“…These faults can be classified according to their location: stator faults and rotor faults. Various surveys on motor reliability have been carried out over the years [15,16], these surveys indicate that the failure percentages of various components in motors are: bearing (41 %), Stator winding (37 %), rotor faults (Broken rotor bars and end ring faults) (10 %) and others (12 %), depending on the type and size of the machine [17]. It can also be seen that the stator faults are one of the most common faults in motors and are caused by stator insulation breakdown [18], which leads to short circuit between turns.…”

Open-end winding induction machines are gaining more attention in the last years due to their attractive advantages in the industrial applications, where high reliability is required. However, despite their inherit robustness, they are subjected to various electrical or mechanical faults that can ultimately reduce the motor efficiency and later leads to full failure. This paper proposes a method of modeling the five phase induction machine with open end stator winding taking into consideration the short-circuit fault between turns.The fault modeling is based on the theory of electromagnetic coupling of electrical circuits. In addition, a sliding mode observer is used to estimate the speed rotor. The idea of proposed backstepping strategy is used in this paper to allow to the studied machine to continue its operating state under short circuit fault between turns. The proposed sensorless control strategy is evaluated in terms of the healthy and faulty performances through the simulation results presented in this paper. The obtained results prove that the proposed sensorless control technique allows to the open-end winding five phase induction machine to continue its operation mode under the specified fault of partial short-circuit of the stator winding. This can be a very practical situation in the industrial applications, especially in the case where the maintenance is not easy and the operation of the industrial process should not be interrupted suddenly.
