“…Extensive experimental tests are performed in [244], including thermal results during SC faults, and even more experiments are discussed later in [242]. A modeling approach of this PMaSynRM using four-dimensional tables and taking into account the behavior under SC and OC faults is presented in [245], and extended in [235]. In [129], significant attention is paid to different types of stator SC faults, and other kinds of drive failures are also addressed.…”

“…From Table 10, the most popular multiphase machines for tolerating stator SCs are arguably symmetrical six-phase SPMSMs with single-layer 12-slot 10-pole FSCW [100,101,128,163,165,210,211,231,265]. A lot of research has also been performed recently about a nine-phase three-sector PMaSynRM with overlapping windings [97,98,129,167,224,[235][236][237][238][242][243][244][245]270], although this one has only been employed by a single research group in the literature so far. Based on the preceding survey, it can also be pointed out that innovative machine structures and winding layouts are still being designed nowadays for multiphase drives with tolerance to stator SCs with excellent unprecedented features (see, e.g., [209,244,249,267,268,272]).…”

“…Using three-phase HB VSCs or two n-leg HB VSCs, e.g., does not offer as much electrical isolation as single-phase ones; nevertheless, the isolation (modularity) is still higher than in an n-phase VSC with common dc link, it is simpler than installing n H-bridges [244,373], and it avoids the zero-sequence current associated with FB VSCs [13,273]. For multiphase drives that are tolerant to switch SCs, topologies based on three-phase HB VSCs are employed in [27,168,235,243], and dual HB VSCs in [273].…”

“…Increasing the VSC modularity and isolation between VSC units, if possible, is in principle also advisable for improving the reliability in the phase of switch SCs. For example, topologies based on multiple H-bridges [130,240], dual HB VSCs [273], or multiple three-phase HB VSCs [27,168,235,243] are common in fault-tolerant drives.…”

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.
