This paper describes the performance characteristics and comparison results of four different types of switched reluctance motors using a two dimensional finite element analysis. These motors have 12/10 6/4,12/8, and 8/8(or isolated phase) configurations. The 6/4 configurations includes, a motor with one tooth per stator-pole, where as in 12/10 arrangement there are two teeth per stator pole. In 12/8 arrangement, a motor is of the cylindrical type with one tooth per stator pole and the other- one is of the isolated phase geometry where each phase consist of eight rotor and stator poles. The areas of ad stator pole faces jointly involving in torque production mechanism in the motors are taken -to be equal. The numerical analysis gives a better understanding of the flux distribution inside -the motors and can be used to compute, optimise motor performance and parameter b. The terminal inductance per phase the flux linkage of each stator- pole winding and-the components of leakage inductances determined and plotted for different- rotor positions and excitation currents. Finally the static torque for different forced current level sand rotor posidonsam Mopresentedfor motor.
