In general, an electromagnetic motor (EMM) has versatility for the output request. In addition, the power of EMM can easily control with the electrical operation. However, the high power EMM has a disadvantage such as response delay by increases of mass and inductance. On the other hand, an ultrasonic motor (USM) has a rapid response by friction force drive between a stator vibrator and a rotor or a slider. If the EMM and the USM are used together in the same actuator system (AS), the individual actuators can complement each other. Then, such AS has a wide output range and high speed response. It is noted that the USM does not have torque free state for an operation by external force. Therefore, realizing such an AS requires high speed clutch/brake.As the first step of study, an ultrasonic AS which was able to electrically control a preload had been developed by combining a USM with a piezoelectric clutch (piezo-clutch). As a result, it was realized that the expansion of the operating range and increased stability, hence a new AS with wide output range and rapid response is realizable by combining the EMM and the ultrasonic AS.The objective of this study is to develop a new hybrid AS that includes an EMM and an ultrasonic AS. In addition, as the one application of wide outputsrange and rapid response, the effect of the force-feedback display by the hybrid AS was considered. The proposed hybrid AS is composed of a USM and an EMM which generate the rotation and a piezo-clutch/brake based on a mechanical amplifier which is used for adjustments of preload and braking force. A preload control by the piezo-clutch was examined. The revolution speed was stabilized by controlled preload using the piezo-clutch. The rise time was shortened by preload control during transient rotation at starting the USM. In addition, the rise time and driving power was reduced by hybrid drive with both of EMM and the USM.As the one application of the hybrid AS, the effect on a force-feedback display was examined. As author’s impression, the hardness feeling was realistically represented by the piezo-brake. The elastic feeling was represented by either the EMM or the USM. In addition, the hybrid AS was extended a two-degree-of-freedom hybrid AS. As a result, the force-feedback was represented with more real operational.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_81_dissertation_number_13":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第355号"}]},"item_81_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15118/00005110","subitem_identifier_reg_type":"JaLC"}]},"item_81_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"547","subitem_subject_scheme":"NDC"}]},"item_81_text_12":{"attribute_name":"学位の種別","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"課程博士"}]},"item_81_text_14":{"attribute_name":"報告番号","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"甲第355号"}]},"item_81_text_15":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"博甲第355号"}]},"item_81_version_type_24":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"桶谷, 涼太","creatorNameLang":"ja"},{"creatorName":"OKEYA, Ryota","creatorNameLang":"en"},{"creatorName":"オケヤ, リョウタ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-15"}],"displaytype":"detail","filename":"A355.pdf","filesize":[{"value":"6.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A355","objectType":"fulltext","url":"https://muroran-it.repo.nii.ac.jp/record/5119/files/A355.pdf"},"version_id":"1f4cd458-af00-4c48-9cb9-fad35250a431"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-15"}],"displaytype":"detail","filename":"A355_summary.pdf","filesize":[{"value":"359.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A355_summary","objectType":"abstract","url":"https://muroran-it.repo.nii.ac.jp/record/5119/files/A355_summary.pdf"},"version_id":"4bcf67ae-3bdf-4058-8099-0690d13ea502"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"圧電ハイブリッドアクチュエータシステムの開発とその応用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"圧電ハイブリッドアクチュエータシステムの開発とその応用","subitem_title_language":"ja"}]},"item_type_id":"81","owner":"18","path":["227"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-06-26"},"publish_date":"2014-06-26","publish_status":"0","recid":"5119","relation_version_is_last":true,"title":["圧電ハイブリッドアクチュエータシステムの開発とその応用"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-11-13T00:29:33.822423+00:00"}
