Implementation and verification of the Amplitude Recovery Method algorithm with the faults diagnostic system on induction motors

The implementation and verification of the amplitude recovery method algorithm (A.R.M.), which was first presented in ICEMS2008, are displayed in this paper. The mathematics deduction, application and test results show that the A.R.M. can extract directly the energy of the harmonics of other orders (including high orders and fractional orders) in the tested original signals of three phase stator currents of induction motors even though the harmonics elements are much smaller than the fundamental one.
