“…However, there is a numerical limitation for the harmonic m to be solved with adding a proper scaling of machine as explained in [19] and [20]. This numerical limitation can be also solved with changing the general form of vector potential in armature slots subdomains from (8) to (7) and adding a Dirichlet boundary condition at r 4 . Radial and tangential flux densities are shown in Fig.…”

“…Since HE-FSM used a hybrid excitation flux source, the machine has a potential to produce a higher torque output and power density, improve flux weakening performance, increase efficiency and more flux variable capability. It have been studied by most researcher broadly over a decade [8][9][10][11][12][13]. Figure 2 illustrates several HE-FSMs topologies that have been designed.…”

This paper presents performance analysis of 12Slot with various rotor pole numbers Hybrid Excitation Flux Switching Machine (HEFSM) for Hybrid Electric Vehicles (HEVs) application. HEFSM has carried out by combining the advantage of Permanent Magnet (PM) machines and DC Field Excitation Coil (FEC) synchronous machines. Previously, most of HEFSM structure having FEC windings in theta direction that create a problem of flux cancellation that will affect the performances of the machine. Thus, a design of 12Slot HEFSM with FEC wounded in radial direction is proposed to eliminate the flux cancellation effect. At first, armature coil arrangement test at no-load condition is conducted to analyze PM flux. Furthermore, induced voltage and cogging torque at open circuit condition are investigated based on 2D finite element analysis (FEA). Finally, torque and power performances are also examined at maximum FEC and armature current densities. The outcomes demonstrate that 12S-14P configuration has the highest PM flux linkage, torque, power and less distortion of back-emf waveform which are required to be used as a motor in HEVs. The highest torque and power achieved are 220.15Nm and 92.45kW, respectively.

Flux‐switching machines are a type of brushless machines with a doubly salient structure, which has excitation sources, for example, permanent magnets (PMs) and/or field‐excited windings, and armature windings on the stator, and no magnets or windings on the rotor. The flux‐switching machines have the advantages of high torque (power) density, large torque output capability, high efficiency, strong irreversible demagnetization withstand capability, good thermal dissipation and liquid cooling conditions, and favorable high‐speed operation. These advantages are particularly important for electric propulsion systems, such as electric vehicles and hybrid electric vehicles, and electric ships and airplanes. According to the excitation modes, there are three types of flux‐switching machines: permanent magnet flux‐switching (PMFS) machines, hybrid‐excited flux‐switching (HEFS) machines, and wound‐excited flux‐switching (WEFS) machines. This article presents topologies, operation principles, electromagnetic performance, and applications of flux‐switching machines. In addition, different topologies of stator and rotor are also discussed.
