What is a rotary motor
Swing motor is a common hydraulic or electric drive device widely used in construction machinery, industrial equipment and automation systems. Its core function is to achieve rotational motion and provide power support for mechanical equipment. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce in detail the definition, working principle, application fields and market trends of rotary motors.
1. Definition and classification of rotary motors
A swing motor, also known as a swing motor or swing drive, is a device that converts hydraulic or electrical energy into rotating mechanical energy. According to different driving methods, rotary motors can be divided into the following categories:
| type | Drive mode | Features |
|---|---|---|
| Hydraulic swing motor | Hydraulic oil driven | Large torque, fast response, suitable for heavy machinery |
| Electric swing motor | Electric drive | Energy saving, environmental protection, high control accuracy |
| Pneumatic rotary motor | Compressed air drive | Simple structure and good explosion-proof performance |
2. Working principle of rotary motor
The core working principle of a rotary motor is to drive the internal rotor or gear mechanism to rotate through the input of fluid (hydraulic oil or compressed air) or electricity, thereby outputting torque. Taking the hydraulic rotary motor as an example, its working process is as follows:
1. Hydraulic oil enters the oil inlet of the motor from the pump station;
2. Hydraulic oil drives the rotor or gear to rotate;
3. The rotational motion is transmitted to the external device through the output shaft;
4. The hydraulic oil that has completed the work returns to the tank from the oil return port.
3. Application fields of rotary motors
Slewing motors are widely used in the following fields due to their efficient rotational power output capabilities:
| Application areas | Typical equipment | effect |
|---|---|---|
| Construction machinery | Excavators, cranes | Driven slewing platform to achieve 360° rotation |
| Industrial automation | Robotic arm, turntable | Provides precise angular positioning |
| agricultural machinery | combine harvester | Drive the header to rotate |
| Ship equipment | marine crane | Realize the rotation and lifting of goods |
