm the seals and cause the oil to break down which reduces the life of the motor.

If you need a reliable, efficient and powerful hydraulic drive, the THM – MFS Fixed Displacement Axial Piston Motor is the best choice. This motor is built with advanced features from the Sauer 20 Series and is very durable, so it is perfect for hydrostatic drive systems and other tough applications.

Because of its compact build, high torque and tough internal pieces, it performs well for a long time with little maintenance. In construction, agriculture, marine or industrial manufacturing, the THM MFS motor promises reliability, good performance and cost savings.
