“…The current-carrying conductor dissipates heat. AC and FEC in stator dissipate heat and the excessive heat can result in damage of winding insulation and lead to an inter-turn short circuit which is a fault condition (Zhao et al, 2020). Therefore, thermal analysis is performed for FEFSM to get the temperature of windings to verify that the machine would not undergo a short circuit fault.…”

“…Authors in Li and Wang (2019) performed a thermal analysis to analyze short circuit positions in the winding, thermal deformation due to excessive heat generation and thermal stress on magnetic poles of hydro generators. Authors in Zhao et al (2020) performed a thermal analysis to investigate Inter turn short circuit faults in Permanent magnet synchronous machine using the finite element method (FEM). Factors that affect the rise in short circuit current are also being researched in the manuscript.…”

Purpose Field excited flux switching machines (FEFSM) are preferred over induction and synchronous machines due to the confinement of all excitation sources on the stator leaving a robust rotor. This paper aims to perform coupled electromagnetic thermal analysis and stress analysis for single phase FEFSM as, prolonged high-speed operational time with core and copper losses makes it prone to stress and thermal constraints as temperature rise in machine lead to degraded electromagnetic performance whereas the violation of the principle stress limit may result in mechanical deformation of the rotor. Design/methodology/approach This paper presents the implementation of coupled electromagnetic-thermal and rotor stress analysis on single-phase FEFSM with non-overlap winding configurations using finite element analysis (FEA) methodology in JMAG V. 18.1. three-dimensional (3D) magnetic loss analysis is performed and extended to 3D thermal analysis to predict temperature distribution on various parts of the machine whereas Stress analysis predicts mechanical stress acting upon edges and faces of the rotor. Findings Analysis reveals that temperature distribution and rotor stress on the machine is within acceptable limits. A maximum temperature rise of 37.7°C was noticed at armature and field windings, temperature distribution in stator near pole proximity was 35°C whereas no significant change in rotor temperature was noticed. Furthermore, principal stress at the speed of 3,000 rpm and 30,000 rpm was found out to be 0.0305 MPa 3.045 MPa, respectively. Research limitations/implications The designed machine will be optimized for improvement of electromagnetic performance followed by hardware implementation and experimental testing in the future. Practical implications The model is developed for axial fan applications. Originality/value Thermal analysis is not being implemented on FEFSM for axial fan applications which is an important analysis to ensure the electromagnetic performance of the machine.

“…The coupling effect-electro-thermal-is found important because the high temperature rise results in the increase of the fault resistance, which reduces predicted fault current and hotspot temperature. The various factors that affect the amplitude of the SC current in PMSMs are investigated in [48] based on an FEM model, namely load, speed, fault location and branch inductance. Remarks are made with regards to current and voltage harmonics, current differences between parallel branches, and torque ripples (2nd, 4th and 8th harmonics).…”

Research on fault detection (FD) and condition monitoring (CM) of rotating electrical generators for modern wind turbines has addressed a wide variety of technologies. Among these, permanent magnet synchronous generators (PMSGs) and the analysis of their electromagnetic signatures in the presence of faults deserve emphasis in this paper. PMSGs are prominent in the offshore wind industry, and methods for FD and CM of PMSGs based on electromagnetic measurements are extensively discussed in academia. This paper is a concise review of FD and CM in wind turbines and PMSGs. Terminology and fundamentals of PMSG’s operation are introduced first, aiming to offer an easy read and good reference to a broad audience of engineers and data scientists. Experience and research challenges with stator winding failures are also discussed.

“…The long-time operation of singlesided VFPMLM is limited by heat dissipation. If the temperature surpasses a particular allowable range, it will cause the electromagnetic performance to decrease and leads to inter turns short circuit fault [33]. The flow of current through the conductor causes heat dissipation and loss of power.…”

A new Single-sided Variable Flux Permanent Magnet Linear Machine with flux bridge in mover core is proposed in this paper. The flux bridge prevents the leakage flux from the mover and converts it into flux linkage, which greatly influences the performance of the machine. First, a lumped parameter model is used to find the suitable coil combination and no-load flux linkage of the proposed machine, which greatly reduces the computational time and drive storage. Secondly, the proposed machine replaces the expensive rare earth permanent magnets with ferrite magnets and provides improved flux controlling capability under variable excitation currents. Multivariable geometric optimization is utilized to optimize the leading design parameters like split ratio, stator pole width, width and height of permanent magnet, flux bridge width, the width of mover’s tooth, and stator slot depth at constant electric and magnetic loading. The optimized design increases the flux linkage by 44.11%, average thrust force by 35%, thrust force density by 35.02%, minimizes ripples in thrust force by 23%, and detent force by 87.5%. Furthermore, the results obtained by 2D analysis are verified by 3D analysis. Thermal analysis is done to set the operating limit of the proposed machine.
