Speed sensorless vector control of 3-phase induction motor under open-phase fault (faulty 3phase induction motor) based on Indirect Rotor Field-Oriented Control (IRFOC) is proposed in this paper. To ensure high performance FOC of induction motor drives, the estimation of the rotor speed is necessary. However, the algorithm used to estimate the rotor speed for a 3-phase induction motor cannot be...

rotating machines in particular induction electrical machines are important industry instruments. in manufacturing, electrical motors are exposed to many damages, and this causes stators and rotors not to work correctly. in this paper we addressed modal analysis and an intelligent method to detect motor load condition and also the stator faults such as turn-to-turn and coil-to-coil faults using...

The area of multiphase variable-speed motor drives in general and multiphase induction motor drives in particular has experienced a substantial growth since the beginning of this century. Research has been conducted worldwide and numerous interesting developments have been reported in the literature. An attempt is made to provide a detailed overview of the current state-of-the-art in this area....

induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. speed identification is needed for the induction motor drives. however, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. ther...

Accurate rotor time constant ( $T_{r}$ ) value is necessary to ensure an acceptable performance of the indirect field-oriented control (IFOC) strategy, where a detuned affects flux orientation and, in turn, results poor dynamic and st...

In view of the attractive features like improved torque density, reduction pulsation, superior fault tolerance, reduced power rating voltage source converter, and sterling noise characteristics six-phase asymmetrical induction motor (SPAIM) as compared to its three-phase counterpart, SPAIM is considered for study. this paper, mathematical modelling carried out in synchronous reference frame the...

Multiphase machines are becoming one of the mainstream research topics during last decade, especially in high-reliability based systems. Among different configurations multiphase machines, Asymmetrical Six-Phase Induction Motor (ASPIM) with a spatial displacement 30° is popular as it has better magnetomotive force (MMF) distribution. This paper therefore concerns detecting and mitigating operat...
