A Novel Method for IRFOC of Three-Phase Induction Motor under Open-Phase Fault

Abstract

This paper investigates the vector control of a star-connected three-phase Induction Motor (IM) under stator winding open-phase fault. The used vector control method is based upon indirect rotor field-orientation concepts that have been adapted for this type of machine. Beside the implementation of this method in critical industrial applications, the proposed method in this paper can be used for vector control of unbalanced 2-phase or single-phase IM with two main and auxiliary windings. Simulation results are provided to show the operation of the proposed drive system. Keyword:Field

An Experimental Investigation of Heating in Induction Motor under Open Phase Fault

“…The attention is paid to the waveforms of the currents in individual stator phases, the increase in torque pulsations and the decrease of speed in emergency operation after the disconnection of a faulty phase of the source. In reference [13], the authors investigated the vector control of a star-connected three-phase induction motor under the stator winding open-phase fault. In references [14], [15], the authors deal with the modeling of a three-phase induction motor under open-phase fault using the Matlab/Simulink implementation.…”

“…So, we can note that the results obtained from this study are as expected because in our case the windings are coupled in delta configuration and in the presence of this defect, we will have two windings having the same current, in parallel with the third winding. On the other hand, in the researches [13][14][15], the authors deal with the modeling of the star-connected three-phase induction motor. However, the presence of the open phase fault in the star coupling, leads to a loss of the phase, which leads to a complete loss of the coil (I = 0 A).…”

“…Among [13]. It was recommended in [10], using suitable transformation matrices it is possible to remove the unsymmetrical structure of a 3-phase IM under open-circuit fault.…”

Comparison and assessment of a different steel materials based on core losses reduction for three-phase induction motor

“…During the recent years, the induction motors (IM) are utilized, instead of the DC motors, in many different applications including domestic and industrial uses such as heat pumps, wind generator, textile mills, machine tools, transposition, air conditioners, and robotics [1]- [4]. In order to make the induction motors operate, there is no need for sliding contacts or permanent magnets, which make them too simple and have low manufacturing cost [5]- [8].…”
