Abstract

This paper presents a procedure of determination of static characteristics of switched reluctance machines (SRMs). Calculations are realized for two SRM topologies including novel configuration with 8 stator and 14 rotor poles (SRM 8/14). This configuration is based on new pole design formula introduced recently. Flux linkage and static torque characteristics are calculated for different rotor positions and stator currents using two-dimensional finite element analysis (2D-FEA). Simulation results for new SRM 8/14 and conventional SRM 8/6 with the same number of phases and outer dimensions are presented and compared. This comparison shows that new configuration can have better torque density. Therefore, new design approach should be considered to make this type of machines a more attractive for high performance HEV's (Hybrid Electric Vehicle's) drives.
