Special Issue Information

Dear colleagues,

Flux-switching brushless machines have a plethora of inherent advantageous characteristics: All magnetic sources located in the static armatures simplify and ease cooling, which consequently allows to ensure a stable performance over a wide area of operations, and a completely passive moving armature that allows an easier high speed operation. These characteristics make flux-switching brushless machines suitable for a large variety of applications, ranging from the classical to the relatively new, as electric and hybrid electric vehicles, renewable energy generators, more electric aircrafts, industrial drives, and automations.

A large variety of flux-switching machine topologies have been and are still being developed by both the academic and industrial communities. Hence, the main objective of this Special Issue will be to gather the ideas of the research community worldwide in a common platform and to present the latest advances and developments in the design, modeling, and control of flux-switching machines for different applications. Topics of interest of this Special Issue include, but are not limited to:

  • New rotary, linear, and multi-DOF flux-switching machines topologies;
  • Single and hybrid excited flux switching machines;
  • Multiphysical modeling of flux-switching machines;
  • Noise and vibrations issues of flux-switching machines;
  • Control of flux switching motors and generators;
  • Applications of flux-switching motors and generators;
  • Fault tolerant and diagnosis of flux-switching machines.

The aim of this paper is to present the design and modeling of a machine that possesses some advantageous characteristics for wind energy conversion applications. The studied machine is a double stator inner rotor axial airgap flux switching permanent magnet machine (AFSPM). The paper will start by presenting this type of machine and its points of interest. Then, it will continue by introducing the constructed prototype and its specifications and structure. This prototype has been designed based on a reference specification used at GREAH to develop different prototypes and compare their performances. The second part will introduce the reluctance network model specifically constructed for this type of machine. The constructed model was validated by comparing its results to the results from the finite element method model. Finally, the experimental results will be presented and compared to the reluctance network (RN) model results where satisfying agreement between both results was obtained. Full article

This paper presents general design considerations of a partitioned stator switched flux hybrid magnet memory machine (PS-SF-HMMM). The armature windings and permanent magnets (PMs) are placed on two separate stators, respectively, in the PS-SF-HMMM, and thus both high torque density and wide flux regulation capability can be obtained. The topology and working principle of the machine are introduced briefly first, and then different magnet arrangements and stator/rotor pole combinations are investigated. In addition, various design parameters are optimized based on finite element (FE) methods. Finally, a prototype is fabricated to experimentally validate the FE results. Full article

Due to the increasing need for direct-drive wind turbines, a large number of papers are dedicated to the optimization of low-speed wind generators. A permanent-magnet flux-switching machine can be a valuable option to use in such applications. This paper describes the optimization procedure of a direct-drive flux-switching wind generator. The average losses, the required converter power, and the cost of permanents magnets were chosen as the optimization objectives. To reduce the calculation efforts during the optimization, a method to construct the substituting load profiles is proposed. Two-mode and three-mode substituting profiles were constructed on the basis of the nine-mode initial profile. The losses calculated under the two-mode, three-mode, and nine-mode profiles accurately coincided, which supported the use of the low-mode substituting profiles instead of the initial one. During the optimization, the average losses decreased by 30%, which corresponded to an increase in the average efficiency by almost 6%. The required converter power was decreased by 10%. The total active material mass, cogging torque, and torque ripple were also slightly decreased. Full article

Currently, studies of flux switching machines are actively underway owing to several advantages of these machines, including their sturdy rotor structure and high output capability. This paper deals with an outer-rotor hybrid-excited flux-switching machine (FSM). The proposed machine embraces a homopolar structure and utilizes permanent magnets (PMs) for field excitation and a high-temperature superconducting (HTS) coil for flux regulation. The stator houses the HTS field coil, PMs, and armature windings. The outer rotor consists solely of an iron core. Thus, the machines are cost effective and can serve as a solution to the design and fabrication complexities of field current supplying and cooling systems. In this paper, the machine performance outcomes are analyzed using the 3D finite element method (FEM), and the validity of the proposed machine is verified. Full article
