“…Finally, the proposed technique is different from the previous published works [8,13,21,22], where, a robust sensorless control scheme based on sliding mode observer under short circuit fault between turns is designed in this paper. The proposed technique is based mainly on the measured stator voltage and current, which ensures more simplification, thus the proposed technique can be easily realized.…”

“…Also, it should be noted that the majority of the failures result from crash of winding insulation. The gradual deterioration process of the stator winding insulation is caused by a combination of thermal stresses (aging, overloading and cycling), mechanical stresses (coil movement and strikes from the rotor), electrical stresses and contamination [6][7][8].…”

“…This fault cause a large circulating fault current in the shorted turns of the stator winding, leading to excessive heat generation in the shorted turns. This further degrades the insulation, and finally results to rapidly progress to more severe faults such as lineto-ground or line-to-line faults [8]. A detailed analysis of these types of fault can be found from Kwak's research [9].…”

Open-End Winding Five-Phase Induction Motors (OEW-FPIM) can offer high degree of faults tolerance, reduced common-mode voltage and high torque density. These motors are placed in varying environments and conditions that ultimately reduces the motor efficiency and later leads to failure. This paper proposes a fault-tolerant sensorless sliding mode control based on a parameters estimation (stator resistance, stator inductance and mutual inductance between the stator phases and the rotor phases) of OEW-FPIM with the ability to run the system disturbance-free before and after a short circuit fault between turns. The proposed estimation scheme is intended to improve the system performance even in the fault condition. In addition, a sliding mode observer (SMO) is used to estimate the rotor speed. The simulation results of the proposed sensorless control under a short circuit fault between turns, wherein we demonstrate the effectiveness of the proposed strategy.

“…However, an unexpected fault may occur due to improper operation. According to statistics from [16], among all types of faults, an open-phase or brokenphase of machines, short-circuiting of stator windings [17] and damage to switching devices in the five-phase bridge inverter are the most common. In FPIM with one phase open, when open-circuit fault occurs, a unbalanced currents are generated, which increases the induced torque ripple [18] and distorts the air gap flux distribution causing eventual motor breakdown [19].…”

Five-phase fault-tolerant induction motor (FPIM) with open-end winding (OEW) can offer low torque ripple and it has a merit of high fault-tolerant capability due to its large number of phases. In order to improve the operation performance under an open singlephase. This paper proposes a Remedial Backstepping Control (RBSC) technique for a FPIM-OEW with the ability to run the system before and after fault condition. Hence, the FPIM-OEW losses are decreased, which improves the overall machine efficiency. The proposed RBSC technique lies in the orthogonal reduced-order transformation matrix, which is derived from the fault-tolerant current references, and a new zero-sequence current related to torque ripple. Also, the effect of the open-phase fault on the motor model under the transformation matrix is discussed. The simulation results of the proposed technique under open single-phase are provided, wherein we demonstrate the effectiveness of the proposed strategy with a fast dynamic and steady-state performances as that under healthy operation.

Purpose The impact of the loop current (LC) on the motor magnetic field in the analysis of the inter-turn short circuit (ITSC) fault is always ignored. This paper made a comparative study on the electromagnetic field of permanent magnet synchronous motors (PMSM). The purpose of this study is to explore the necessary of the LC existing in the fault analysis and the electromagnetic characteristics of the PMSM with the ITSC fault when taking into account the LC. Design/methodology/approach Based on the finite element method (FEM), the fault model was established, and the magnetic density of the fault condition was analyzed. The induced electromotive force (EMF) and the LC of the short circuit ring were studied. The three-phase induced EMF and the unbalance of the three-phase current under the fault condition were studied. Finally, a prototype test platform was built to obtain the data of the fault. Findings The influence of the fault on the magnetic density was obtained. The current phase lag when the ITSC fault occurs causes the magnetic enhancement of the armature reaction. The mechanism that LC hinders the flux change was revealed. The influence of the fault on the three-phase-induced EMF symmetry, the three-phase current balance and the loss was obtained. Originality/value The value of the LC in the short circuit ring and the influence of it on the motor electromagnetic field were obtained. On the basis of the electromagnetic field calculation model, the sensitivity of the LC to the magnetic density, induced EMF, current and loss were analyzed.
