First, the system of small asynchronous motor

 

Small asynchronous motor can be divided into three series: basic, derivative and special.

 

1. The basic series of small asynchronous motors are widely used, and the production output is also very large. They are universal motors.

 

2. The small asynchronous motors of the derived series have made relevant changes in the basic series mentioned above according to the requirements of different aspects of use. At the same time, the most basic series of corresponding components have high universality, and also have a certain degree of unity.

 

3. The purpose of the small asynchronous motor of the special series is different from that of the ordinary motor just now. It has more special requirements for use, and also has very special protection conditions.

 

II. Structural type of enclosure protection

 

This kind of motor has two corresponding protection levels, mainly including IP23 and IP2IP44. The IP in the front represents the universal and symbolic symbol of protection rating, while the first digit in the following number can prevent the contact of fingers in the relevant aspects, thus preventing small solid substances larger than 12 mm from entering the motor, The second digit is the corresponding angle, which should not harm the motor when pouring water.

 

III. Installation structure and motor form

 

It can be mainly divided into three categories: installation of foundation, cover installation by using a section of the flange attached to the foundation, and cover installation by using a protruding flange end. According to the relevant basic and relevant installation structure, the motor can be subdivided into horizontal or vertical installation and corresponding axial up or down extension.

 

The above is some basic knowledge about motor selection, and I hope it can help the majority of users.
