Abstract: With the rapid development of the new energy vehicle industry, as a core component of the drive motor system, the training of its disassembly, assembly and maintenance skills is particularly important. However, training in the disassembly and maintenance of drive motor systems generally faces prominent issues such as high susceptibility to damage of precision parts, limited practical training space, difficulty in disassembling and assembling complex components, and restrictions on training scale. To address these challenges, this article takes the Volkswagen ID.4 CROZZ drive motor system as the research object. The three-dimensional model construction and optimization of the drive motor are completed through Blender, and the model is imported into the Unity3D platform to design and develop the virtual assembly system of the drive motor. The model is then imported into the Unity3D platform to design and develop a virtual assembly system for the drive motor. This system not only provides cognitive learning of component structures but also supports interactive manual disassembly and assembly operations of the motor drive system. It intuitively demonstrates the core structure and assembly process of the motor, significantly enhancing users' understanding and operational skills. This virtual system helps overcome the limitations of traditional training models in terms of resources, space and efficiency, providing innovative technical support for the cultivation of technical talents related to new energy vehicles.
