ａとｂの差が大きくなるようにしてある。In this embodiment, the width e 1 of the groove (2a) of the small slot (2)
Is formed narrower than the width f 1 of the groove (3a) of the large slot (3), and the depth g 1 is deeper than the conventional depth g.
Width f 1 is formed to f 1 = a + b the depth of the grooves of the large slot (3) (3a) is formed on h 1. Here, a and b are the dimensions from the center line of the opening (3b) to the left and right side edges of the groove (3a). Then, the groove (2a) of the small slot (2A) adjacent to the large slot (3) is moved as close as possible to the end of the core punched plate (1) with respect to the center line of the opening (2b), so that there is a dimensional margin. The larger slot makes the center line of the groove (3a) of the large slot (3) smaller than the center line of the opening (3b).
It is arranged such that the difference between the dimensions a and b becomes larger toward the end of the iron core blank (1) by moving it toward

できる。Therefore, when the motor dimensions are not changed, the width f 1 of the groove portion (3a) and the width c of the tooth portion (4) of the large slot (3) can be increased as compared with the conventional linear motor of the same dimension. As a result, a larger amount of current can be passed than in the conventional product, the magnetic flux can be increased, and the thrust can be increased.
On the contrary, even if the motor size is reduced, the width f 1 of the groove (3a) and the width c of the tooth (4) of the large slot (3) can be made the same as the conventional product, so that the same thrust Can be obtained.

も小形にすることができる効果がある。As described above, in the present invention, the width of the first slot on both sides of the core punching plate is narrowed, and the center line of the groove portion of the second slot in the central portion is located on both sides of the core punching plate with respect to the center line of the opening. The width of the second slot and the width of the teeth can be increased because it is moved toward the direction, and the thrust can be increased with the same size. In the case of the same thrust, the linear motor can be made smaller than before. There is an effect that can be.
