Problems solved by technology
Due to the processing error of the magnet and the yoke plate and the assembly error of the magnet, the gap between the magnet and the magnet at the stator splicing will be uneven, which will affect the consistency of the magnetic field and form a ripple force, resulting in displacement fluctuations during the operation of the motor. Affects the stability of the system motion
The existing conventional solution is to improve the processing accuracy of the yoke plate, magnet and stator assembly fixture. This method not only greatly increases the manufacturing cost, but also can only reduce the error to a certain extent. still strong

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] see figure 1 , is the stator part of the linear motor structure, including the yoke plate 1 and the magnet 2. Due to the processing error of the magnet and the yoke plate and the assembly error of the magnet, the gap between the magnet and the magnet at the stator splicing will be uneven, which will affect the consistency of the magnetic field and form a ripple force, resulting in displacement fluctuations during the operation of the motor. Affects the stability of the system motion. see figure 2 , is a preferred embodiment, using fixture assembly to manufacture the stator part. When making the stator of the linear motor through the process of splicing the stator of the linear motor according to the present invention, at first the yoke plate 1 is fixed on the base plate 3 with screws, so that the two yoke plates 1 are tightly spliced togeth...

The invention discloses a linear motor stator splicing process which is characterized by comprising the following steps: 1, splicing two or more than two magnet yoke plates together; 2, sequentially and uniformly bonding a plurality of magnets on surfaces of the various magnet yoke plates to form stators by virtue of glue; positioning adjacent magnets by virtue of spacing strips to enable the clearance between the adjacent magnets to be consistent before bonding the magnets by virtue of the glue; 3, marking numbers for the made stators according to a manufacturing sequence; sequentially assembling according to the numbers in the linear motor stator assembling process. According to the splicing process disclosed by the invention, the consistency of the magnets and the magnet clearances at stator splicing joints can be ensured, the non-uniformity of the magnetic field of the spliced stators is reduced, the operating stability of the system is improved, and the manufacturing cost is greatly reduced.
Description
technical field [0001] The invention relates to the field of linear motors, in particular to a process for splicing stators of linear motors. Background technique [0002] The stator of a linear motor refers to a structure in which magnets of the same size are sequentially bonded to the yoke plate with a certain gap. ) the length of even multiples (below two to three hundred millimeters) as the standard of the enterprise. Because the yoke plate of the stator is relatively thin, usually four or five millimeters thick, and the flatness requirements are relatively high; when the length of the yoke plate is too long, it is easy to deform during processing, so when making a long-stroke motor stator, several standards are used. The stator is spliced together. Due to the processing error of the magnet and the yoke plate and the assembly error of the magnet, the gap between the magnet and the magnet at the stator splicing will be uneven, which will affect the consistency of the ...
