For aerospace electrical machines (EMs), the partial discharge (PD) risk is becoming much more severe due to higher dc link voltage levels and faster switching devices. Traditionally, EMs for safety-critical applications mainly rely on overengineering methods guarantee reliability. However, a recent shift toward reliability-oriented design, which based understanding physics of failure, allows meeting reliability requirements while ensuring performance. From perspective methodology, PD-free...

Compact and efficient electric drives are desirable in transport applications an increased dc-link voltage value combined with fast-switching devices represents a promising solution for achieving light energy-efficient systems. Nonetheless, the higher dc bus wide-bandgap device greatly raise electrical stress (i.e., maximum interturn voltage) of inverter-fed machines (EMs) insulation jeopardizing overall reliability. Thus, lifetime prediction EMs gained more attention recently. Short-duty...
For a five-phase permanent magnet synchronous machine (PMSM), the third-order harmonic back EMF is increased by changing shape of for increasing average torque in healthy operation.

Five-phase machines are increasingly adopted in high-reliability applications because of their fault-tolerant characteristics. In this framework, single-phase short-circuits (SC) fault tolerant control has drawn increasing interest. One issue with is the increased copper loss that a machine experiences post-fault operations. This study adopts not only full-range minimum (FRML) SC application but also its online tuning process. To achieve FRML strategy, contact resistance and motor speed...
Due to the different design optimization, five-phase electrical machines can have a nonnegligible distortion in their back electromotive force (EMF) waveform. Most fault-tolerant control methods for this machine used extra fundamental and third-order harmonic currents eliminate torque fluctuation due nonsinusoidal EMF, bringing high copper loss.

With the increase of high-reliability requirements, multiphase machine draws considerable attention from field transportation electrification. However, presence third-order harmonic subspaces in five-phase machines poses greater challenges for high-speed applications, particularly due to low sampling-to-fundamental (S2F) frequency ratios observed higher-order subspaces. In this case, electrical speed subspace is three times that fundamental subspace. The closed-loop control system...
