Superconductors are promising for developing high-efficiency motors. However, superconducting wires must be kept in critical conditions and the AC loss needs to be minimized. In this paper, a design of a superconducting interior permanent magnet synchronous motor (IPMSM) is proposed that reduces the AC loss. The characteristics of superconducting and normal-conducting IPMSMs are compared. The proposed superconducting IPMSM has a low AC loss and a very high efficiency at low speeds.","PeriodicalId":6398,"journal":{"name":"2012 15th International Conference on Electrical Machines and Systems (ICEMS)","volume":"32 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91205203","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, it is necessary to develop rare-earth-free motors for the HEV traction motors owing to several problems such as price hike and export restriction of rare-earth materials. In this paper, a ferrite permanent magnet axial gap motor with coreless rotor structure is introduced as the rare-earth-free motor. In addition, the motor structure and the results of 3D-FEA are described in detail.","PeriodicalId":6398,"journal":{"name":"2012 15th International Conference on Electrical Machines and Systems (ICEMS)","volume":"151 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77803863","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, case of large system, requires lengthy analysis time, generates many suboptimal solution, and unsatisfactory solutions of energy balance equations are obtained. Objective of this study is to develop a computer algorithm for planning operation of compound energy system with many design parameters with a high accuracy by introducing orthogonal table in GA. Orthogonal table is introduced to reduce operation range that is considered to include optimal operation of compound energy system. By analysis results, orthogonal table-GA hybrid method is a significant improvement over optimization methods that employ to traditional GA, and can be utilized to increase of design parameters and improve of analysis accuracy.","PeriodicalId":6398,"journal":{"name":"2012 15th International Conference on Electrical Machines and Systems (ICEMS)","volume":"8 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72637410","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}
