“…Partition stator 12S-10P produce a good overall torque parameter for innerrotor structure [15]. High torque constant density produce by 3-phase outer rotor 12S-22P is a trade-off of low torque to magnet ratio [16]. Full-pitch winding 12S-7P PMFSM is also listed in the table mainly because its inherit good winding factor [17].…”

Flux switching machine (FSM) offer advantages such as rotor robustness and simple driving circuit compared to competing machine. This paper attempts to process the torque, volume and current information from 35 latest Permanent Magnet (PM) FSM publication into a standardized Torque Performance Indicator (TPI), which are torque density, torque constant, torque constant density and torque-magnet ratio. The distribution median shows that torque density, torque constant, torque constant density and torque-magnet ratio are 23.24kNm/m3, 0.43Nm/A, 0.616Nkm/Am3 and 30.79Nm/kg respectively. Among many design variation, outer rotor configuration produces good values as overall in the TPI. This information can be used to guide the machine designer to compare and compete based on the standardized TPI.

“…In FSM, cogging torque is due to the interaction between the permanent magnets on the stator with stator slots winding and rotating rotor which causes vibration in motors. Meanwhile, the normal quantity for safe motor operation is 10% of the output torque [5,15]. Looking at the plot, optimized design achieved cogging torque lower than the improved design making it more favourable to operate safely.…”

“…Generally, electric machines utilize different flux sources for excitation such as; permanent magnet (PM), field excitation (FE) and hybrid excitation which combines both PM and FE [2][3]. Flux switching machine (FSM) is an advance form of synchronous machine locates both armature winding and flux source in the stator and leaving the rotor without any added material, has become researchers' choice because of speed capability [4][5][6]. Invariably, transferring inner rotor to outer position generates higher torque and also offers reliable control mechanism in the vehicle through eliminating complex combustion engine in conventional vehicle [7][8].…”

<span lang="EN-US">A breakthrough in this century has been the development of electric vehicle which is propelled by electric motor powered by electricity. Already, many electric motors have been used for electric vehicle application but performances are low. In this paper, a permanent magnet motor technology using unconventional segmented rotor for high torque application is presented. Unlike conventional motors, this design, flux switching motor (FSM) is an advance form of synchronous machine with double rotating frequency. It accommodates both armature winding and flux source on the stator while the rotor is a simple passive laminated sheet steel. Conventionally, rotor of the maiden FSM and many emerging designs have focused on the salient pole, this design employs segmented rotor. Segmented rotor has advantages of short flux path more than salient rotor pole resulting in high flux linkage. Geometric topology of the proposed motor is introduced. It consists of 24Stator-14Pole using PM flux source with alternate stator tooth armature winding. The 2D-FEA model utilized JMAG Tool Solver to design and analyze motor’s performance in terms of torque with average torque output of 470Nm. The suitability of segmented outer-rotor FS motor as a high torque machine, using permanent magnet technology is a reliable candidate for electric vehicle.</span>
