摘要
该文通过建立开关磁阻电机(SRM)的等效磁网络模型,分析了新型两相励磁控制策略(TPE)下电机的稳态特性。与传统的控制方案不同,两相励磁方案下电机自感磁链和互感磁链都是产生有效转矩的关键因素,文中详细介绍了通过求解等效磁网络模型取代计算绕组的自感和互感,来研究电机的运行特性的方法。实验结果与仿真分析结果的非常接近,证明所提出的方法是正确的。
In this paper, an equivalent magnetic circuit model of the steady state characteristics of the switched reluctance motor (SRM), under two-phase excitation, is investigated in detail. The torque is both developed by self-inductance and mutual-inductance under two-phase excitation. Based on the use of the magnetic equivalent circuit of the motor, the state equations of the model are established by taking the flux linkages of the phase windings as the state variable. The good agreement between the simulated and measured values proves that the proposed model is correct.
