“…Multiphase motors, regardless of the type of machine, usually require a more extensive power supply system and more complex control algorithms [1][2][3][4]. Three-phase motors with independent, three-phase dual windings require two independent power supply circuits [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. As a result, two channels are obtained which, depending on the type of machine and the configuration of its windings, may be magnetically independent or partly independent.…”

This article presents the results of a comparative analysis of two electronically commutated brushless direct current machines intended for fault-tolerant drives. Two machines designed by the authors were compared: a 12/14 dual-channel brushless direct current motor (DCBLDCM) with permanent magnets and a 12/8 dual-channel switched reluctance motor (DCSRM). Information is provided here on the winding configuration, the parameters, and the power converters of both machines. We developed mathematical models of the DCBLDCM and DCSRM which accounted for the nonlinearity of their magnetization characteristics in dual-channel operation (DCO) and single-channel operation (SCO) modes. The static torque characteristics and flux characteristics of both machines were compared for operation in DCO and SCO modes. The waveforms of the current and the electromagnetic torque are presented for DCO and SCO operating conditions. For DCO mode, an analysis of the behavior of both machines under fault conditions (i.e., asymmetrical control, shorted coil, and open phase) was performed. The two designs were compared, and their strengths and weaknesses were indicated.

“…To overcome the drawbacks of the H‐bridge drive of the multiphase, fault‐tolerant PM motor, a two, three‐phase drive of the dual‐winding fault‐tolerant (DF) motor has been proposed and investigated in Jiang et al [5] by our research group, which can offer the advantages of high efficiency, high power density, and high fault‐tolerance. However, when the drive system operates under a phase winding fault condition, the utilisation rate of the fault‐tolerant topology will be reduced to 50% as that of the fault‐free condition due to the removal of the faulty set of windings [3–5]. In addition, the number of the power supply system for commercial aircraft is limited.…”

To adapt to the single power supply system of the aircraft, this study proposes and investigates a novel fault-tolerant drive system based on the redundancy bridge arm for aerospace applications. The proposed fault-tolerant drive system adopts a dual-winding fault-tolerant (DF) motor; the DF motor offers the advantages of magnetic isolation, physical isolation, thermal isolation, small cogging torque ripple, inhibiting the short-circuit current and high fault tolerance. The proposed fault-tolerant drive can adapt to the single power supply system of the aircraft, reduce the drive cost, and cut down the number of independent power sources and power switches. In addition, it can improve the power density, reliability, and the utilisation rate of the drive system. To realise the open-circuit fault diagnosis performance, the diagnosis and processing method of the opencircuit fault has been investigated. Then, to realise the fault-tolerant performance, a novel space-vector pulse-width modulation (SVPWM) fault-tolerant control strategy is proposed. Finally, the performances of the fault-tolerant drive have been verified by simulations and experiments. The research results verify the reliability and effectiveness of the proposed fault-tolerant drive system based on the redundancy bridge arm and SVPWM fault-tolerant control strategy.

“…One of the areas FT is often considered is electrical drives assisted systems, for example actuators, fuel pumps and startergenerators in more-electric aircraft system and power steering, motor and generator in electric automobiles. The key challenge involved in implementation of FT concept within the electric drive systems is to achieve the required level of reliability whilst satisfying both fail safe and availability requirement at event of a fault [1][2][3][4]. To overcome this, complete redundant system is often adopted whilst the system is designed to meet the reliability level.…”

In Permanent Magnet (PM) machines, a turn-turn Short-Circuit (SC) fault is the most critical fault to eradicate. The fault introduces high SC current in the shorted turn which may consequently lead to secondary faults unless the fault is appropriately controlled. This paper proposes feasible conductors' placement in a slot of PM machine to minimize such turn-turn fault current. In order to minimize the fault current, the conductor arrangement in a slot is optimized using multi-objective Genetic Algorithm (GA) incorporating with both analytical and Finite Element (FE) numerical tool. The possible combinations of conductors' placement are set as variables and optimized for a given machine which is designed for safety critical applications. It is shown that the fault current associated to a single turn fault can be significant for the random winding placement even though the remedial strategies are put in place. It is also shown that the fault current can be limited significantly by rearranging the winding placement in a way to share slotleakage fluxes. This is confirmed via experiment on E-core. Influences of the winding arrangement on both frequency dependent resistances and windings capacitances are experimented. It is demonstrated that adopting the winding arrangement that shares the slot-leakage flux effectively benefits to minimize the AC losses in addition to improved fault tolerance. But it increases the turn-turn capacitances whose effect however can be neglected as the resonance frequency occurs beyond the operational frequency range of the machines of interest.
