“…Gritli et al [88] analyze the voltage and current spectrum in both the α 1 -β 1 and α 5 -β 5 (x-y) planes of an asymmetrical six-phase SPMSM with distributed windings. It is concluded that the magnitudes of the fundamental and third-order voltage/current harmonics in the α 5 -β 5 plane can be used as indicators of turn failures, although the fault location is not identified.…”

“…Nearly all of these alternatives are able to identify the faulty phase [89,90,92,93,96,[99][100][101] or at least its winding set [97]. Most of them are focused on turn SC [61,[88][89][90][91][92][93][94]96,97,99], which is actually the most troublesome type of stator SC. Some of these procedures do not need extra sensors or circuits [88,89,91,93,96,97,100].…”

Some of these procedures do not need extra sensors or circuits [88,89,91,93,96,97,100].

“…All the ones shown in Table 8 are proposed for PMSMs. Only a few of the existing techniques exploit the particular characteristics (secondary subspaces) of multiphase drives in comparison with three-phase ones [88,89]. Thus, future research may attempt to take advantage of the extra DOFs of these drives so as to improve the features (e.g., discrimination from other faults) of many of the existing approaches, also in cases different from turn SCs in PMSMs.…”

“…Some others, which rely on the instantaneous power [97], zero-sequence voltage [61], or zero-sequence current (for FB VSC) [91], could also be extrapolated to three-phase systems without significant modifications. On the other hand, there are some approaches that keep track of the asymmetries produced by the stator SC in the secondary VSD planes [88,89], thus exploiting the particular features of multiphase drives. In any case, most of the detection methods are designed specifically for turns SCs in PMSMs [88][89][90][91][92][93][94]96,99], and only some of them [61,89,99,100] have been proved to be able to distinguish from other (although few) faults.…”

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.

Rotor magnets are critical components, which in case of fault, directly affect the performance of drives based on permanent magnet synchronous motors. Thus, monitoring the rotor magnets status is essential to ensure both high level of efficiency and service continuity. The present study focuses on the investigation of a new full-time domain-based method for the diagnosis of incipient rotor magnet demagnetization in a vector-controlled asymmetrical six-phase surface-mounted ac permanent magnet synchronous motor. The proposed strategy evaluates the rotor magnet demagnetization using a fault index derived from the control signals synthetized in the 5 th subspace, and already available in the control system platform. The main advantages of the proposed new strategy are its simplicity of implementation, and effectiveness even under time-varying operating conditions as the employed control signals in specific subspaces have a dc behavior. Extensive numerical simulations and experimental tests, carried out at different speed and load levels, have shown the validity of the proposed method, leading to an effective diagnostic procedure for a vector-controlled asymmetrical six-phase surface-mounted ac PMSM.
