At present, the industry's biggest concern is that the development of large domestic high-efficiency motors will have an impact on China's motor industry exports.
It is understood that China is the world's largest motor exporter, with exports accounting for about 10% of total motor production. In 2007, China's motor export volume was 25.99 million kW, accounting for 13.0% of the total output; in 2008, the export volume further increased to 28.47 million kW, the proportion rose to 13.8%; in 2009, the export volume decreased significantly, only 18.61 million kW, the export volume recovered in 2010, close to the highest level in history, reaching 27.43 million kW, an increase of nearly 50% compared with 2009, accounting for 11.4% of the total output.
Yan Yongbin, president of China General Machinery Industry Association, told this reporter that China's motor industry has broad prospects for development. Now there are fewer and fewer enterprises engaged in traditional motor production in developed countries such as the United States, and they are importing motors from abroad. This has brought huge business opportunities to China. In other words, China may become the manufacturing factory of the future world motor. How to increase the international competitiveness of domestic motor manufacturing enterprises is a key issue we have to solve.
According to an industry expert, large foreign motors are now moving toward light and simple development. China's large-scale high-efficiency motor exports obviously have no advantage.
It is understood that after 2000, the world's famous motor manufacturers have launched their latest series of medium and large high-voltage asynchronous motors. ABB has launched the AMA series, and Japan TMEIC has introduced the TM21 series. The efficiency values of these series of motors. Most of them do not meet the specified efficiency values of high-efficiency motors in China, but their common feature is that the volume and weight of motors are significantly lower than those of their old series. Compared with the standard series of products of the same capacity in China, the weight of them should be It is about 30% lighter, and compared with the high-efficiency motors of many manufacturers in China, the weight difference is even larger.
Calculated by a large-capacity high-voltage asynchronous motor with a unit of kilowatts of 7.5 kilograms, the annual output of high-voltage asynchronous motors in China is 50 million kilowatts. If the weight of the motor is reduced by 30%, the country can save about 125,000 tons of steel and copper annually. . The fact that the size and materials of the motor greatly exceeds that of foreign motors has seriously weakened our international competitiveness in the motor industry. The large amount of materials we consume may indeed make our medium and large motors more than a few percentage points more efficient than foreign motors, but will foreign users use our motors for higher prices? The answer is obvious. The above professionals said to this reporter.
For the development of large-scale high-efficiency motors, some experts suggest that large-scale motors should take a systematic and energy-saving route, that is, optimize and modify the entire motor system, such as adding inverters, etc., the energy-saving effect is very obvious; small motors are firmly Promote the route of high-efficiency motors, because the small-capacity motor can easily increase the efficiency of the motor by several percentage points after appropriately increasing the amount of materials.
However, some experts hold different opinions. Xiong Huawen, deputy director of the Energy Efficiency Center of the Energy Research Institute of the National Development and Reform Commission, said in an interview with this reporter that the state should adopt a non-discriminatory attitude towards high-efficiency motors. Large-scale high-efficiency motors are indeed more energy-efficient than ordinary motors. The national subsidy policy is also to encourage enterprises to improve technological innovation. force. As for whether to use large and efficient motors, it should be decided by users and the market. The urgent task now is to establish a viable energy efficiency rating system and standards, just like small and medium-sized motors. At present, relevant departments have completed research on manufacturers, and the formulation of standards will be the next step.
