“…To ensure current sharing and low current harmonics, Oguchi presented a novel six-phase inverter system in which 60-step output voltages were generated [15] . Several authors have addressed the issue of fault tolerance, focusing for the large part on the behavior and compensation strategies of machines in which a single phase is open circuited and on for opencircuit faults [16][17][18] .…”

Stator current sharing will be unbalance in dual three-phase permanent-magnet synchronous motor (DTP-PMSM) drives since two three-phase systems have inherent asymmetries. In this paper, a simple current sharing scheme is proposed to eliminate the inherent asymmetries of the two threephase systems. It will enable the motor to operate with balance current sharing between the two three-phase winding sets and has low implementation complexity. The control scheme is validated by simulation and experiment with a 3kW DTP-PMSM drive prototype.

The operation of ac drives in applications requiring high overload capability imposes hard working conditions on the electronic switching devices. The use of induction motors with two stator windings, fed by two inverter modules, allows large power rating in variable speed drives for high performance applications. This paper shows the structure and the main features of a fieldoriented control for a double winding motor, fed by two GTO inverters.The operational results of a 850 kW drive, working as a melt pump in a polyethylene plant, are reported in order to describe the obtained performances.

“…Modeling and control of induction machines in faulty situations have been topic of many studies [1][2][3][4][5]. Zhao and Lipo have carried out research on faulty multi-phase IM where one of the stator phase is cut off [1]. Abbaszadeh et al presented a method for modeling and control of dual 3-phase IM when two stator phase are cutoff [2].…”

“…Additionally, modeling and control of faulty or unbalanced IM can be extended to single-phase IM vector control since single-phase IM with different main and auxiliary windings is an unbalanced IM. Modeling and control of induction machines in faulty situations have been topic of many studies [1][2][3][4][5]. Zhao and Lipo have carried out research on faulty multi-phase IM where one of the stator phase is cut off [1].…”

This research discusses d-q model and Rotor FluxOriented Control (RFOC) technique for faulty three-phase Induction Motor (three-phase IM when one of the stator phases is opened). In the controlling technique, two transformation matrixes are applied to the equations of faulty three-phase IM. As a result, the equations of faulty three-phase IM become similar to the balanced IM. Therefore, by employing some modifications in the conventional block diagram of the balanced IM, faulty motor control is possible. Additionally, for high performance vector control of the faulty IM, an Extended Kalman Filter (EKF) is used for motor speed estimation. Simulation results demonstrate the validity and applicability of this technique to improve performance of the faulty IM.
