For a cost efficient production of electrical engines, in first-class quality and in sufficient quantity, it is indispensable to understand the process of coil winding. Thereby the prediction of the wire behavior is one of the key challenges. Therefore, a detailed model is built to investigate wire behavior during the linear winding process. The finite element based simulation tool LS-DYNA serves as explicit dynamics tool. To represent the high dynamic process of winding within this simulation, some first adaptions have to be made. This means, that dynamic influences such as rotational speed or acceleration of the coil body are definable. Within process simulation, the given boundary conditions are applied to the model. The material properties of the wire under scrutiny are validated by a tensile test and by the values out of datasheets in previous research. In order to achieve the best convergence, different contact algorithms are selected for each individual contact behavior. Furthermore, specific adjustments to the mesh are necessary to gain significant results. State of the art in coil winding is an experimental procedure, which delivers adequate process parameters and, thus, expertise in winding technology. Nevertheless, there are a lot of different, interacting parameters, which have to be optimized in terms of boundary conditions. The simulation model of winding process, in which varying parameters can be optimized pertaining to the optimal winding result, calls for extensive research in this field. The generated model enables the user not only to influence the process parameters but also to modify the geometry of a winding body. To make the simulation scientifically sound, it is validated by previous experiments and simulations","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129875415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In spite of these increasing challenges consumers are not willing to pay for risen efforts. Industry relies on effective and efficient management and coordination of the departments involved across company and supply chain during all phases of product and process development. Modular Production Architectures (MPA) are a useful management-tool for the upcoming difficulties during product and process development. Especially, MPA can contribute to dissolve the contradiction between standardization and innovation. In this paper current standardization approaches are presented, i.e. general modular product architectures and process construction kits. MPA are then derived from the existing models as a standardization approach for the product-process-link. The methodology is described using a three step approach. Firstly, the product type range and the production steps have to be determined. Subsequently, the best-practice is to be identified by comparing different alternatives or benchmarking across competitors. In the last step the product design boundary parameters have to be implemented in the whole process chain. The paper is terminated by a validation of the presented approach in automotive industry.","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125460173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is well known that the shape of the electromagnetic forces acting along the circumference of the stator core is decisive for the generation of noise and vibration. The influence of the axial behavior of these forces is, however, to a great extend unexplored. A first insight is gained in this paper by means of a structural dynamic response analysis of a stator for different skewing sequences. Each sequence excites a particular combination of structural modes differing in their axial behavior. Structural modes of a low axial order have shown to be significantly more relevant concerning the acoustic behavior of a machine. Therefore, an analytic method is developed that allows a comparison of different skewing arrangements regarding the excitation axial modes without the necessity of structural FE simulations. A comparison of three particular skewing arrangements (linear, v-shaped, and zigzag predicts a significant influence on the vibro-acoustic behavior. To validate the results, three prototype traction machines have been built. The measurement results follow the predicted influence with differences in the sound pressure level of more than 10dB.","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133799775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
