Precision manufacturing capability is the cornerstone of motor industrialization, and in recent years, motor manufacturing processes have achieved a leapfrog development from manual operation to intelligent factories. In terms of stator manufacturing, Tesla Gigafactory uses high-precision CNC machining centers for stator forming to ensure dimensional accuracy; Joint electronic innovation Ipin and twist head welding technology, optimized flat wire welding process, shortened stator end size; Huichuan Technology uses integrated injection molding technology for stator cores to tightly integrate injection molded components with the stator, further improving slot filling rate. The rotor manufacturing adopts the process of punching adhesive and anchor fixation to ensure structural stability during high-speed rotation. The weaving process and composite material forming technology of carbon fiber rotors are continuously optimized to meet higher speed requirements. ​
The construction of smart factories has accelerated the improvement of manufacturing efficiency, and the Volkswagen MEB platform utilizes mold forming technology to achieve high-precision manufacturing of windings; BYD has established a fully automated production line, with a motor assembly accuracy of ± 0.01mm and a 50% increase in production efficiency. The application of digital technology has achieved full traceability of the production process, real-time monitoring of equipment operation status through IoT technology, and optimization of production scheduling through AI algorithms. Through digital transformation, a certain motor factory has increased its product qualification rate from 98.2% to 99.7%, and reduced unit production costs by 12%. The upgrading of manufacturing processes not only ensures the stability and consistency of motor performance, but also promotes industry scale cost reduction, laying the foundation for the popularization of motor technology.
