It is based on high resolution - high speed 2D mapping of the magnetic field distribution, using a patented semiconductor chip with an integrated 2D array of over 16000 microscopic Hall sensors. The measured magnetic field maps are analyzed by powerful data analysis software which uses advanced algorithms to extract unprecedented magnet information from the MagCam measurements. All these quantitative magnet properties can be tested against user-defined quality tolerances for immediate and automated pass/fail or classification analyses, all in real time. The system can be remotely operated using standard industrial communication protocols for integration in production lines. Its applications include inspection of incoming magnets, automated inline magnet quality control and research and development of magnets and magnetic systems and more.","PeriodicalId":333533,"journal":{"name":"2011 1st International Electric Drives Production Conference","volume":"2001 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133030445","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 small size, a high protection class, low fuel consumption and a safe operation are basic requirements, which have to be met in order to design successful solutions. A complete drive system, consisting of a highly efficient permanent magnet synchronous machine with integrated inverter and an effective cooling system, safety- and energy storage devices, was developed in order to fulfill these demands. It is a very compact propulsion system, which could be easily integrated into different existing vehicle concepts. It is already implemented in vehicles and operated in continuous field tests in the full speed and power range. The system proved its effectiveness even in extreme temperature conditions.","PeriodicalId":333533,"journal":{"name":"2011 1st International Electric Drives Production Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125819744","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 method is particularly suitable for rotors that run close below or above the first bending critical speed, because a single-sided rotor core eccentricity excites this first bending mode very strongly. This simulation method can be used to optimize the rotor design to avoid elastic balancing. Rigid balancing can be used, even if the rotor runs above the first critical bending speed. Additionally, this method helps to find the tolerable residual unbalance and maximum tolerable limit for a single-sided rotor core eccentricity. Therefore the method helps to optimize the production process by avoiding elastic balancing and machining of the rotor core outer diameter.","PeriodicalId":333533,"journal":{"name":"2011 1st International Electric Drives Production Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121817929","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}

For precise modeling and control, the change in the parameters has to be considered by means of look-up tables. To parameterize these look-up tables, the inductances and the stator resistance have to be identified for various current set points. However, iron losses interfere with a precise identification if they are not considered. Therefore, an extended model is introduced to derive an identification method that considers and compensates for these effects. Measurement results prove the effectiveness of the proposed method.","PeriodicalId":333533,"journal":{"name":"2011 1st International Electric Drives Production Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115575231","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 manuscript presents a part of an ongoing research project which is motivated towards building a prototype of an industrial 7.5 hp IAPMSM. Firstly, a new analytical approach to model the IAMPSM using rotor reference frame theory is proposed. The developed 7.5 hp IAPMSM model is then analyzed through calculated results and compared with the conventional model of the aluminum-rotor induction machine (ARIM) to elicit merits and demerits of the prototype being built. This paper aims to provide a comprehensive understanding of both the machines to serve as a guideline towards prototype development.","PeriodicalId":333533,"journal":{"name":"2011 1st International Electric Drives Production Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115850979","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}
