Abstract
In this paper, we analyze the stator-rotor design of a double salient reluctance machine using total surface gap
area. The high number of poles in a 4-phase reluctance machine makes it suitable for the analysis. An expression
is derived for the total surface gap area which includes the sum of the area of the air-gap (between the inner
stator radius and the outer rotor radius), the area between the gaps of the stator poles and the area between the
gaps of the rotor poles. The rated torque and the rated power output are expressed through the total surface gap
area and the geometrical parameters. The total surface gap area is used to predict the torque ripple and the
average torque developed by the machine for different pole arcs, air gaps, number of poles, number of phases
and frequencies which are investigated by MATLAB simulation. The stator and the rotor of the machine are
drawn by ANSYS software for the purpose of visualization.
