“…The result from the 180° shifting makes the rotor tends to align with the stator poles based on the flux movement in a westerly direction through horizontal stator poles. Therefore, each reversal of current directions in the armature causes the stator flux vector to switch between horizontal and vertical directions, hence introducing the name FSM [5].…”

<span>Recently, a three-phase Field Excitation Flux Switching Motor (FEFSM) using salient rotor has been introduced, suitable for high torque, high power as well as high speed diverse performances due to their advantages of easy rotor temperature elimination and controllable field excitation (FE) flux. However, existing FEFSMs are found to have low torque performance as the salient rotor structure has caused longer flux path, and consequently weak flux linkage. Therefore, a new structure of a single-phase FEFSM using segmental rotor and non-overlap windings is proposed. There are two valuable findings found in this topology, first is less copper loss due to the non-overlap windings between armature and FE coils, and secondly the segmental rotor structure has produces shorter flux path to produce high torque, less rotor weight as well as robust rotor at high speed condition. Flux linkage, back-emf, average torque and output power characteristics of the initial and optimized designs have been investigated and compared using 2D Finite Element Analysis (2D-FEA) through JMAG Designer version 15. Based on the 2D-FEA analysis, the average torque has increased by 81.3% to 1.65 Nm, while the output power of 466.5 W, increased of 68.2%. In conclusions, a FEFSM using segmental rotor and non-overlap windings is considered as the best single-phase motor due to their optimal performances and less copper loss.</span>

Field excitation flux switching machines (FEFSMs) in which their torque performance produced by interaction between armature and field excitation (FE) coils have been widely designed for various applications. In this regard, three-phase salient rotor FEFSM with overlap windings is considered the most suitable candidate for high speed applications because of their advantages of flux controllability, and robust due to single piece of rotor structure. However, the overlap windings cause a high copper loss, hence efficiency of the motor becomes low and higher stack length. Besides, the salient rotor structure is found to produce low torque performance due to the longer flux path in stator and rotor yielding weak flux linkage. In this paper, a new single-phase FEFSM using non-overlap windings between armature coils and FE coils is proposed. Both non-overlap windings FEFSMs with salient and segmental rotors have been designed using JMAG Designer version 15 and the investigation process is conducted via 2D finite element analysis. The proposed motor performances verification has been done by comparing the results of flux linkage, flux line and distribution, flux strengthening, various torque capability, and torque-power versus speed characteristics. As a conclusion, single-phase non-overlap windings FEFSM using segmental rotor with power, torque and speed capabilities of 277.5 W, 0.91 Nm and 2,899 rpm, respectively considered as the best candidate for low torque high speed applications.
