Lately, a new diagnostic mean has been introduced for reliable fault diagnosis in delta-connected induction motors. This diagnostic mean is the zero-sequence current frequency spectrum. Since this diagnostic mean successfully answers to a variety of reliability demands, a thorough investigation of its harmonic index has to be performed as a function of the rotor geometry. In this work, FEM sinulations have been performed for motors of different rotor slot numbers and the zero-sequence current spectra are studied with the application of the FFT. Finally, experimental testing is applied to verify the simulations results.
