1、 Concept of motor shaft
The motor shaft refers to the central axis of the motor rotor, which is the shaft connecting the motor rotor and the motor load. The motor shaft extends from the central axis of the motor rotor and can be made of materials such as steel, aluminum alloy, etc. The quality and material of the motor shaft directly affect the performance and lifespan of the motor.
2、 Classification of motor shafts
According to the size and function of the motor shaft, it can be divided into two types: small shaft and large shaft.
1. Small axis
A small shaft refers to a motor shaft with a diameter of less than 20mm. Small shafts are generally used for small motors, such as micro motors, small electric tools, etc. The advantage of a small axis is its small size and light weight, making it suitable for application in small spaces. The disadvantage is that the torque and strength are not as good as the main shaft.
2. Main axis
A large shaft refers to a motor shaft with a diameter greater than 20mm. Large shafts are generally used for large motors, such as industrial motors, generator sets, etc. The advantages of a large shaft are high torque and strength, making it suitable for high load and high-strength working environments. The disadvantages are large volume and heavy weight.
3、 Application scenarios of motor shafts
The motor shaft plays a crucial role in the motor drive system, and different types of motor shafts are suitable for different application scenarios. For example:
1. Small axis motors are suitable for small household appliances, small robots, medical equipment, etc;
2. Medium axis motors are suitable for industrial assembly lines, heavy-duty processing machinery, etc;
3. The large axis motor is suitable for mold processing, large-scale mechanical processing, etc.
4、 Summary
The motor shaft is an indispensable component of the motor drive system. According to the size of the motor shaft and the different application scenarios, the motor shaft can be divided into two types: small shaft and large shaft. In practical applications, it is necessary to select the appropriate motor shaft according to the actual situation to achieve the best working effect and lifespan.
