“…Flux-switching permanent magnet machines are promising candidates for applications where high torque density, high speed or easy thermal management are required, as the case in the automotive industry [1]. The idea of flux-switching stems from the 1950s where it was applied on a single-phase machine [2] whereas one of the first poly-phased machines based on this principle was investigated in the late 1990s [3].…”

“…As a result, the dominant vibration mode can be as low as 1 or 2 and thus PM fractional-slot machines are generally noisier than integer slot ones. Moreover, compared to other conventional fractional-slot PM machines having same overall dimensions, FSPM machines have thinner stator teeth and reduced slot areas due to PMs placed between them [1]. FSPM machines being based on the flux concentration principle, which allows high torque density performance [5], thin stator teeth lead unfortunately to high local magnetic saturation, and to substantial magnetic stress and vibrations [4].…”

Abstract-This paper deals with the computation of vibrations and noise of electromagnetic origin for 'U'-shaped stator core flux switching permanent magnet (FSPM) machines. The investigation concerns a family of FSPM stator/rotor configurations with 12 slots and 10, 11, 13, and 14 rotor poles. More precisely, the study focuses on the influence of different number of rotor poles on the sound power level of U-core FSPM machines. Electromagnetic forces acting on the stator frame inner surface are calculated with the Maxwell stress tensor thanks to 2-D finite element (FE) simulations. The local magnetic force density serves then as a boundary condition to the 3-D finite element vibrational simulations of the whole stator frame with housing. Finally, obtained displacements help the authors to conduct the acoustic computations using a dedicated 3-D FE analysis model. The obtained vibro-acoustic spectra help electric machines designers to make appropriate choice of stator/rotor pole combination with respect to specifications at early stages of the design process.

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.
