In the coil workshop of the manufacturing center of xemc Co., Ltd., the deafening roar of equipment cannot be heard, and a "intelligent manufacturing revolution" that subverts tradition is quietly carried out here. Workers touch the control screen, and the gelling intelligent equipment between the turns of the integrated drying room runs accurately according to the instructions; In the stator welding area, the induction welding gun does not see open flame smoke, but it can weld a smoother and firmer weld. This "quiet" change stems from the fact that the xemc engineer team has focused on the three core problems of "precision, production capacity and stability" of coil manufacturing for decades, and has created the industry-leading "coil mother machine" hard power with independent innovation.

"The motor is the heart of industry, and the coil is the valve of the heart, and every difference affects the overall situation." Guo Xiaoling, chief technical engineer of the chief engineer office of xemc Technology Center, has always taken this sentence as the creed of the R&D team. In order to overcome the bottleneck of winding accuracy, she led the team to take root in the workshop for half a year, from copper wire material to tension control, repeatedly debugging parameters, dismantling difficulties, and finally developing an intelligent winding system to achieve "millimeter-level" precision control, reducing the copper loss of the coil by 10%, reducing the temperature rise and pressure drop by 18°C, and successfully breaking the monopoly of foreign technology.

In the face of the challenge of increasing production capacity, Liu Di, deputy director and engineer of the coil workshop, proposed a new idea of "modular production". By reconstructing the manufacturing process, the original 12 dispersed processes are integrated into 3 intelligent production lines, and with the self-developed integrated drying room inter-turn gelling equipment, the coil production efficiency is increased by 3 times.

In terms of extreme environmental adaptability, the team of Song Dacheng, head of the absolute chemical process and senior engineer of the Chief Division Office of the Technology Center, handed over outstanding results. In order to meet the stringent needs of offshore wind power and alpine rail transit, they spent two years testing hundreds of insulation materials, and finally developed special coil materials that are resistant to low temperatures of -45°C to 130°C and have resistance to salt spray exceeding international standards. The 12MW wind turbine equipped with this material has been operating stably in Fujian and Guangdong waters, transmitting more than 300 million kWh of clean electricity annually; Equipped with high-speed rail traction motors, it galloped on alpine and high-altitude lines at a speed of 350 kilometers per hour to achieve zero-failure operation for ten years.

From the laboratory to the workshop, from the domestic key project to the global market, the xemc engineer team interprets the true connotation of "Made in China" with the spirit of "more truthful". The coils they developed not only support the efficient operation of key projects such as the domestic 1.2 million tons of ethylene project, but also become a reliable business card for China's high-end equipment to "go overseas" with xemc Motor to the world.

"In the past 90 years, 'building heavy equipment and shouldering the mission' is not a slogan, but relying on each generation of xemc people to make fine technology and hard products." This is the original intention of the coil manufacturing technical team. In the future, this hard-core team will continue to deepen the technological innovation of coils, provide high-quality power solutions for global customers with higher precision and stronger reliability, and let "xemc Intelligent Manufacturing" shine in more key fields.
