“…In the case of an SRM with four poles per phase, the short-flux path solution (NSNS) is usually selected [8,9]. This configuration of the poles of a single phase may also be used in the case of a dual-channel power supply [8,9,11,12]. It ensures the most advantageous motor parameters for a dual-channel power supply.…”

“…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.

The classical switched reluctance motors (SRMs) often suffer from drawbacks such as low power and torque densities, high torque ripple, mutual coupling, etc., which limit their industrial applications. This paper presents the analysis and development of two novel three-phase SRMs with hybrid magnetic paths comprising six E-shaped modular stators and three segmental common rotors, termed as the modular SRMs (MSRMs), for electric vehicle applications. The machine topologies with different winding arrangements are described. The voltage and output power equations are analytically derived, and some design particularities and parameters are discussed. The field distributions and static magnetic characteristics of an MSRM with double coil are analyzed by using 3-D finite-element method. After that, two MSRMs with different winding arrangements, namely a doublecoil MSRM and single-coil MSRM, are analyzed and compared to evaluate the distinct features of this novel MSRM, accompanied with a classical three-phase 6/4 SRM. The comparison includes static magnetic characteristics, mass of iron core, normal dynamic, and fault-tolerant performances. It is shown that the double-coil MSRM appears to have better characteristics such as higher torque production capability, lower torque ripple and cost, higher torque and output power densities, and higher reliability and fault tolerance. For experimental verification, laboratory testing of a doublecoil MSRM is developed, and the simulated and measured static inductance characteristics and dynamic performances correlate well.

“…1. One of the common fault tolerance increasing solutions is the division of the phases into individual coils, called channels [7], [8], [9]. This way a fault of a channel will not influence the operation of the other channels of the same phase or of other phases.…”

Abstract-The electrical drive systems used in automotive applications has to be both reliable and of high performance. To fulfill these demanding requirements a modular fault tolerant switched reluctance motor is proposed, which is controlled by means of an effective direct instantaneous torque controller. In the paper both the motor and the control system are described. By simulations the working principle of the drive system is illustrated and its performances are demonstrated.
