Description

一种铁心磁路复用冗余功率驱动系统
本申请要求于2021年2月4日提交至中国专利局、申请号为202110154340.X、发明名称为“一种铁心磁路复用冗余功率驱动系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及电气传动自动化领域，特别是涉及一种铁心磁路复用冗余功率驱动系统。
背景技术
直线电机驱动技术至诞生发展至今已越来越成熟，它以精度高、无磨损、噪音低、效率高、响应快、节省空间等优点使其在各领域应用广泛，直线电机在民用、工业、军事等行业中都得到广泛应用。大功率直线电机变频驱动是涉及电力电子、电机、电力拖动及自动化等多个学科领域的高新技术，大功率直线电机和变频驱动系统是现代轨道交通、能源矿业、航空航天和国防军工等领域国家多个重点工程的关键设备。
在交通运输行业中，上海磁浮线采用的长定子同步直线电机驱动，速度可达500km/h，甚至更高。但是受功率器件电压电流限制，目前国内变流器单台最大容量有限，即使采用分段式双端供电，也就是说由两台大功率变流器同时给一个长定子段供电，最大功率也是受限制的，因而磁浮列车最高速度也受到驱动系统容量限制。
西安交通大学侯立军的博士论文《多相感应电机变频调速系统的研究》中提到一种六相电机电路，由电源、六相变流器和六相电机组成，拓扑结构的特点是单台变流器驱动单台电机。IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS.VOL.55,NO论文《Multiphase Electric Machines for Variable-Speed Applications》中提到一种n相电机驱动系统，由一台n相逆变器和一台n相电机组成，拓扑结构特点仍然是单台变流器驱动单台电机。
可见，无论是上海磁浮线采用两台大功率变流器同时给一个长定子段 供电，还是以上两篇论文采用单台变流器驱动单台电机，都受到了变流器功率的限制，使得驱动系统的最大功率受到限制，无法满足驱动系统的超大功率需求；并且单个变流器出现故障就会影响到对应电机，无法满足驱动系统的冗余需求。

主推旋转电机和侧推旋转电机将电功率转换为机械功率，使得船舶的 螺旋桨转动，从而推动船舶运动，而直线电机是将电功率转换为直线运动的动能。
(三)、应用于纯电飞机推进系统；
如图8所示，铁心磁路复用电机为m组n相旋转电机，m为大于等于2的正整数，n为大于等于3的正整数，铁心磁路复用电机具有m组n相电机绕组；
