In addition, low-voltage standard industrial motors are also widely used in other industrial fields, such as metallurgy, mining, petrochemicals, papermaking, etc. In these fields, motors, as one of the key equipment, are of great significance to ensuring the stability of the production process and improving production efficiency.

How are the energy efficiency grades of low-voltage standard industrial motors divided?

The energy efficiency grades of low-voltage standard industrial motors are mainly divided according to relevant national standards or international standards, which specify the efficiency level of motors under specific working conditions. The following is the general situation of the energy efficiency grade division of low-voltage standard industrial motors in my country:

1. Energy efficiency grade division standards
The energy efficiency grade standards of low-voltage motors in my country mainly refer to the GB 18613 series of standards, among which GB 18613-2020 "Energy Efficiency Limit Values ​​and Energy Efficiency Grades of Motors" is the latest version (Note: Although the latest standards may be updated, GB 18613-2020 is used as an example for explanation). According to this standard, the energy efficiency grades of low-voltage motors are usually divided into multiple grades, such as IE1, IE2, IE3, IE4, etc., among which IE4 is the highest energy efficiency grade.

2. Characteristics of each energy efficiency grade
IE1 grade:
The energy efficiency level is low, and it is a traditional low-efficiency product.
The efficiency is generally around 70%, the loss ratio of electrical energy converted into mechanical energy is high, and the energy consumption is large.
It is suitable for some occasions where energy efficiency is not high, but it should be gradually eliminated to reduce energy consumption.
IE2 level:
Medium efficiency level product.
The efficiency is generally around 80%, the loss ratio of electrical energy converted into mechanical energy is relatively low, and the relative energy consumption is low.
It is suitable for some medium and low load occasions, and it is a more common energy efficiency level on the market.
IE3 level:
High efficiency product.
The efficiency is generally above 90%, the loss ratio of electrical energy converted into mechanical energy is extremely low, the energy utilization efficiency is high, and the energy consumption is relatively low.
It is suitable for large and medium loads and regular working conditions, and it is an important choice for energy conservation and emission reduction.
IE4 level (may be included in some standards):
The highest energy efficiency level.
The energy efficiency is more than 30% higher than that of IE2 level motors, and it is also significantly higher than that of IE3 level motors.
It is suitable for large loads and special working conditions, such as machinery, pumps, fans, etc., and has extremely high energy efficiency requirements.

III. The importance of energy efficiency classification
The classification of low-voltage motor energy efficiency levels is of great significance to promoting energy conservation and emission reduction. By improving the energy efficiency level of motors, the operating costs of enterprises can be reduced, economic benefits can be improved, and energy consumption and environmental pollution can be reduced. Therefore, when selecting low-voltage motors, enterprises should choose appropriate energy efficiency levels based on actual needs and economic benefits, and strengthen the maintenance and management of motors to extend the service life of motors and further improve energy efficiency.
