| Abstract: | With the analysis of characteristic of cage induction machines under light load and start-up,this paper analyzed the fault features of rotor bar breaking,and a series of novel detection schemes are presented.That focuses on the early detection of the winding faults in asynchronous motors,as would help avoid catastrophic failure,reduce repair cost and outage time to a great extent. |
