本発明はリニアパルスモータの可動子の製造方法に関す

されている。As shown in FIG. 4, the conventional method for forming iron core magnetic pole teeth of a linear pulse motor mover is to form parallel cutting grooves 13 in a magnetic thin plate 11 with a cutter, and to cut the portion between adjacent cutting grooves. Alternatively, as shown in FIG. 5, parallel grooves 23 may be formed by etching on the magnetic thin plate 21 by photolithography, and the portion between them may be used as the magnetic pole teeth 22. The methods used are adopted.

欠けるという問題がある。The conventional method of forming the iron core magnetic pole teeth of the mover of a linear pulse motor as described above is to form a large number of cutting grooves by machining with a cutter, but the width of the cutting groove changes due to wear of the cutter. There is a drawback that the width of the magnetic pole teeth changes, and there are also problems that the durability of the cutter is short and the machining time is long. On the other hand, with the latter method of etching, there is no problem with the dimensional accuracy of the magnetic pole teeth, but there is a problem that it lacks mass productivity because it requires many steps for etching, such as masking and exposure before and after etching. .

子を得ることができる。As shown in Figures 1 to 3, a thin magnetic plate 1 is plastically worked using a mold to form concave portions 3 and convex portions 2 alternately in parallel, and the tips of the convex portions 2 have an irregular shape. The irregular portion 2a is formed as an irregular portion 2a, and the base portion following it is a straight portion 2b having a constant thickness.The irregular portion 2a is removed by machining such as grinding or cutting to form a magnetic pole tooth surface 2C with a flat surface. As a result, it is possible to obtain a movable element in which the thickness of the magnetic pole teeth is constant and is excellent in mass production.

が得られるという効果がある。As explained above, in the method of manufacturing a mover for a linear pulse motor of the present invention, a thin magnetic plate is plastically worked to form convex portions and concave portions parallel to each other, and the tip of the convex portion corresponding to the magnetic pole tooth portion is The magnetic pole tooth surface is formed by removing the irregularly shaped part by machining, so even if there is an error in the cutting allowance due to machining, the thickness of the straight part following the irregularly shaped part is constant. This has the effect of making it possible to obtain products of stable quality by keeping the thickness of the magnetic pole teeth constant.Also, regarding the durability of the mold for plastic working, the side used as the mover of the magnetic thin plate Since machining is applied to the surface of the mold, material relief during plastic processing can be taken into irregularly shaped parts, and therefore, abnormal pressure on the mold teeth due to variations in material thickness or variations in mold stroke can be avoided. Since there is no generation, excellent durability can be obtained, and therefore a manufacturing method with excellent mass productivity can be obtained.
