A switched-reluctance motor for aerospace application: Design, analysis and results

On-Line Open-Phase Fault Detection Method for Switched Reluctance Motors with Bus Current Measurement

“…The VTB of the SRM is a numerical model where Maxwell's equations are directly solved by the finite element method instead of using the low-order model (3) of ordinary differential equations [38]. Hundreds of research papers (as seen in for example in [26,[39][40][41][42]) show the accuracy of finite element modeling, where test data and simulation results match nearly perfectly. The FE model accounts for steel nonlinearity, geometric details (slot geometries, proper distribution of windings, correct geometry of stator and rotor), boundary conditions and correct injection of excitation.…”

Comparative study on performance characteristics of PM and reluctance machines equipped with overlapping, semi‐overlapping, and non‐overlapping windings

“…In the existing literature, several different studies on reviewing/ comparing the electromagnetic performance characteristics of different machine technologies can be found [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Different electric machine topologies have been compared and it is concluded that the PM machines, particularly having IPM topologies, are one of the best rotor topologies suitable for the electric vehicle (EV)/hybrid electric vehicle (HEV) and aerospace applications [5,6].…”

“…on the performance characteristics have also been investigated [7][8][9][10][11][12][13][14][15][16][17][18][19]. It has also shown that the switched reluctance machines namely DSRMs has also potential to be used in the aerospace applications [20][21][22]. Most of the studies performed for the DSRM are to increase the reluctance torque component by redesigning the rotor geometry [21,22].…”

An innovative natural air-cooling system technique for temperature-rise suppression on the permanent magnet synchronous machines

“…The heat transferred by radiation is ignored. The partial differential equation of the heat conduction and convection is expressed [8] as (3) where ρ is the mass density, c is the specific heat, T (K) shows mass transport of heat; {L} is the vector operator, |D| is the temperature, t stands for time, {V} is the velocity vector for conductivity matrix, and Q is the heat source rate per unit volume. It should be mentioned that for steady-state thermal analysis, the first term on the left-hand side of Eq.…”

“…The finite-element analysis (FEA), CFD, and lumpedparameter-based methodologies are employed for the entire study [7][8][9][10][11][12], [14][15][16][17][18][19][20], [24][25][26][27][28].…”
