“…Another strategy for generating phase-current references with equal amplitude for a five-phase SPMSM is presented by Yin et al [234]. The main contribution is that the d 1 -axis current is set optimally for maximizing the torque, instead of setting it to zero.…”

Multiphase drives offer enhanced fault-tolerant capabilities compared with conventional three-phase ones. Their phase redundancy makes them able to continue running in the event of faults (e.g., open/short-circuits) in certain phases. Moreover, their greater number of degrees of freedom permits improving diagnosis and performance, not only under faults affecting individual phases, but also under those affecting the machine/drive as a whole. That is the case of failures in the dc link, resolver/encoder, control unit, cooling system, etc. Accordingly, multiphase drives are becoming remarkable contenders for applications where high reliability is required, such as electric vehicles and standalone/off-shore generation. Actually, the literature on the subject has grown exponentially in recent years. Various review papers have been published, but none of them currently cover the state-of-the-art in a comprehensive and up-to-date fashion. This two-part paper presents an overview concerning fault tolerance in multiphase drives. Hundreds of citations are classified and critically discussed. Although the emphasis is put on fault tolerance, fault detection/diagnosis is also considered to some extent, because of its importance in fault-tolerant drives. The most important recent advances, emerging trends and open challenges are also identified. Part 1 provides a comprehensive survey considering numerous kinds of faults, whereas Part 2 is focused on phase/switch open-circuit failures.

“…Thanks to the benefits they offer over conventional threephase winding machines, multi-phase machines have been widely investigated in the literature [1][2][3]. Multiphase machines are frequently employed in applications requiring high reliability, such as aviation, ship motors and electric vehicle since they can operate even if one or more phases fail [4][5][6][7]. Other advantages of utilizing more than three phases have previously been highlighted in the literature, such as higher torque density, lower torque ripple, and improved electromagnetic efficiency [6,7].…”

In the recent literature, a rewinding approach was proposed to construct a rewound five-phase machine with either star-connected or combined star-pentagon winding using existing off-the-shelf three-phase stator frames. The power per phase drops by a factor of 3/5 in the five-phase machine compared to the three-phase machine. This indicates that either the rated current or voltage must be rescaled. The two options are compared in terms of drive cost and performance. The constant current -reduced voltage option is analytically investigated to determine whether reducing the operating voltage affects the operating speed/output power or not. The second contribution of this work is to determine the optimal slot/pole combinations of the existing off-the-shelf threephase stators that ensure balanced five-phase starconnected and/or combined star-pentagon windings. This has been done by comparing the harmonic mapping of the rewound machines for different slots/poles combination with the conventional five-phase machines using standard vector-space-decomposition. In addition, the leakage inductance mismatch for different slots/poles combinations of the rewound five-phase machines has been compared to the standard conventional five-phase machines. The last contribution of this paper is to compare the performance of the rewound combined star-pentagon winding with an optimally designed conventional symmetrical one (60-slots/4-poles). This has been done using 2D Ansys Maxwell transient simulation. Finally, experimental results are used to support the theoretical and analytical conclusions.

“…This type of fault is more severe and hazardous [11][12][13][14] because both asymmetrical four phases and short-circuit current would generate additional torque ripples. Extensive research has been performed on shortcircuit faults [16][17][18][19][20][21][22] to enhance the operational performance under short-circuit fault conditions [15] . A remedial phase-angle control strategy based on short-circuit current [16] was proposed by limiting reactive components of the torque ripple.…”
