Automotive motor controller principle and technology development trend

“With the new changes in the external situation, the operation of the machinery industry has shown a new trend this year, and the operation situation of the sub-sectors has been clearly differentiated.” At the launch conference of the 2019 mechanic think tank held recently, the executive vice president of the China Machinery Industry Federation Xue Yiping introduced the operation of the machinery industry this year.

    The robot industry has grown rapidly and has become the new engine of the industry. From January to March, the operating income of the non-automotive industry in the machinery industry increased by 11.76% year-on-year, and the operating income of 13 sub-sectors showed an increase. Among them, the robotics and intelligent manufacturing industry, driven by market demand, operating revenue growth rate of more than 20%, is a new bright spot in the machinery industry this year; heavy mining, petrochemical general industry in the upstream raw material industry equipment transformation and upgrading demand, business The income growth rate has increased by 10%-20%; the income of machine tool manufacturing, mechanical basic parts and internal combustion engine industry has been generally stable, with an increase of around 8%. The performance of the automobile manufacturing industry was relatively sluggish, and both operating income and total profit declined, but the decline was narrower than that in January-February.

    The export turned from negative to positive, and the industry has picked up. From January to March, the machinery industry exported 103.715 billion US dollars, a year-on-year growth rate from negative to positive, an increase of 1.77%. Exports from 11 of the 14 major sub-sectors increased, up from 10 in January-February. Among them, the export of agricultural machinery, food packaging equipment and robotics and intelligent manufacturing industry increased by more than 10%, the export growth of machine tools, mechanical basic parts and other civil machinery industries was around 5%, and the export growth of other industries was around 1%. From the perspective of the nature of enterprises, the export of private enterprises increased by 8.36% year-on-year.

    "Although there have been some situations that need to be concerned about the operation of the industry, there has been no fundamental change in the stable operation of the machinery industry. The trend of industrial development will remain, and new development forces are accumulating and expanding." Xue Yiping said.

    In response to the new changes and new challenges, Wu Shuang, a researcher at the mechanics think tank, suggested that machinery companies should promote technological transformation and commercial capacity building in a step-by-step manner to achieve transformation and upgrading. For example, for enterprises that have achieved efficient production under the traditional model, they should explore new business formats and new models to enhance economies of scale and efficiency by integrating internal and external resources. For small and micro enterprises, it is necessary to improve leanness and standardization. .

    “A lot of companies think that they need to engage in intelligent manufacturing when they think about transformation and upgrading, but we are against blind intelligent manufacturing.” Wu Shuang said that information technology is based on a lean management system, and intelligentization is based on the deployment of information-based facilities. To achieve smart manufacturing, you must be prepared accordingly. Enterprises should be clear about the industry characteristics and development stage in which they are located, choose the appropriate transformation route, first lay a solid foundation, and then build their own skyscrapers layer by layer.

    In addition, the mechanic think tank suggests that under the new pattern of scientific and technological revolution and industrial transformation, enterprises should also strive to have five major genes, namely, market view genes, and open up new types of consumption methods and lifestyles by finding specific market segments. And production methods; cognitive genes, efforts to have a complete industrial knowledge system and deep technical accumulation to form the ability to respond quickly to individual needs; factor view genes, the formation of their own technology, digestion, absorption and innovation; ecological outlook Through the coordination ability within the industrial cluster, the gene not only fully grasps the development trend of the industry, but also builds a reliable, efficient and economical supply chain system; organizes the genes, and through the strong product organization and manufacturing capabilities, forms a higher productivity.
