The diagnosis exploits the signal delivered by the two sensors placed in particular positions. Contrary to classical methods using only one sensor, the presented method does not require any knowledge of a presumed machine\u2019s healthy former state. On the other hand, the loading operating is not a disturbing factor but it is used to the fault discrimination. In order to present this procedure, an internal stator inter-turn short-circuit fault is considered as well.<\/jats:p>","DOI":"10.3390\/s101110448","type":"journal-article","created":{"date-parts":[[2010,11,18]],"date-time":"2010-11-18T11:53:33Z","timestamp":1290081213000},"page":"10448-10466","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["An Online Universal Diagnosis Procedure Using Two External Flux Sensors Applied to the AC Electrical Rotating Machines"],"prefix":"10.3390","volume":"10","author":[{"given":"Remus","family":"Pusca","sequence":"first","affiliation":[{"name":"Univ Lille Nord de France, F-59000 Lille, France"},{"name":"LSEE, Facult\u00e9 des Sciences Appliqu\u00e9es, technoparc futura, 62400 Bethune, France"}]},{"given":"Raphael","family":"Romary","sequence":"additional","affiliation":[{"name":"Univ Lille Nord de France, F-59000 Lille, France"},{"name":"LSEE, Facult\u00e9 des Sciences Appliqu\u00e9es, technoparc futura, 62400 Bethune, France"}]},{"given":"Andrian","family":"Ceban","sequence":"additional","affiliation":[{"name":"Univ Lille Nord de France, F-59000 Lille, France"},{"name":"LSEE, Facult\u00e9 des Sciences Appliqu\u00e9es, technoparc futura, 62400 Bethune, France"}]},{"given":"Jean-Fran\u00e7ois","family":"Brudny","sequence":"additional","affiliation":[{"name":"Univ Lille Nord de France, F-59000 Lille, France"},{"name":"LSEE, Facult\u00e9 des Sciences Appliqu\u00e9es, technoparc futura, 62400 Bethune, France"}]}],"member":"1968","published-online":{"date-parts":[[2010,11,18]]},"reference":[{"key":"ref_1","unstructured":"Scheffer, C, and Girdhar, P (2004).
