چکیده
Double-stator switched reluctance machines have higher torque density and lower vibration and acoustic noise level in comparison with conventional switched reluctance machines. Static characteristics of a 8/6 Double-stator switched reluctance machine have already calculated using finite element method. However, no measurement has been presented for the static torque of the machine. This paper presents experimental evaluation of static torque characteristics of a 8/6 double-stator switched reluctance machine. For this purpose, an experimental setup is developed for static torque measurement of the machine for different current levels and rotor positions. Finite element calculation the static torque of the machine is also presented for the sake of comparison. It is observed that, experimental results are reasonably close to the simulation results. Streszczenie. W artykule opisano badania eksperymentalne nad maszyną reluktancyjną przełączalną 8/6 DSSRM (ang. Double-Stator Switched Reluctance Machine), mające na celu oszacowanie charakterystyki statycznej momentu maszyny. Do realizacji badań zbudowano stanowisko, pozwalające na pomiary momentu przy różnych wartościach prądu oraz pozycji wirnika. W analizie wyników wykorzystano metodę elementów skończonych. Wyniki eksperymentalne są zbliżone do symulacyjnych. (Eksperymentalne wyznaczenie charakterystyki statycznej momentu maszyny reluktancyjnej przełączalnej o podwójnym stojanie).

A Design Package for Single Tooth per Stator Pole Switched Reluctance Motors
A design package is developed for a single-tooth per stator pole switched reluctance motor, 6/4. The rather simple assumed flux path method is used to estimate the unaligned permeance including the leakage permeances and the effects of shallow slot and tooth taper. The possibility of making rotor tooth width greater than stator tooth width is examined using the developed package. The result app...
