Abstract :This paper is carried out to find out an easy way to determine an advisable and acceptable ratio between stator and rotor tooth width in switched reluctance motors for smoother magnetic field energy, torque and output power profile. As known, different switched reluctance motors insert ignore into journalissuearticles values(SRMs); have different usage areas because of their different constructions causing different torque, current-voltage and power characteristics. Considering all these effects, eight different SRM designs were held. The designed motors only have different rotor tooth structure. In order to exhibit the most suitable stator/rotor tooth width ratio for an application, software called FEMM 4.2 and LUA scripting language utilizing finite element method insert ignore into journalissuearticles values(FEM); have been used. The comparison of dynamic output for each motor provides the basis for discussion on the relationship of performance of SRM relating to its physical size. In this study; the differences among the motors designed are explained and the selected and verified simulation results are presented.
