The instantaneous torque of the induction motor pulsates with six times the fundamental frequency in the sine-wave PWM system as compared to the fundamental sine-wave signals with a triangular carrier signal. This phenomenon is similar to an optimal PWM system using a sine-wave pattern. This pulsation is based upon a voltage vector pattern. A 6th harmonic signal of fundamental frequency is added to sine-wave signals of the sine-wave PWM system, in order to eliminate this pulsation. The instantaneous torque and current of the induction motor were computed by the state variable method. As a result of computation, the 6th harmonic pulsation of torque vanishes as compared with the sine-wave PWM system, or the optimal PWM system. In the same manner as the sine-wave PWM system, however, the inner small ripple remains in the waveform. It does not appear in the optimal PWM system. On the other hand, such a waveform as an instantaneous maximum torque constant is shown by the use of a modification of the optimal pattern. In this case, the bottom of the torque waveform varies by six times to the fundamental frequency. The motor current is a sinusoidal waveform as is the sine-wave PWM system in all the patterns.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0451212X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040363","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"542","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"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":"実成, 義孝","creatorNameLang":"ja"},{"creatorName":"MINARI, Yoshitaka","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"篠原, 勝次","creatorNameLang":"ja"},{"creatorName":"SHINOHARA, Katsuji","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"福元, 木草","creatorNameLang":"ja"},{"creatorName":"FUKUMOTO, Mokuso","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"入佐, 俊幸","creatorNameLang":"ja"},{"creatorName":"IRISA, Toshiyuki","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"AN00040363_v31_p45-51.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040363_v31_p45-51.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/10601/files/AN00040363_v31_p45-51.pdf"},"version_id":"3a98ced0-fc85-4f6a-aa51-6b1976d4cdd9"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"電圧形インバータ駆動誘導電動機のトルク脈動低減PWM制御法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"電圧形インバータ駆動誘導電動機のトルク脈動低減PWM制御法","subitem_title_language":"ja"},{"subitem_title":"PWM method for reduction of torque pulsations of an induction motor driven by voltage source inverter","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["36","5351"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-04"},"publish_date":"2015-06-04","publish_status":"0","recid":"10601","relation_version_is_last":true,"title":["電圧形インバータ駆動誘導電動機のトルク脈動低減PWM制御法"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-20T05:02:50.756358+00:00"}
