“…Moreover, considering Eqs. (10) and (11), 𝜎 𝑑 = 𝜎 𝑠 = 0 represents the machine with no eccentricity fault. Mixed eccentricity can be modeled by 0 < 𝜎 𝑠 < 1 and 0 < 𝜎 𝑑 < 1.…”

“…Although fault analysis and condition monitoring of the FSMs have received less attention than other EMs, certain studies have concentrated on them. The most well-known study on the FSM faults analysis, according to the authors' knowledge, is presented in [2][3][4][5][6][7][8][9][10]. In [2], static eccentricity is detected by induced voltages of the open-circuit phase windings.…”

“…In [9] armature winding short-circuit and open-phase faults are detected for a wound-field FSM generator, where the field and stator current waveforms are obtained under the faults. Additionally, in [10], effect of different faults on a PM-FSM performance is analyzed, where detection method is not investigated. Fast Fourier Transform (FFT) for the current signature anal-ysis is used as a tool for the fault analysis in many works.…”

This paper presents a Permanent Magnet Flux Switching Motor (PM-FSM) performance analysis in healthy and faulty cases by a mathematical modeling method. A new fault detection and separation technique is described using six search windings (SWs), each obtained by two series search coils (SCs). The goal of the paper is to consider Static, dynamic, and mixed eccentricities (SE, DE, and ME), inter-turn (IT), and PM demagnetization (PD) faults. The style of the induced voltages is employed for the described fault detection/separation, where the IT and PD faults location is possible by using six open-circuit voltage of the search windings. Since each fault has a particular waveform style in the induced voltages of the SWs, the proposed method yields a real-time fast technique. The method is independent of the motor load thanks to the voltage-based approach, where the rotor rotation is the only necessity of the proposed method. Although the method used twelve SCs in the motor structure, distinguishing the various faults and their location possibility are its advantages compared to other SC-based techniques that use fewer SCs. The well-known flexible Magnetic Equivalent Circuit (MEC) with adjustable accuracy is used to analyze healthy and faulty motors by a unique model thanks to its flexibility and shorter processing time compared to the Finite-Element Method (FEM).

“…Based on structure, FSMs are divided into inner rotor FSM [8], outer rotor FSM [9,10], dual rotor FSM [11,12] and dual stator FSM [13]. With main concern in simple robust inner rotor topologies, several designs are recently reported in literature including π-shaped stator [14], multitooth [15], V-shaped [16] and square envelope [17].…”

Flux switching machines (FSMs) encompass unique features of conventional direct current machine, permanent magnet (PM) synchronous machine and switch reluctance machine. Permanent magnet FSM (PMFSM) is capable of high torque density and applicable for high-speed application, however conventional PMFSM exhibits demerits of high PM volume, high torque ripples and significant stator flux leakage. In this paper, a novel consequent pole E-core stator PMFSM is proposed and compared with conventional topology utilising 2D finite-element analysis (2D-FEA). Finite-element analysis revealed that proposed design enhanced flux modulation effects by introducing flux bridges and flux barriers as a result reduced cogging torque by reducing 46.53% of the total PM volume, reduce torque ripples by reducing PM slot effects and reduce flux leakage utilising flux bridges in the stator. Furthermore, analytical model for flux linkages, cogging torque, mechanical torque, no load and on-load magnetic flux density (MFD) is developed for initial design of conventional and proposed model. 2D analytical methodologies resolve equivalent magnetic circuits for open-circuit flux linkages, Fourier analysis for cogging torque, Laplace equations for MFD and Maxwell stress tensor for mechanical torque. Finally, results obtained from 2D-FEA and analytical methodologies are validated and compared.
