Therefore, the axial gap motor has the advantage of being small size and lightweight because its high efficiency leads to high power density. The authors are researching an electric pump rocket engine, which has a simpler configuration than the conventional turbopump rocket engine. It is expected that the engine system will become simpler and lighter by applying it. Therefore, we have extracted the technical issues and conducted technical studies on the application. One of the technical problems is that the axial gap motor has a gap between the rotor and the stator in the axial direction, so the influence on the motor torque when the gap changes. This JAXA-RM focused analytically on the torque behavior when axial displacement of the motor occurs. As a result, it was found that the motor torque does not change greatly with the displacement of the bearing system movement assumed in the bearing.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA2230015000","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: JAXA-RM-22-004","subitem_description_type":"Other"}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20637/00049027","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2224","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構研究開発部門第四研究ユニット(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構研究開発部門第四研究ユニット(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構研究開発部門第四研究ユニット(JAXA)"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Research Unit Ⅳ, Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Research Unit Ⅳ, Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Research Unit Ⅳ, Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_version_type_30":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"島垣, 満"}],"nameIdentifiers":[{"nameIdentifier":"553339","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"木村, 俊哉"}],"nameIdentifiers":[{"nameIdentifier":"553340","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"髙田, 仁志"}],"nameIdentifiers":[{"nameIdentifier":"553341","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SHIMAGAKI, Mitsuru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"553342","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KIMURA, Toshiya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"553343","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TAKADA, Satoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"553344","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":"2023-01-20"}],"displaytype":"detail","filename":"AA2230015000.pdf","filesize":[{"value":"3.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA2230015000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/49044/files/AA2230015000.pdf"},"version_id":"1824e555-f52f-46c3-b2c7-76d1542869a8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Axial flux motor","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Single-shaft electric pump","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Liquid Rocket Engine","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"アキシャルギャップモータによる液体ロケットエンジン電動ポンプへの可能性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"アキシャルギャップモータによる液体ロケットエンジン電動ポンプへの可能性"}]},"item_type_id":"3","owner":"1","path":["1893","2237"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-01-20"},"publish_date":"2023-01-20","publish_status":"0","recid":"49044","relation_version_is_last":true,"title":["アキシャルギャップモータによる液体ロケットエンジン電動ポンプへの可能性"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T18:44:23.864514+00:00"}
