The project belongs to the discipline of motor technology and is used for intelligent testing of three-phase asynchronous motors, variable frequency motors, electric vehicle motors, servo motors and other motors. The results come from the Industrial Technology Achievements Transformation Project of the Ministry of Finance and the Science and Technology Research Project of the Shanghai City Science and Technology Commission. The deep integration of the new generation of information technology and manufacturing has formed new production methods, industrial forms and new economic growth points. Digitalization and intelligence of manufacturing are the core technologies of the new industrial revolution, and the global industrial competition landscape is undergoing major adjustments. Faced with a dynamic and ever-changing market, countries have increased investment to seize market share. Well-known European motor manufacturers have adopted advanced intelligent production methods and have achieved high-quality, efficient and clean production. With the increase in labor costs and the gradual disappearance of the demographic dividend, our industrial motor industry can no longer follow the old path of labor-intensive production models commonly adopted in the motor industry. We must explore new automation, informatization, and intelligence. New manufacturing model. As the high-end testing link of the value chain and the core of the industrial chain, with the rise of high-end equipment manufacturing with intelligent manufacturing as the main direction, intelligent motor testing equipment has become a highland for global manufacturing competition. Therefore, carrying out research on key technologies of intelligent motor testing equipment and developing related equipment is the key and core of motor testing and manufacturing. It is imperative and has broad development prospects. It has important implications for the intelligent development of the motor industry and the implementation of the "Made in China 2025" manufacturing power strategy, energy conservation and emission reduction, etc. All have an important position and role. It has successively overcome core technologies such as quality evaluation and analysis technology based on big data, seamless detection adapted to a variety of special motors, and adaptive intelligent variable frequency power supplies; in& ldquo; Big Data Quality Evaluation and Analysis Expert System& rdquo;,& ldquo; Three feedback triple stable frequency conversion test power supply& rdquo;,& ldquo; Online black box test& rdquo;,& ldquo; DC power supply that simulates the operating characteristics of vehicle batteries& rdquo;,& ldquo; Online detection intelligent control& rdquo; A number of technological innovations have been made in other aspects, and the country's first comprehensive motor intelligent testing equipment has been developed. Industrial Ethernet technology has been used to realize interconnection with MES, PLM, ERP, etc., open up upper data flow, and integrate type testing and online testing. Control, data collection and processing, quality evaluation and other functions are integrated. It has the characteristics of self-learning, self-decision, self-execution, self-adaptation, high stability, and high precision, realizing true intelligent testing in the field of motor test equipment. Technical performance indicators of the project: load change rate 0.0425%, efficiency test uncertainty 0.36%, speed test accuracy le;0.01. torque test accuracy le;0.01. system online real-time performance le;20ms, among which, the uncertainty assessment is better than the requirements of IEC standards, and the comprehensive technical level has reached domestic leading and international advanced. This project has 20 valid patents, including 5 invention patents, 6 utility model patents, and 9 software copyrights. It has published 10 papers in domestic core journals and formulated 7 national standards. The results of this project have been successfully transferred to more than 30 key enterprises in the industry, achieving direct economic benefits of more than 200 million yuan, indirect economic benefits of more than 2.3 billion yuan, and significant economic benefits. The implementation of this project has filled the gap in my country's motor intelligent testing equipment and shortened the gap with foreign countries; improved the intelligent level of motor testing and achieved technical cost reduction and efficiency improvement; Provide necessary supporting conditions for the automation, informatization and intelligent process of motor manufacturing, optimize the overall design and manufacturing level of the motor industry, improve the overall technical level and market competitiveness of products, and more importantly, provide our country's "Made in China 2025" manufacturing power strategy, energy conservation and environmental protection industry development have made significant contributions and support.
