How to select an orbital Motor

2025-07-07

orbital Motor is a low-speed multi-torque hydraulic motor, it has a wide range of applications in engineering machinery, petroleum machinery, light machinery, agricultural machinery and other equipment. Foreign production of the main manufacturers are: Denmark's Danfoss, the United States EATON-Char-lynn company, the United States White drive company, Italy SAM company. Domestic manufacturers are more like hair, the size of dozens of manufacturers, Hanjiu company is one of them. orbital Motor has formed more than a dozen series of dozens of specifications, displacement 8-1250cc / r, the import of continuous pressure of 10-20Mpa, speed 5-1000rpm, the output of the rated torque of 20-1960Nm, the total efficiency of up to 85% or more. In short, this motor is a simple and compact structure, small volume, small quality, low-speed performance, a wide range of speed, low price, wide range of uses, the use of reliable low-speed medium-torque hydraulic motor.

 

The orbital Motor can be categorized into shaft-flow motor, disk-flow motor, and valve-flow motor according to the flow distribution method, which is the most conventional way of categorization.

 

Some orbital motors are designed with a speed sensor.

 

Some orbital motors are designed with a brake. (Brake principle: spring loaded, hydraulically released)

 

Some orbital motors are designed with their own clutch. (Motor operates normally when pressurized oil is fed to the end of the motor; motor output shaft is free when no pressurized oil is fed to the end of the motor.)

 

Some orbital motors have been used to drive small vehicles, and the motor is designed to be driven on the side of the wheel. (Wheel drive orbital motor)

 

There are many different types of Orbital Motors, and the specific type of orbital motor to be selected needs to be analyzed in relation to the requirements of the use. To summarize, the following factors should be considered when selecting an orbital motor:

1.the need for motor torque size, of course, first to determine the system pressure, hydraulic motor torque output and system pressure has a direct relationship.

2.the need for motor speed

3.According to the motor connection form to consider the back pressure of the motor, the tandem system in particular, the main motor back pressure.

4.according to the motor system to consider the size of the motor back pressure, a lot of agricultural machinery auxiliary motor back pressure up to 60bar.

5.pay special attention to the motor can withstand the back pressure and motor output speed is directly related to the motor output speed, the higher the motor output speed, can withstand the back pressure is smaller, please see the manufacturer's samples.

6.hydraulic motor installation requirements and volume requirements, determine the shell and output shaft.

7.Choose the commonly used models, so that the delivery time and price has the advantage.
