Methodology for the Implementation of a Consistent Information Model for the Electric Drives Production

As a consequence of the global effort against climate change, sales of electrified mobility systems are expected to increase within this decade. Therefore, a transformation of the established automotive production chain is needed in both: manufacturing equipment and control. Despite higher power density and efficiency of electric traction motors, the production must be as cost-efficient as possible assuming highest quality. However, volatile markets as well as economic and legal boundary conditions lead to a high degree of uncertainty with regard to the expected number of units and technologies.In order to be able to respond to these challenges in production by means of adaptability and scalability digitalization is essential. Within this scope, consistency in information transfer and processing need to be ensured across different levels: machine, process and product. Therefore, a standardized and consistent information model needs to be developed and implemented. This information model agrees on the different characteristics of a digital twin and thus enables an application-oriented adaptation of the manufacturing process paths. A scalable control system is integrated as the central intelligence. By using uniform communication protocols on a data platform, the control and management system ensures a resource- and manufacturing-optimized production of electric traction motors.
