“…Because of the air-gap flux distortion, FSCWs are normally only used in PMSMs, never in IMs [2,34,259]. In addition, FSCWs typically offer lower reluctance torque [270,476].…”

“…For instance, double-delta connection could be set in a six-phase motor with asymmetrical WSA. Nonetheless, to the knowledge of the authors, these possibilities have barely been explored so far, with the exception of a multisector WSA based on three deltas [270].…”

“…In case HB VSCs are adopted, the tolerance to stator SC faults may be improved by the type of stator phase connection. It has been shown in [270], taking a nine-phase PMaSynRM driven by three-phase HB VSCs as an example, that using three deltas yields lower current under turn faults than three stars. This is explained by the fact that the zero-sequence current flowing within the loops in the former case contributes to reduce the flux linkage in the shorted turn/s, even though the circulating current cannot be actively controlled.…”

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.

“…As the machine has triple 3-phase sets, the mutual coupling between the two healthy 3-phase sets and one faulty 3-phase set will influence the fault current and resultant copper loss. It has been shown in [21] that when a turn-to-turn SC located in slot B2 and slot B4 which are marked by the two black quadrangles shown in Fig. 2 (a) takes place, the SC current and copper loss are the highest.…”
