Abstract

In this paper, a comprehensive electromagnetic performance comparison of the conventional wound field flux switching machine (WFFSM) and the double stator WFFSM (DSWFFSM) is undertaken for high torque density applications, based on finite element analysis (FEA). The initial design study reveals superior specific density and torque density of the DSWFFSM over WFFSM. Parametric analysis is then used to systematically vary key structural variables to study their influence on average torque, torque ripple, efficiency and power factor, while a multi-objective optimisation based on normalised weighted objectives is used to select the optimal designs upon which a comparative evaluation is performed to reiterate the intrinsic advantages of DSWFFSM in achieving elevated torque performance. The results show that specific torque and torque density of the DSWFFSM finally increased by 43.5% and 30.4% over the WFFSM, respectively. The torque ripple of the DSWFFSM is also finally reduced by 75.9% . To validate the FEA results, an experimental analysis is provided based on a pre-existing DSWFFSM prototype.

常规与双定子绕组磁场开关电机的参数评估与电磁性能比较

本文基于有限元分析（FEA），对传统绕线磁通开关电机（WFFSM）和双定子磁通开关电机（DSWFFSM）在高转矩密度应用中的电磁性能进行了全面比较。初步设计研究表明，DSWFFSM比密度和扭矩密度优于WFFSM。然后使用参数分析系统地改变关键结构变量，研究其对平均转矩、转矩脉动、效率和功率因数的影响，同时使用基于归一化加权目标的多目标优化来选择最优设计，并对其进行比较评估，以重申DSWFFSM在实现更高转矩性能方面的内在优势。结果表明，与WFFSM相比，DSWFFSM的比转矩和转矩密度分别提高了43.5%和30.4%。结果表明，该系统的转矩脉动减小了75.9%。为了验证有限元分析结果，基于已有的DSWFFSM原型进行了实验分析。
