摘　　要：本文提出了一种新型的分段式定子双面磁通反向永磁直线电机(SSDS-LFRPM),适合长行程应用,例如城市轨道交通、高层建筑电梯等。该电机采用外动子内定子结构,电机由两个凸齿铁心和三相电枢绕组组成,永磁体安装在动子齿表面。定子采用简单的分段式铁心设计,可显著降低定子的铁用量和电机的总成本,因此特别适合长行程应用。介绍了该电机的结构和工作原理,并结合材料使用率进行了优化设计。通过有限元分析,对该电机的材料使用、特性和性能进行了分析,并与现有的双面磁通反向永磁直线电机(DS-LFRPM)进行了比较。以一台电机样机为例,对分析模型和有限元分析结果进行了实验验证。This paper proposed a new segmental stator double-sided linear flux-reversal permanent magnet(SSDS-LFRPM) motor,which was particularly attractive for long-stroke applications.The proposed motor adopted outer-mover and inner-stator configuration,in which the mover consisted of two iron cores with salient teeth wound with three-phase armature windings and PMs mounted on the surface of mover teeth.And the stator was designed as simple segmental iron cores so that the iron material usage of stator,as well as the total cost of motor,can be reduced significantly,especially for the long-stroke applications.The configuration and operation principle of the proposed motor were presented,and the optimization design were performed considering material usage.By using the finite element analysis,the material usage,characteristics and performances of proposed motor were analyzed and compared with the existing DS-LFRPM motor.
