Motor Energy Saving Effectively Promotes Industrial Energy Saving

"Now we have gradually entered an era of talking with standards. Whoever can take the lead in seizing the right to standard speech will be more likely to stand out and guide the future direction of market competition," said Ma Lincong, dean of the China National Institute of Standardization.

The “Outline for Quality Development (2011-2020)” issued by China in 2012 clearly defines the role that standards play in promoting development and ensuring development. At the Third Plenary Session of the 18th CPC Central Committee, the "standard" was again mentioned by the policy makers.

Statistics show that the electrical power consumption of industrial fields accounts for about 75% of the total amount of industrial electricity, and the energy conservation of electrical motors is the key to industrial energy conservation. As a professional organization engaged in standardization in China, the China National Institute of Standardization has long been advancing the standardization of energy conservation and emission reduction.

The two energy efficiency standards reported on the WTO/TBT website indicate that the two energy efficiency standards submitted by the China National Standardization Administration have been publicized and will be put into use.

The two standard names are: the national standard of the People's Republic of China, "Energy efficiency limit value and energy efficiency rating of high-voltage three-phase cage asynchronous motors" and the national standard of the People's Republic of China "Energy efficiency limit values ​​and energy efficiency grades for permanent magnet synchronous motors". The Institute of Standardization formally developed the approved motor energy conservation standards on October 10th.

“Standardize the motor market, eliminate low energy efficiency products, save energy, and protect the environment”. The standard specifies the energy efficiency rating, energy efficiency limit value, energy conservation evaluation value and evaluation method for high-voltage three-phase cage asynchronous motors and permanent magnet synchronous motors. This can promote the improvement of the efficiency of major energy-consuming equipment such as motors.

As of September 2010, the China National Institute of Standardization held a meeting to establish the energy efficiency standards for high-voltage motors and permanent magnet synchronous motors, and defined the members of the standard drafting group and their work arrangements.

In March 2011, the China National Institute of Standardization took charge of the drafting of the “High-voltage Motor Energy Efficiency Limits and Energy Efficiency Ratings” and “Permanence Limits for Energy Efficiency of Permanent Magnet Synchronous Motors and Energy Efficiency Ratings”. In July of that year, two draft standards were issued.

On November 17, 2011, the drafting group held two seminars on the development of motor energy efficiency standards in Nanning, Guangxi. Representatives of well-known motor manufacturers from home and abroad, such as Shanghai Electric Power Institute, International Copper Association, Nanyang Explosion Protection Group and Siemens (China) Co., Ltd., attended the standard seminar.

On September 5, 2012, the second standard seminar was held in Shanghai and the last revised standard was discussed.

On September 8, 2012, according to the recommendations of the Shanghai Conference, a draft for the draft of the energy efficiency standard for high-voltage motors and permanent magnet synchronous motors was prepared, and an opinion solicitation letter was sent to motor manufacturers and related experts. A total of 60 letter of comments were issued. At the same time, the consultation materials were put on the website of China Energy Efficiency Labeling to widely solicit opinions from the society... Ma Lincong said at the national standardization work conference in 2013 that standard scientific research should be close to the market at the grassroots level. The standardization work must come from practice, then guide and standardize practice.

In this standard setting, members of the standard drafting group included representatives of grassroots companies such as Nanyang Explosion-proof Group and Siemens (China) Co., Ltd., and repeatedly solicited their opinions. Only one of the drafts was consulted on the effective treatment of 18 companies and experts. Opinion 53.

The interpretation of the national standard in the industrial chain is not only the formulation of new standards, but also responsibility for the revision of existing old standards.

The starting point of the motor energy efficiency standard, the China National Institute of Standardization finds a very accurate, injecting positive factors into the establishment and improvement of the ecological civilization system in the future.

In fact, in addition to the “Energy Efficiency Limiting Values ​​and Energy Efficiency Ratings of High-voltage Three-phase Squirrel-cage Induction Motors” and “Energy Efficient Limit Values ​​and Energy Efficiency Grades of Permanent Magnet Synchronous Motors”, on May 11, 2012, China’s previously implemented GB18613-2006 “small and medium-sized three-phase The energy efficiency limit value and energy efficiency rating of asynchronous motors was also revised and reissued by the China National Institute of Standardization.

GB18613-2006 "Limits and Energy Efficiency Ratings for Energy Efficiency of Small and Medium-sized Three-phase Asynchronous Motors" was first published in 2006. With the changes in the situation and conditions in recent years, the old standards need to keep pace with the times. The revision of this standard refers to the international standard for the classification of motor energy efficiency IEC 60034-30 "Single-speed three-phase cage induction motor efficiency classification", as far as possible with the international standards, but also fully consider the actual situation of China's motor products And the level of development makes the standard highly scientific, advanced, and operational.

From the new standard for small and medium-sized three-phase asynchronous motors, that is, GB18613-2012 "Limits and Energy Efficiency Ratings for Energy Efficiency of Small and Medium-sized Three-phase Asynchronous Motors," to "Energy-Efficiency Limiting Values ​​and Energy Efficiency Ratings for High-Voltage Three-phase Cage-Type Asynchronous Motors" and "Permanence Magnetism The limits of energy efficiency and energy efficiency of electric motors, the three national standards of the China Institute of Standards and Research, lead the direction of motor energy conservation.

As spring breeze bursts, the entire industry is blown green. The standard force covers all aspects of the motor industry chain. From standard formulation and revision to the adoption of standards, whether it is R&D, production, promotion of high-efficiency motors, efficient reengineering of inefficient motors, or elimination of inefficient use of motors for recycling, they have been incorporated into the perspective of standardization workers.
