But it is known that the hunting occurs by machine parameters or driving conditions. The hunting is a phenomenon that rotor has cyclical oscillation at the center of synchronous speed. That has bad effect on the source and that machine. In the worst case, that machine pulls out and comes to standstill.\\nIn this paper, we solve the rotor dynamical equations of synchronous machine by harmonic balance method. Using Lyapunov method, we investigate the effect of machine parameters on the hunting oscillation of the motor.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学工学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/5474"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0389-102X"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN0025048X"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学工学部紀要"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1993-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"45","bibliographicPageEnd":"68","bibliographicPageStart":"49"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"No45p49.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2003807/files/No45p49.pdf"},"version_id":"2ee65bbd-edd1-4ad8-bc5a-28b21cfbf238"}]},"item_title":"同期電動機の乱調振動現象の解析","item_type_id":"15","owner":"1","path":["1642837867646","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-03-31"},"publish_date":"2008-03-31","publish_status":"0","recid":"2003807","relation_version_is_last":true,"title":["同期電動機の乱調振動現象の解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T01:44:28.760168+00:00"}
