A New Linear Double Salient Permanent Magnet Motor with Complementary Winding
In this paper,two novel structures of linear double salient permanent magnet (LDSPM) motor having magnets and armature windings in primary are proposed and compared.Firstly,the design principles of both motors are presented.Then,for a fair comparison,two motors are designed based on the same primary dimensions including the slot area,teeth number,pole pitch,permanent magnet volumes and coils number per phase,while the stator pole pitch and the primary structure are different.Finally,the configurations and static characteristics of both motors are critically compared based on finite element (FE) analysis.The results indicate that the proposed topology can avoid the asymmetry of back-EMF waveforms and reduce cogging force and thrust force ripple.Also,the proposed primary permanent magnet linear motors are suitable for the longer stator application such as urban rail transit (URT).
