OMM Hydraulic Orbital Motor

 

OMM hydraulic motors are a type of hydraulic motor that use a axial distribution structure and a columnar stator and rotor design. These motors are known for their high mechanical efficiency and are widely used in various industrial applications.

 

 

The axial distribution structure of the OMM hydraulic motor ensures that both the rotor and stator have good axial stability, which helps the motor to operate efficiently and with minimal wear and tear. This structure also results in uniform load distribution, which helps prolong the life of the motor.

 

 

The stator and rotor design of the OMM hydraulic motor is columnar in shape. This design provides several advantages over other types of hydraulic motors. First, it ensures that the motor has a high torque density, which means that it can generate a high amount of torque with a relatively small frame size. Second, the columnar design helps to reduce hydraulic losses, resulting in higher mechanical efficiency.

 

 

One of the main advantages of the OMM hydraulic motor is its high mechanical efficiency. This motor achieves high efficiency thanks to its axial distribution structure and columnar stator and rotor design. The columnar design helps to reduce hydraulic losses and ensure uniform load distribution, while the axial distribution structure ensures that both the rotor and stator have good axial stability, resulting in minimal wear and tear.

 

 

The OMM hydraulic motor is widely used in various industrial applications, including agriculture, construction, marine, and mining equipment. It is commonly used in power steering systems, winches, conveyors, material handling equipment, and many other applications where high torque and efficient power transmission are required.

 

OMM hydraulic motors are an excellent choice for any industrial application where high mechanical efficiency and uniform load distribution are important. Their axial distribution structure and columnar stator and rotor design make them highly efficient and reliable. They are widely used in various industries and have proven to be an effective and reliable solution for many different applications.

◎ The intermittent operating pressure refers to the Max. allowable operating pressure at the motor inlet port, and the continuous operating pressure refers to the pressure difference between the inlet port and the return port.
◎ Do not operate the motor at the Max. speed and the Max. pressure at the same time.
◎ The motor operating time per minute must not exceed 10% under intermittent operating conditions.
◎ Recommended oil: anti-wear hydraulic oil; Viscosity: 37-73cst; Oil cleanliness: IS018/13.
◎ The Max. oil temperature should be 80℃.
◎ The series motor adopt special imported shaft seal assembly. The Max. allowable back pressure of the motor can be up to 10MPa; however, in order to obtain the good service life and comprehensive mechanical performances, the back pressure should not exceed 5MPa. If it is exceeded, it is recommended to connect the external drain pipe; when connecting the external drain pipe, ensure that the motor is always filled with oil. When connecting the external drain pipe, in addition to maintaining a low back pressure, the wear contaminants generated inside the motor can be removed and a certain cooling effect can be achieved.
◎ There should be a running-in period before the motor is operated at full load. It is recommended to run for 1h at 30% of the Max. operating pressure.
