Abstract

Mutually coupled (MC) switched reluctance machines (SRMs) have attracted considerable interest due to their lower torque ripple and reduced vibration compared to conventional SRMs. Accurate analytical modeling of radial and tangential airgap fields is critical for the initial design and harmonic source analysis of MCSRMs. However, the conventional SRM analytical model is not suitable for predicting airgap fields of MCSRMs due to their different winding configurations. Therefore, an analytical model is proposed in this paper to predict the airgap fields of MCSRMs, in which the tangential field and nonzero time-dependent magnetomotive force (MMF) are all accounted for. The model distinguishes the effect of armature winding, as well as single- and bilateral-magnetic-salient structure, on airgap field harmonics, facilitating root cause analysis of these harmonics. Furthermore, the average torque, torque ripple, radial and tangential electromagnetic force density of MCSRMs under non-saturation condition can be quickly predicted. The model is validated with two 12 stator-slot/8 rotor-slot MCSRMs through finite element simulation and experimental test.

考虑切向场的互耦开关磁阻电机气隙场解析建模

与传统的开关磁阻电机相比，相互耦合（MC）开关磁阻电机（SRMs）由于其更低的转矩脉动和更低的振动而引起了人们的广泛关注。径向气隙场和切向气隙场的精确解析建模对于mcsrm的初始设计和谐波源分析至关重要。然而，由于mcsrm绕组结构的不同，传统的SRM分析模型不适合预测mcsrm的气隙场。为此，本文提出了一个考虑切向场和非零时相关磁动势（MMF）的mcsrm气隙场预测分析模型。该模型区分了电枢绕组以及单侧和双侧磁凸结构对气隙场谐波的影响，便于分析气隙场谐波的根本原因。此外，还可以快速预测非饱和状态下mcsrm的平均转矩、转矩脉动、径向和切向电磁力密度。采用2台12定子槽/8转子槽mcsrm进行有限元仿真和实验验证。
