Background
The stator of the linear motor is a structure formed by sequentially bonding magnets with the same size on a yoke plate with a certain gap, and the conventional stator of the linear motor generally takes the length (less than two-three hundred millimeters) which is even times of the pole pitch (the width of the magnet plus the gap between the two magnets) as the standard of an enterprise. Because the yoke plate of the stator is thinner, usually four or five millimeters thick, and the flatness requirement is higher; when the length of the magnetic yoke plate is too long, the magnetic yoke plate is easy to deform during processing, so that the long-stroke motor stator is formed by splicing a plurality of standard stators. Due to the processing errors of the magnets and the yoke plates and the assembly errors of the magnets, gaps between the magnets and the magnets at the splicing positions of the stators are uneven, so that the consistency of a magnetic field is influenced, ripple force is formed, the displacement fluctuation of a motor in the operation process is caused, and the stability of system motion is influenced. The conventional solution is to improve the processing precision of the yoke plate, the magnet and the stator assembling clamp, so that the manufacturing cost is greatly increased, the error can be reduced to a certain degree, and the spliced ripple force is still large.
