Embodiment Construction
[0019] Hereinafter, the present invention will be described in more detail with examples in conjunction with the accompanying drawings:
[0020] Combine Figure 1-2 , The present invention mainly includes the first housing 1, the coil former 2, the second housing 3, the flange 4, the bearing end cover 5, the linear bearing 6, the main shaft 7, the coil winding 8, the permanent magnet 9, the elastic cylindrical pin 10, Armature 11, spring 12, nut 13.
[0021] The first housing 1, the flange 4 and the armature 11 are provided with small teeth with variable pitch and tooth width, so that better linear characteristics of displacement-electromagnetic force can be obtained. A certain size of working air gap is left between the teeth on the first housing, the flanges and the teeth on the armature.
[0022] The first shell 1, the second shell 3, the flange 4 (ie the stator) and the armature 11 (ie the mover) are all made of electrical pure iron with good magnetic permeability; the permanen...
