| 摘 要： | 与传统的12/8极开关磁阻电机不同,双通道开关磁阻电机线圈之间采用一对极绕组反向串联的结构形式,由两套独立的功率电路驱动形成新型的双通道控制系统,该系统能够实现容错控制以提高可靠性.本文在分析双通道开关磁阻电机原理和结构的基础上,建立了电机每个通道绕组的磁路等效数学模型,在一个相周期内对磁路各部分磁导进行了详细分解计算,确定了以磁导表示的磁通矩阵,推导出绕组自感及各相之间互感的计算方法.该模型考虑了电机轭部磁路和材料非线性磁饱和的影响,提高了模型的实用性.有限元分析结果验证了该数学模型的正确性.

| Abstract: | Different from the conventional 12/8 switched reluctance motors,the windings of dual channel switched reluctance motor(DCSRM) were placed in opposite series and driven by two independent sets of power electronic circuits.Thereby an electrical driven system with dual control channels was formed,and a fault tolerated operation mode could be used in this system for high reliability.After the structure and principle of DCSRM were analyzed,the mathematical model of the magnetic equivalent circuits in each channe... |
