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.

This study introduces a doubly salient brushless dc (DSBLDC) generator with stator-field winding, which incorporates the doubly salient electromagnetic (DSEM) machine and its associated rectifier. The configuration, operation principle, and armature reaction of different generating mode are overviewed. The sizing equation is derived for the initial dimension design of the DSEM machine. Then the non-linear varying-network magnetic circuit method for preliminary design is proposed to determine the fundamental geometric parameters, the corresponding field magnetomotive force, and winding configurations iteratively, in which the magnetic saturation is taken into account. Furthermore, optimal design of the geometric parameters is comprehensively investigated by finite-element analysis, and the optimised coefficients obtained for different generating mode. The operating characteristics of the DSBLDC generator with compensation capacitors are investigated to improve the voltage regulation performance. A prototype of 12 kW DSEM machine has been designed and optimised by the proposed design methods. Experiments are performed and the results verify the predictions and the design methods. Due to the simple and robust structure without permanent magnet, as well as convenient and flexible control, the promising DSEM machine is a desirable candidate for dc power generation.

In this paper, doubly salient brushless DC machines (DS-BLDCM) with different rotor pole arcs are compared in terms of their generating and motoring operation. For generating operation, comparison of output power, output voltage and magnetic flux distribution with different rotor pole arcs are obtained by finite element analysis (FEA). For motoring operation, comparison of output torque, torque ripple and efficiency based on basic control scheme are obtained. The analysis results indicate that when the rotor pole arc is appropriately increased, the performance of DS-BLDCM will be improved. The design of the rotor pole arc of DSEM should be distinct according to different operation states.
