The induction motor operating reliability is a major issue of modern industry since faults may occur and disrupt the production process. In this work, the diagnostic potential of the line or phase current frequency spectrum for the identification of the broken bar fault in the cage induction motor is investigated depending on the stator three-phase winding configuration. The work is carried out with transient finite element method (FEM) simulations considering motor operation under nominal mechanical load. The study will concern the traditional broken bar fault signatures but also higher order harmonics and will lead to a comparison between their reliability to detect the broken bar fault, with respect to prior work.

The influence of the semimagnetic stator wedges of different sizes on the electromagnetic characteristics and the behavior of the induction motor is investigated. The study will be carried out with both analytical calculations and FEM analysis. The analytical calculations will take into account the stator and rotor slots, as well as the iron core saturation in order to study the spatial and time-dependent harmonic content of the air-gap magnetic flux density and electromagnetic torque. The size of the wedge plays an important role as it determines the tooth tips saturation, the high harmonic content of the air-gap magnetic flux density, and the electromagnetic characteristics of the induction motor.
