Approaches which integrate e-machine, power electronics, control, gearing and cooling into a common housing offer high potential for compact and cost efficient (H)EV drivetrains. The transition to distributed multiphase inverter and motor concepts enables a novel level of system integration. A new smart stator tooth concept is presented. It comprises the integration of a segmented stator tooth together with dedicated power electronics and control electronics. This enables new degrees of freedom in terms of motor design, assembly and control.","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"150 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":"133594931","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}

During the manufacturing process of electrical machines, the used enameled wires are exposed to deformations which decrease the insulation resistance against partial discharge and disruptive discharge. A reduced insulation resistance shortens the product lifecycle. The active controllable and flexible winding needle is able to adapt its form to the mechanical behavior of wire during any deformation and thus to wind wires more gently. In the production of electrical machines the copper filling factor in the slot is often considered key. To provide the needed space for the tools to move through the stator while distributing the windings, the winding tools have to be rather small or the inner diameter of the stator has a minimum whereat the feasibility for needle winding is still present. With the actively controllable and flexible winding needle no more extra axis and other constructions are necessary to fulfill the requirements of a small tool at maximum flexibility.","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":"131062427","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}

Annealing of electrical steel 电工钢的退火

{"title":"Annealing of electrical steel","authors":"E. Hilinski, G. H. Johnston","doi":"10.1109/EDPC.2014.6984385","DOIUrl":"https://doi.org/10.1109/EDPC.2014.6984385","url":null,"abstract":"Annealing of electrical steel, while classified as a heat treating operation and subject to conventional CQI-9 audit principles, is almost exactly the opposite of most other heat treating operations. One of the primary reasons for heat treating of steel is to harden or strengthen it via carburizing, nitriding or similar where performance is measured in terms of hardened case depth. Conversely, annealing of electrical steel is designed to remove carbon (decarburizing) from the bulk of the steel with concurrent grain growth and stress relief. For electrical steel the annealing performance is therefore measured in terms of reduction in electrical losses. Data are presented showing that core loss in electrical steel is increased by any form of plastic and elastic stress. Furthermore, core loss is also highly dependent on residual carbon, therefore any additional reduction in carbon beyond that achieved in the manufacturing process utilized by the steel mill, even in the parts per million (ppm) range, further reduces core loss. As a result, annealing can enable significant electrical performance benefits by reducing core loss and exciting current by as much as a steel grade level or more. The chemistry and thermodynamic conditions for the decarburization reaction must be carefully controlled so that decarburization occurs without deleterious subsurface oxidation. Examples are presented for both annealing of semi-processed as well as fully processed electrical steels. Even with highly alloyed, thin electrical steels, that are used in high frequency applications, such as for Hybrid Electric Vehicle (HEV) and Electric Vehicle (EV) motor designs, annealing provides a material performance benefit, but the property improvement is limited to frequencies under 800 Hz, after which thickness and resistivity become the dominant factors in controlling losses.","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"150 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":"122766280","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 compact layout and an optimized system topology allow the realization of rectifier and reactive current compensation with a high efficiency of around 98%. The specific layout takes into account cooling of the resonance capacitors as well as of the rectifier. The automotive environment requires failsafe functionality which is independent of the wireless data transfer to the primary side. The hardware is dimensioned and prepared for realizing an additional secondary side power control. Thus, the optimal electrical working point of the energy transfer can be adjusted and overall system losses can be reduced.","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":"123424943","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}

This paper illustrates the necessity of transformable production technologies regarding a varying and increasing demand of electric drivetrains and explains how to deal with these developments. The paper shows and categorizes the external and internal influences regarding the selection of the right technology for this trendsetting industry. The requirements and important aspects to select an optimal production technology for electric traction motors will be exposed. An efficient selection process supports the manufacturer to choose the best individual technology in a developing market environment.

This paper presents the heat transfer analysis of a modular machine segment with a laminated winding. The laminated winding has a great potential when it comes to production of the winding and the thermal management of the excessive power losses in the winding. The prototype is built and assessed based on experimental measurements and finite element analysis. The results indicate some practical challenges of integrating the combined heat exchanger and winding and controlling the coolant flow through the machine construction. The prototype machine shows a limited enhanced cooling capability mostly due to flow leakage while the results from the simulation models indicate the great potential of direct cooled windings.","PeriodicalId":423456,"journal":{"name":"2014 4th International Electric Drives Production Conference (EDPC)","volume":"67 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":"121745727","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}
