Effects of the simultaneous presence of static eccentricity and broken rotor bars on the stator current of induction machine

A Modified Model of Squirrel Cage Induction Machine Under General Rotor Misalignment Fault

“…Mean radius function depends on the geometry of the air gap. In many studies, this function has been considered to be constant [7,8,[13][14][15][16][17][18][19][20][21][22]. Fig.…”

“…This method was used to calculate the mutual inductance of a three-phase induction machine under static inclined eccentricity condition. Different inclined eccentricities in induction machines have been previously documented [19][20][21][22]. In these models, only static inclined eccentricity is considered.…”

Cage-rotor induction motor inter-turn short circuit fault detection with and without saturation effect by MEC model

“…In [25][26][27] FEM and WFA were applied to study the wound-rotor induction and also synchronous reluctance machines and the PSD of torque and stator currents was used to analyze the machines performance in healthy and faulty conditions neglecting the saturation effect. In [28] the saturation effect of teeth and slot opening effect was considered simultaneously and in [29], broken bar fault has been studied for cage induction machines without slot opening effect. In [30], inductances of induction machines were computed in both healthy and faulty conditions excepting the saturation effect.…”

Slot Numbering and Distributed Winding Effects Analysis on the Torque/Current Spectrum of Three-phase Wound-rotor Induction Machine Using Discrete Modeling Method

“…In [23], the closed-slot effect was studied on electrical machines harmonics, and stator current signatures were studied for cage rotor induction machines in [24]. In [25] the saturation effect was presented for teeth and slot and opening effect was considered, and in [26], which considered slot opening effects, a broken bar fault was researched for cage induction machines. In these works, there is none on the slot numbering effect on the current and torque spectral of wound-rotor induction machines.…”
