Abstract


A new machine Switching Flux machine (SFM) has been highlighted during recent research, having all the active parts on the stator with robust structure of rotor. SFM has three major types with respect to their excitation source. Permanent Magnet Switching Flux Motor (PM-SFM) Field Excitation Switching Flux Motor (FE-SFM) and Hybrid Excitation Switching Flux Motor (HE-SFM). PM and FE coil are the main sources of flux generation in the stator of (PM-SFM) and (FE-SFM) respectively. While in HE-SFM both PM and FE coil are combined to produce flux linkage in the armature coil. This paper presents the comparison between single phase FE-SFM and three phase FE-SFM with segmental rotor. By the use of segmental rotor flux is switched in the armature circuit as rotor rotates. Initially, the coil arrangement tests are examined to confirm the operating principle of the motor. Furthermore, the profile of flux linkage, induced voltage, cogging torque, flux strengthening, and torque characteristics at various armature current densities are observed based on 2D- finite element analysis (FEA).
