The development and implementation of high-level product energy efficiency standards, especially advanced energy efficiency standards, is of great significance for the transformation and upgrading of the industry. It is conducive to guiding and promoting production enterprises to actively engage in technological innovation, and promoting the research and application of new structures, processes, and materials in the industry. For the motor industry, both international and domestic motor energy efficiency standards have been in a continuous upgrading stage in recent years. There is a consensus internationally that IE3 is a mandatory energy efficiency standard. The improvement of motor energy efficiency standards is of great significance for the integration of the motor industry and the overall improvement of technical capabilities.

1、 Efficient international standards for motors

At present, more than ten countries and regions in the world have issued motor energy efficiency standards, and international motor energy efficiency standards are constantly improving, with a clear trend towards high efficiency in motor international standards.

The International Electrotechnical Commission (IEC) has unified the global motor energy efficiency standards into four levels: IE1, IE2, IE3, IE4, etc. IE1 is designated as standard efficiency, IE2 as high efficiency, and IE3 as ultra-high efficiency, and has released their standard values. In 2014, the IEC organization released IEC 60034-30-1, expanding the motor power range to include motors ranging from 0.12KW to 1000KW, and officially released the IE4 energy efficiency standard values.

The new EU directive on ecological design of electric motors, EC No. 640/2009, was officially introduced on July 22, 2009. The EU has set a specific timetable for mandatory standards for IE3 motors. The specific execution of this instruction is divided into a three-step plan, and the schedule is as follows:

IEC60034-30-1 International Standard GB18613-2012 China 2012 Edition GB18613-2006 China 2006 Edition

IE4 Energy Efficiency Level 1

IE3 Energy Efficiency Level 2 Energy Efficiency Level 1

IE2 Energy Efficiency Level 3 Energy Efficiency Level 2

IE1

Energy efficiency level three

2、 Energy Efficiency Standards for Electric Motors in China

GB18613-2012

Requirements for target energy efficiency limit values

China is one of the major countries in the world for the production and manufacturing of electric motors. High efficiency motors are the future development direction of the motor market. In order to bring our motor products to the global market, it is necessary to ensure that the energy efficiency level of motor products meets the technical requirements of the international market. The current energy efficiency standard referred to in China's motor industry is the national standard "Energy Efficiency Limit Values and Energy Efficiency Grades for Small and Medium Three phase Asynchronous Motors" released in 2012. According to the recommendations of GB18613-2012, the target energy efficiency limit value for motors is a recommended recommendation, which requires that the efficiency at rated output power should not be lower than the Level 2 energy efficiency standard. Enterprises are encouraged to develop and produce IE3 motors to achieve the world level of energy efficiency in China. The specific implementation suggestions are as follows:

For motors with a rated power range of 7.5-375kW, the target energy efficiency limit value will be officially implemented 4 years after the implementation of GB18613 standard;

For motors with a rated power of 7.5 kW or less, the target energy efficiency limit value will be implemented 5 years after the implementation of the GB18613-2012 standard.

Domestic and international motor energy efficiency standards continue to upgrade, motor
