【摘要】：基于12/8极双通道开关磁阻电动机(dual-channel switched reluctance motor,DCSRM)和传统SRM的有限元模型,分别计算两种电机的自感、互感、转矩特性,并对比分析计算结果。为了更加深入研究该两种电机的性能,在已建立有限元模型的基础上,采用磁路电路联合仿真建模法,分别建立两种电机的动态仿真模型,并对比分析了两种电机的可靠性和转矩脉动。经过有限元仿真和电路磁路联合仿真,结果表明:传统SRM互感较小,可忽略互感对电机的影响,而DCSRM的互感较大,对电磁转矩的输出的影响较大。DCSRM能够实现单通道容错运行,提高了电机的可靠性。此外,经分析动态仿真结果表明,选择合适的控制策略,DCSRM的转矩脉动比传统SRM小。
[Abstract]:Based on the finite element model of dual-channel switched reluctance motor and traditional SRM, the self-inductance, mutual inductance and torque characteristics of the two kinds of motors are calculated, and the results are compared and analyzed. Based on the established finite element model, the dynamic simulation models of two kinds of motors are established by using the combined simulation modeling method of magnetic circuit. The reliability and torque ripple of the two kinds of motors are compared and analyzed. The results of finite element simulation and circuit magnetic circuit simulation show that the mutual inductance of traditional SRM is small and the influence of mutual inductance on motor can be ignored, but the mutual inductance of DCSRM is larger. DCSRM has a great influence on the output of electromagnetic torque. DCSRM can realize single channel fault-tolerant operation and improve the reliability of motor. In addition, the dynamic simulation results show that the torque ripple of DCSRM with suitable control strategy is smaller than that of traditional SRM.
