“…Then, taking the output voltage and fault tolerance as the optimization objectives, GA is used to globally optimize the key structural parameters of the WEDSM. The finite element simulation and experimental results show that the multielement fusion optimization method combined with magnetic field modulation theory and intelligent algorithms has higher optimization efficiency [82].…”

The Electrically Excited Doubly Salient Variable Reluctance Machine (EEDSVRM) is a new type of brushless machine designed according to the principle of air gap reluctance change. There is neither permanent magnet steel nor excitation winding on the rotor. The rotor is made of silicon steel sheets, thus the structure of the variable reluctance machine is very simple. There are many optimization methods for this type of machine optimal design, such as novel machine topology optimization, finite element simulation-based optimization, mathematical analysis-based optimization, intelligent algorithm-based optimization, and multiple fusion-based optimization. Firstly, this article introduces the basic structure and working principle of the EEDSVRM and analyzes both its common regularity and individual difference. Then, the different optimization design methods of EEDSVRM are reviewed, the advantages and disadvantages of the different optimization methods are summarized, and the research interests of the optimization design of variable reluctance machines in the future are prospected.

“…Recently, with the fast development of the electric vehicle and more electric aircraft, variable flux reluctance machines (VFRMs) play a critical role in supplying electrical power for the electric drive system and the battery storage [1,2,3]. The VFRM with DC field and AC armature windings evenly wounded on each stator pole is a promising magnetless candidate for onboard generator, evolving from the switched reluctance motor with the advantage of a robust rotor, which enables VFRMs to be applied in extremely rugged environments for power generation [4,5,6]. Therefore, high reliability is required for the generator operation, and fault diagnosis in the early stages can ensure the stability and reliability of the power system.…”

To improve the reliability of the variable flux reluctance machines (VFRMs) in the early stages, this letter proposes a novel fault feature for armature winding short-circuit (AWSC) fault in four-phase VFRMs. First, the harmonic characteristics of field induced voltage are researched theoretically in detail under normal and AWSC conditions. Then, a diagnosis method based on the harmonics of the field induced voltage is proposed and analyzed by simulation. Finally, related experiments are conducted to verify the proposed method. The proposed diagnosis method is simple and feasible, which can realize reliable protection of the power generation system for safe operation.
