“…The fault of the phase winding and the rectifier can be divided into short-circuit fault and open-circuit fault [21]. The short-circuit fault of the rectifier may cause the electric source or phase winding short-circuit, which will bring a huge short-circuit current and is very dangerous to the whole system.…”

“…In the next-generation transportation system, the feature of electrification, strong connection, automation, and fault-tolerant technologies will benefit a lot to improve the future vehicles [16][17][18][19]. To further improve the reliability of the generation system, the multiphase machines can be applied because they can continue to run even with one or two open-circuited phases [20][21][22]. Although the 8/6-pole four-phase fault-tolerant doubly salient PM machine had been designed to offer fault-tolerance with a high torque [23], it is very difficult to make it as a fault tolerant generator because its flux cannot be well controlled.…”

In order to improve the reliability of a more sustainable mobility generator, a four-phase Doubly Salient Electro-Magnetic Generator (DSEG) and its phase-isolated rectifier are proposed in this paper. The mathematical model of the machine and fault-tolerant rectifiers is proposed, which indicates that the four-phase fault-tolerant DSEG should have symmetric phases. With the asymmetry analysis of the traditional 8/6-pole DSEG, a new 12/9-pole DSEG with symmetric phases is proposed. The four-phase full bridge rectifier, positive half-wave rectifier and four-phase H bridge rectifier are presented. The voltage waveforms, no-load characteristics and loading characteristics with different rectifiers will be given based on the simulation and the experiment on a prototype of DSEG, and the results show that the four-phase H bridge rectifier has the best fault tolerant no-load characteristic and external characteristic, except that it needs more diodes.

“…As a result, the redundant motor system has been widely applied in the aircraft actuation system. To guarantee the post‐fault performance under the phase short‐circuit fault condition, the slot shape design is proposed by increasing the phase inductance to restrain the short‐circuit current [15, 16]. However, the anti‐short‐circuit design may result in the torque density degradation of the redundant PMSM, which will cause the flight performance degradation.…”

This study proposes an optimisation approach of high torque density with guaranteed anti‐short‐circuit performance for the dual redundant permanent magnet synchronous motor (PMSM) in an aerospace application. The 10‐pole/12‐slot dual redundant PMSM with concentrated single‐layer windings is firstly proposed, which can restrain the short‐circuit current by the slot design to increase the phase inductance. Since the anti‐short‐circuit design may result in the torque density degradation of the dual redundant PMSM, the influence of the slot parameters on the torque performance of the dual redundant PMSM is thoroughly investigated, including the electromagnetic torque, braking torque, and no‐load torque. Furthermore, the genetic algorithm‐based optimisation method is proposed to maximise the torque density of the dual redundant PMSM, while the anti‐short‐circuit performance can also be guaranteed. Simulation and experimental results are conducted to verify the effectiveness of the proposed optimisation method.

“…In recent years, many scholars have studied the open‐circuit fault of stator windings. Some scholars have studied the control method of permanent magnet (PM) machine open‐circuit fault in detail and proposed different control methods for different machines [11–14]. Some scholars also provide effective solutions for open‐circuit fault diagnosis of PMs and induction machines [15–17].…”

As the core of the distributed generation system, the health status of high‐speed permanent magnet generator (HSPMG) has attracted much attention. HSPMG is often used in military, rescue and other fields. When the open‐circuit fault of HSPMG stator winding occurs, it will seriously affect the operation stability and power supply reliability. In this study, a 117 kW, 60,000 rpm HSPMG is taken as an example, and a 2D finite element model is established. The accuracy of the model is verified by comparing the calculated results with the experimental data. By the field‐circuit coupling method, the magnetic field changes pre‐and post‐fault is analysed, and the mechanism of magnetic field spatial distribution changes post‐fault is revealed. In addition, the changes in eddy current loss pre‐and post‐fault are analysed. The influence of the harmonic magnetic field and the rotating magnetic field produced by negative sequence current on eddy current loss is studied, and the dominant factors effecting eddy current loss post‐fault are investigated. The study provides some useful conclusions for HSPMG fault analysis.
