Embodiment 1
[0057] A modular secondary yokeless bilateral primary permanent magnet switched reluctance linear motor of the present invention see figure 1 , including bilateral primary 11 and secondary 10, and there is an air gap between the primary 11 and secondary 10. The primary 11 is composed of primary modules 110, each of which includes a U-shaped magnetically permeable material 111, an armature winding 112, and a permanent magnet 113 placed at the notch of the U-shaped magnetically permeable material 111, and the secondary 10 is composed of Several secondary mover blocks 100 without yoke are formed. The armature windings 112 in the same primary module 110 have opposite winding directions and belong to the same phase. The permanent magnets 113 are magnetized horizontally, the magnetization directions of adjacent permanent magnets 113 are the same, the magnetization directions of the corresponding permanent magnets 113 above and below the primary 11 are opposite, and the magnetic flu...
