Compared with the more distant intelligent motors, high-efficiency motors have already been realized in technology. In recent years, the state has continued to increase the promotion of high-efficiency motors, and many policies have been introduced, including financial subsidies, but the effect is not obvious. According to the data, the current high-efficiency motor in the national memory is only about 8%.
From a technical point of view, at present, high-efficiency motors are mainly used in the industrial field in China. Huang Ziyang said that high-efficiency motors are not obvious in energy saving in home applications, but when applied in industry, the effect is very obvious. : "For example, the air conditioner can not work continuously for 24 hours. It is very power-hungry when the switch is turned off, so the air conditioner does not see this effect. The refrigerator usually runs 24 hours, but its power is low, and the power of 0.5W can be saved to 0.45. W, the effect is not obvious. Only the industrial power of the motor is large, 24 hours of continuous operation, the use of high-efficiency motor can clearly show the effect of energy saving."
From the consumer's point of view, high price is also one of the important reasons that affect the popularization of high-efficiency motors. Yu Zhijie said that the overall structure of high-efficiency motors is more complicated than general motors, and the price from inverter motors to chips is more expensive than ordinary motors. As a result, the price of the final high-efficiency motor is high, and it is unacceptable to ordinary users, resulting in low popularity. However, Tao Jianping believes that low popularity also means that high-efficiency motors have great market space, and it is recommended that micro-motor companies should pay attention to this market.
On the whole, the effect of high-efficiency motors in household use is not obvious at present, and the high price has become a hindrance to the difficulty of popularization of high-efficiency motors. The country's main push for green energy-saving, high-efficiency motor applications have always been a hot spot for industry players.
Great potential for motor remanufacturing
Whether it is a smart motor or a high-efficiency motor, it is based on energy conservation and environmental protection. In addition, motor recycling and remanufacturing are gradually receiving attention from the government and micro-motor enterprises. Since 2005, the State Council, the Ministry of Commerce, the National Development and Reform Commission, and the Ministry of Industry and Information Technology Many ministries and commissions began to introduce relevant policies to promote and support the development of China's remanufacturing industry. In July 2013, the National Development and Reform Commission, the Ministry of Industry and Information Technology and other ministries jointly issued a document to carry out the pilot work of re-manufacturing products to replace the old ones.
In March this year, in order to speed up the elimination of high-energy-poor backward mechanical and electrical equipment (products), the Ministry of Industry and Information Technology combined with the actual situation of industrial energy-saving and emission reduction work, through the declaration of manufacturers and industrial users, relevant industry associations and expert review, proposed "high energy-consuming backward mechanical and electrical equipment. (Product) Elimination Catalogue (Fourth Batch) and publicize it. With the increasing demand for remanufactured products in the field of electromechanical products in China, more and more manufacturers will join the ranks of remanufacturing, and the market for motor remanufacturing has great potential.
The motor remanufacturing market has great potential, but there are only a handful of companies that have made progress in this area. Tao Jianping said that motor remanufacturing is similar to refurbishment, which will easily cause people to worry about the quality of the motor after remanufacturing, so people entering this market are very cautious. Chen Jintao said that the current remanufacturing can not be rushed. He said that the first step is to establish recycling standards in China, to make the recycling rate first, and then to consider remanufacturing. He said: "Foreign companies are required to have a certain copper-iron-aluminum recovery rate. There is no relevant standard in China. Therefore, we should first set the standard and start the recycling rate first, then consider the motor remanufacturing. This area is mainly because it is a technology with large investment and long payback period. The return period may be around 10 years. Many companies may not have reached this step. But from the perspective of the company itself, motor remanufacturing is In order to save energy in green, it is necessary to make green design when designing products, which is to maximize the application of product materials and reduce product consumption without sacrificing product performance."
