Modeling and Diagnostic of Incipient Inter-Turn Faults for a Three Phase Permanent Magnet Synchronous Motor Using Wavelet Transform

Inter-turn faults in the stator winding of PMSM is one of the major cause of motor failure. Therefore prevention and early detection of fault occurrence are crucial in the industrial field. End winding turns can suffer from mechanical vibration due to electromagnetic efforts. With aging, end winding blocking systems become weaker and turns insulation degrades until its breakdown. In this paper, a modeling and a detection method for intermittent …
