What is the IP protection level of the motor?

Date：2024-04-18　　　Author：XINDA MOTOR

In industrial production, especially electronic and electrical products that can be used outdoors, equipment will have different levels of dustproof and waterproof requirements. The shell protection level (IP code/dustproof and waterproof) of automated instrumentation equipment is an important indicator to ensure the normal operation of the equipment and the safety and reliability of the product. Then, when selecting and using instrument products, you must pay special attention to the protection level of the instrument. This is of great significance for correct product selection, product installation and use. Below, I will give you a detailed introduction to the relevant knowledge of IP protection level.

What is the IP protection level?

To define the shell sealing performance of electrical equipment such as inkjet printer equipment, the EN60529 standard is commonly used internationally. The different categories of protection levels that this standard will quantify mainly include protection against the intrusion of solid foreign objects into the housing (including tools, fingers or dust, etc.) and protection against water (water entering the housing through condensation, flushing, immersion, etc., causing harm to the equipment) Influence).

The two digits after the IP indicate the protection strength of the equipment shell against solid foreign objects and water intrusion. The first number indicates the level of dustproofing and preventing the intrusion of foreign objects by the electrical equipment. The second number indicates the level of protection of the equipment against moisture and water intrusion. The degree of sealing, the larger the number, the higher the protection level.

For example: protection level IP54 , IP is the marking letter, the number 5 is the first marking number, 4 is the second marking number. The first marking number indicates the level of contact protection and foreign object protection, and the second marking number indicates the level of waterproof protection.

The protection levels represented by the two marked numbers are as follows:

In addition, when the level of protection requirements is higher than the level indicated by the above characteristic numbers, the extended range will be expressed by adding additional letters after the first 2 digits, and it will also need to meet the respective requirements of these additional letters.

Detailed classification of IP waterproof levels

The following waterproof grade reference standards are IEC60529, GB4208, GB/T10485-2007, DIN40050-9, ISO20653, ISO16750 and other international applicable standards:

Place the sample on the sample stage so that the distance from the top to the sample water nozzle is no more than 200mm and the sample stage does not rotate.

Test conditions: The water flow rate is calculated based on the number of water spray holes in the swing pipe, and each hole is 0.07 L/min. When water is sprayed, the water spray holes in the 60° arc segments on both sides of the midpoint of the swing tube are sprayed towards the sample. The tested sample is placed in the center of the semicircle of the pendulum tube. The swing tube swings 60° on both sides of the vertical line, totaling 120°. Each swing (2×120°) takes about 4 seconds.

Test pressure: 400kPa; Test time: continuous water spraying for 10 minutes; the sample rotates 90° after 5 minutes of testing

b. Sprinkler type water test

Test equipment: handheld water splash test device,

Sample placement: Make the parallel distance from the top of the test to the water nozzle of the handheld nozzle between 300mm and 500mm

Test conditions: A baffle with a counterweight should be installed during the test, and the water flow rate is 10L/min.

Test time: Calculated based on the surface area of the shell of the sample being tested, 1 minute per square meter (excluding installation area), minimum 5 minutes.

(4)IPX4
