Description

technical field [0001] The invention belongs to the field of motors and relates to a linear reluctance motor structure. Background technique [0002] The structure of the existing unilateral flat linear permanent magnet synchronous motor is as follows: Figure 19 shown. The motor is composed of a primary and a secondary. The primary is mainly composed of an armature core and an armature winding, and the secondary is mainly composed of a permanent magnet and a magnetic yoke. The armature magnetic field generated by the energization of the armature winding interacts with the magnetic field of the secondary permanent magnet to generate electromagnetic force, which acts on the mover to drive the mover to move in a straight line. The advantages of this type of linear motor are simple control, good dynamic characteristics, high thrust linearity, simple primary structure, and convenient processing and manufacturing. However, this type of motor has a big disadvantage that the perm...
