But mostly, this idea to reduce the energy consumption is being implemented after the manufacturing technologies are installed. However, it would be more advantageous if efforts were made to save energy during the early planning process. To achieve an estimation of the energy consumption in this early planning stage, a new suitable forecast method is required. Therefore, this paper shows how the prospective energy consumption can be determined by using Methods-Energy Measurement (MEM). Based on the needs of production planners, future challenges and requirements for MEM are listed. Further-more, the concept of basic energy elements and their value determination techniques are introduced, and different possibilities are outlined and assessed. For an easier determination of the energy demands of a complex production cell or manufacturing equipment, standard equipment patterns will be designed. This template supports both planners and decision-makers to create reliable and standardized Resource Performance Indicators (RPI). Subsequently, the architecture of the MEM-calculation model is presented. This approach enables a holistic estimation of the energy consumption of manufacturing technologies and leads to higher levels of transparency. Furthermore, MEM contributes to identify and realize sustainable solutions in advance and as a result, increases the profitability of a factory.","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"5 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":"115354648","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}

However, frequency dependent losses of litz wires and solid conductors differ strongly. In this paper, a coupled process of numerical simulation and analytical methods is described which allows efficient simulation of full 3D structures including resolving litz wire sub-structure. To achieve this, 3D simulation with a simplified conductor calculates the magnetic field in the entire system. Based on these data, a new analytical method determines the losses in the litz wire along the conductor for the large number of 2D cross-sections. The error of the analytical method is less than 5% at frequencies up to 1MHz and external magnetic fields up to 2500kA/m. Because of the significant reduction of calculation time, windings and ferrite structures can be efficienly optimized.","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"29 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":"115199223","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}

Due to their excellent isolating characteristics, electrical sheets that are coated with baked varnish are often considered to be electric benchmarks. Besides a pure loss evaluation of the laminated stacks, a cost reduction of the overall system should also be aimed for. This paper deals with the optimization of a real production line and focuses on the process chain: stamping with subsequent baking of single-tooth stator stacks for automotive application. The main focus of the improvement potential lies on the baking process, including the necessary pre- and post-processing. In order to optimize the existing line, the simulation software Tecnomatix Plant Simulation was used. Through bottleneck analyses of the modeled system, targeted improvements were derived to achieve a significant increase of the output. Those simulation studies enable virtual adjustments to the running system and a quantification of the expected effects. In the context of a real example, quantitative improvement potentials are presented and the limitations of the process chain baked varnish stacking are shown.","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"1 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":"114193790","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}

A systematic comparison between hard-and soft-switching topologies, as well as different operating frequencies, is performed and the impacts on system efficiency and complexity are assessed in detail. In a holistic design process each system is individually optimized for a charging power of 3kW and a variable air gap from 100mm to 170mm at a coil diameter of 500mm. It is shown that the hard-switching topologies are highly attractive in the considered power range even with state of the art semiconductors. By introducing a dual-side controlled topology a superior system efficiency is demonstrated at an operating frequency of 35 kHz.","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"17 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":"130766418","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}

The uncertain parameters studied include investment and bill of materials costs as well as cycle time. The resulting influence of these uncertainties are presented for each case individually, as well as all possible combinations, giving seven total cases studied. Cutting tool costs over a range of batch sizes show that investment uncertainty has rapidly declining impact even within fairly low batch sizes. BOM cost variations, especially for the permanent magnets maintain a sizeable influence over the range of batch sizes. The Weibull distribution based model for permanent magnet insertion shows that profit margins derived from point based nominal data is not reliable for pricing of manual production processes. The presented approach is useful both for decision making regarding new production, as well as pricing in competitive markets with narrow margins.","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"10 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":"117133881","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}

The particular application determines the requirements regarding the properties of multipolar magnets, as for example the accuracy of the pole pitch. The injection molding process of polymer bonded magnets allows a cost efficient production of complex design of the magnets' shape and its magnetizing structure. The final properties of injection molded magnets are influenced by the magnetic compound, the injection mold design and thus, the magnetic field in the cavity, as well as the process parameters. This paper deals with the design and production of multipolar magnets in the injection molding process. In a first step an overview of the requirements of multipolar magnets in different applications is given and important characteristic parameters are identified. In a second step the influences during the manufacturing process on the important characteristic properties of multipolar magnets are evaluated.

In particular for high frequency applications, such as automotive traction, thin electrical steels are used to reduce the eddy current losses, so the surface related effects become relatively more important and their proper control can bring a relevant performance enhancement.

Therefore, they are suitable for direct drives if challenges like high torque ripple and complex mechanical design of the soft magnetic part are solved. High torque ripple can be reduced by an intelligent feedback control system. As far as mechanical design is concerned, a lot of papers deal with different topologies of transverse flux machines' magnetic circuits, but many of these topologies are difficult to manufacture. Papers dealing with topologies which are easy to manufacture are rare. This paper presents a lamination concept and the construction process of a permanent magnetic excited transverse flux machine.

There is also an enormous impact on the development of auxiliary devices. So far it was common to use small DC-motors as actuator for the low power applications such as window openers, seat adjusters or ventilators. Meanwhile, also influenced by the ongoing discussion to increase the on-board voltage to 48 V, even former belt driven auxiliary devices with high energy consumption are being replaced by highly optimized mechatronic modules driven by BLDC-motors. Since these components are produced in a large volume and have to fulfill severe requirements regarding product performance, manufacturability and cost, a multi-domain optimization on system level is important.
