The author has produced an experimental hysteresis rotor structure in which a ring made of radially-oriented anisotropic magnet material, Alnico 5 which has a large magnetic hysteresis loop, and a yoke made of inner steel are utilized. The prototype hysteresis motor has a large ratio of output power to magnet volume and a large starting torque as compared with conventional hysteresis motors. The author has proposed new rotor structures of synchronous motors (a hysteresis and a permanent-magnet-type synchronous motor) in which rare-earth cobalt magnet pieces are utilized. The prototype synchronous motors have larger ratios of output power to magnet volume than the hysteresis rotor made by radially-oriented anisotoropic Alnico 5. This paper presents the structure, torque analysis, torque characteristics and equivalent circuit of the synchronous condition of the prototype synchronous motors. A comparison of the hysteresis and the permanent-magnet-type synchronous motor is also given.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0656000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-656","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所計測部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Instrumentation and Control Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 博"}],"nameIdentifiers":[{"nameIdentifier":"471921","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YAMADA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"471922","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"naltr00656.pdf","filesize":[{"value":"713.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00656.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44913/files/naltr00656.pdf"},"version_id":"5613355c-b206-4767-b3e8-902f3c8e29c9"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Application of a Rare-Earth Cobalt Magnet to Synchronous Motors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Application of a Rare-Earth Cobalt Magnet to Synchronous Motors","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44913","relation_version_is_last":true,"title":["Application of a Rare-Earth Cobalt Magnet to Synchronous Motors"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:48:37.743882+00:00"}
