It is to reduce the cost of production, conveniently replace, and as a module where the sum of electromagnetic torque produced comes from each segmental stator add up together. Thus, in this paper will be focusing on the elementary analysis of a segmental stator for single phase 6Slot-12Pole and 3 phase 6Slot-15Pole Switched-Flux Permanent Magnet Machine (SFPMM) as the chosen design for analysis validation from coventional permanent magnet flux switching machine to a new segmental stator structure of SFPMM. It will be focusing on the initial design and to prove that it can be operate as a flux switching machine by implement a 2D Finite Element Analysis simulations such as a No-load analysis (flux linkage, cogging torque, back emf) and Load-analysis (average electromagnetic torque. Elementary result shows that the electromagnetic torque produce for both design are 10.6 Nm and 99.95 Nm and proved that it can produce high torque although it does not surpass the conventional SFPMM. A further research and optimization will be needed to obtain a higher torque compared to conventional SFPMM.

INTRODUCTION Flux Switching Machine (FSM) are a type of machine that utilize flux source from permanent magnet (PM) and direct-current (DC) excitation at single or dual stator stator only. The tendency of FSM shows that it is tremendously research and develop in recent years due to their advantage of separate active and non-active part. In which it is suitable for wide range of speed, application and astounding high flux density [1, 2]. Based on this advantages, researchers are applying the principle of flux switching to design an electric machine solely based on PM, DC excitation, or both such as hybrid FSM [3]. Hence, an electromechanical framework intended for such applications must be stable and dependable, where the defect parts can be effectively and promptly recover. From the literature review, Switch Reluctance Motor (SRM) and permanent magnet (PM) machine is the two highlighted research in the electrical machine for fault tolerance study. As you may know, it is naturally fault tolerant in SRM where each phase of an SRM can be considered as single and separate due to non-shared coupling. Whereby, a fault in one phase winding will have no effect towards other phase and the machine can operate solely dependent on the faultless phases [4]. While a PM machines with high phase number are designed for fault-tolerant operation. Since it have a greater torque density than SRMs, their optimal design structure is affected in order to improve the fault tolerance [5]. Besides, recent year shows that a PM machines efficient development in drive system and FEA design software attract more researcher attention. Specifically, a Switched Flux (SF) PM machines, as shown
