Already H.E .Edgerton has given formulae for critical conditions of the pulling-into-step by the differential analyzer. But these formulae are not accurate enough. Then using a phase plane method, this paper dealt sufficiently with the effect of saliency, and calculated the conditions exactly by dint of a digital computer. Consequently, we obtained the conclusion that the phase plane equations are classified into two cases according to the relatability of the coefficients ; i.e. a whether a limit cycle exists or not. When a limit cycle exists in a phase plane, the longitudinal mean value is equal to the value of the rate of \u03b2 to \u03ba. In addition, the relations of \u03b2 to critical \u03ba under the condition where b and g are parameters, are as follows : 1) The curve of it is illustrated by the saturated one, which is considerahly different from the Edgerton\u2019s curve. 2) The influence of g upon the curve is larger, that of b is smaller. Where, \u03b2:\u3000load ratio;\u3000\u03ba: relative damping coefficient; b: pulsation factor due to saliency;\u3000g: reluctance torque ratio.", "subitem_description_type": "Abstract"}]}, "item_2_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "31746", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ikuo, TAKEDA"}]}, {"nameIdentifiers": [{"nameIdentifier": "31747", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Goro, MIURA"}]}]}, "item_2_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u5317\u898b\u5de5\u696d\u5927\u5b66"}]}, "item_2_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u6b66\u7530, \u90c1\u592b"}], "nameIdentifiers": [{"nameIdentifier": "31744", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u4e09\u6d66, \u4e94\u90ce"}], "nameIdentifiers": [{"nameIdentifier": "31745", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "2-2-2.pdf", "filesize": [{"value": "7.8 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 7800000.0, "url": {"label": "2-2-2.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/6201/files/2-2-2.pdf"}, "version_id": "5f845702-d2d7-4785-bf23-f4c7deabd33f"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "\u540c\u671f\u96fb\u52d5\u6a5f\u306e\u540c\u671f\u5316\u73fe\u8c61\u306b\u95a2\u3059\u308b\u7814\u7a76 \uff08\u7b2c\uff11\u5831\uff09", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u540c\u671f\u96fb\u52d5\u6a5f\u306e\u540c\u671f\u5316\u73fe\u8c61\u306b\u95a2\u3059\u308b\u7814\u7a76 \uff08\u7b2c\uff11\u5831\uff09"}]}, "item_type_id": "2", "owner": "1", "path": ["7/15/22"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/6201", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2007-04-09"}, "publish_date": "2007-04-09", "publish_status": "0", "recid": "6201", "relation": {}, "relation_version_is_last": true, "title": ["\u540c\u671f\u96fb\u52d5\u6a5f\u306e\u540c\u671f\u5316\u73fe\u8c61\u306b\u95a2\u3059\u308b\u7814\u7a76 \uff08\u7b2c\uff11\u5831\uff09"], "weko_shared_id": 3}
