Break the way

The current priority is to speed up the elimination of outdated motors. According to the national standard "GB18613-2006", the motor industry has adopted the energy efficiency secondary (high efficiency motor) as the mandatory standard since July 1, 2011, and the motor below the energy efficiency secondary level is not allowed to be produced and sold. According to the new national standard of "energy efficiency limit value and energy efficiency rating of small and medium-sized three-phase asynchronous motor", Y-, Y2, Y3 series three-phase asynchronous motors produced in large quantities in China are also prohibited from production.

"Prohibition of production is far from enough. It is necessary to formulate a roadmap for the elimination of inefficient motors, phase out the use of low-efficiency backward motors, and guide enterprises to replace inefficient motors with high-efficiency motors. The motors are included in the scope of eliminating backward production inspectors, and the annual consumption. Enterprises with a certain size or above will carry out tests and guide enterprises to adopt the technology of variable frequency speed regulation to transform the motor system. The punitive electricity price will be implemented for enterprises that still use low-efficiency motors, so that the inefficient motors will gradually withdraw from the application market. Li Helan, project manager of the promoted energy service company, said.

Xu Shaoshan believes that in addition to mandatory measures. It is also possible to select provinces (cities) with good industrial base, strong technical strength and certain scale advantages to carry out pilot projects for efficient motor remanufacturing. Explore mechanisms such as trade-in, large-scale user-oriented repo, and promote the construction of the old motor recycling system. Accelerate the construction of remanufacturing basic capabilities and standards. Organize research and development of motor efficient remanufacturing products.

The Ministry of Industry and Information Technology will promote the contract energy management model and integrate professional energy-saving service companies, financial institutions, and third-party energy-saving certification organizations to adopt a “zero-input” upgrade model to help enterprises improve motor energy efficiency.

Zhao Yuejin believes that if the "zero input" mode is adopted, the energy-saving service company can select the energy-saving benefit sharing type and other modes to carry out energy-saving transformation of the motor system according to the requirements of the enterprise, which can greatly improve the enthusiasm of the enterprise's motor energy efficiency improvement. In addition, he believes that the central and local governments should increase financial support and focus on the improvement of motor energy efficiency.

International motor expert and ContopU.Brunner, the founder of top10 in Switzerland, introduced some measures to promote motor energy conservation in some countries in Europe and America. For example, the United States enacted the Energy Policy Act in 1992 to stipulate the minimum efficiency value of the motor; the EU has promulgated the energy-consuming product ecology. The Design Directive and the Energy Labeling Framework Directive; the United States began to enforce high-efficiency motors in 1997, and in 2011 forced the implementation of ultra-efficient motors; Europe also began to enforce high-efficiency motors in 2011, effectively promoting the improvement of motor energy efficiency. The effect is good. These practices can be used by China.

The newly issued "National Motor Energy Efficiency Improvement Plan" mentioned that in 2015, China will upgrade its motor products, and 50% of low-voltage three-phase cage asynchronous motor products and 40% of high-voltage motor products will meet the high-efficiency motor energy efficiency standard specifications; It will accumulate a total of 170 million kilowatts of high-efficiency motors, eliminate 160 million kilowatts of low-efficiency motors, implement 100 million kilowatts of energy-saving technology for motor systems, and implement 20 million kilowatts of high-efficiency remanufactured motors.

Gao Dongsheng, deputy director of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, said in an interview with the media: "Focus on the motor energy efficiency improvement plan, we must focus on key industrial enterprises." According to statistics, the annual national electricity consumption is 10 million kilowatts. At least 30,000 key industrial enterprises have been used, and the total electricity consumption accounts for about 80% of the total industrial electricity consumption. Key electricity companies play an important role in fulfilling the objectives and tasks of the motor energy efficiency improvement plan. He expects to save 80 billion kWh in 2015, equivalent to saving 26 million tons of standard coal and reducing carbon dioxide emissions by 68 million tons.

A motor revolution has been launched nationwide. Guangdong, Sichuan, Gansu, Hubei and other provinces have developed their own regional motor energy efficiency improvement plans based on local conditions. Wuhan, Sanya and other places subsidize enterprises that use high-efficiency motors, of which Wuhan gives a motor subsidy price of 5% to 7%, while Sanya subsidizes 40 yuan per kilowatt according to the capacity of the motor to be eliminated.
