Diagnosis of induction machines by d-q and i.s.c. rotor models

Recently both d-q and instantaneous symmetrical components (i.s.c.) models for faulty cage induction machines have been proposed for numerical simulations of stator instantaneous currents. Applying FFT algorithm to stator current the sideband components at frequencies (1-2s)f can be evaluated. The amplitudes of these components are commonly used as… CONTINUE READING
