Abstract :
In this paper a three-phase field excitation switched flux (FESF) motor where both armature coil and field excitation (FE) coil placed on the stator is investigated. The rotor is design with separately segmental pole so that flux generated from FE Coil can be fundamentally placed in adjacent with flux of armature coil. Thus, the coil end length of both FE Coil and armature coil are reduced, hence increasing the motor efficiency when compared with FESF motor with single piece rotor, and overlapped FE Coil and armature coil windings. In this paper design investigation and analysis of 12S-8P and 24S-10P FESF motor with segmental rotor are investigated. Moreover, coil test analysis, FE Coil flux characteristics, flux interaction between FE Coil and armature coil, flux distribution, and torque characteristics are also compared. As conclusion, the 24S-10P FESF motor with segmental rotor gives much higher performance when compared with 12S-8P FESF motor.
