する。The primary side is made as follows. As shown in FIG. 6, a plurality of comb-shaped iron plates (silicon steel plates) 3 each having a U-shaped groove 1 and a coil insertion groove 2 are laminated to have the same shape as the comb-shaped iron plate 3 and the thickness t 1 = 0 of the comb-shaped iron plate 3. The pair of end plates 4 having a thickness t 2 which is thicker than 0.5 mm is clamped and aligned by a stacking jig (not shown) and pressed. Next, as shown in FIG. 8, the double screw bolt 5 is inserted into the U-shaped groove 1 and the double screw bolt 5 is welded to the comb-shaped iron plate 3 and the end plate 4. Next, as shown in FIG. 5, the mounting bracket 6 is attached by inserting the both screw bolts 5 into the holes of the pair of mounting brackets 6 having an L-shaped cross section and tightening the nut 7. Finally, the coil 8 is inserted into the coil insertion groove 2.

である。Here, the double-screw bolt 5 is arranged on the upper side of the primary side for the following reason. If both screw bolts 5 are placed in the central portion in the direction of the short side on the primary side and at a position where the magnetic flux density is large, a current is generated by the magnetic flux, the both screw bolts 5 generate heat, and the bolts 5 thermally expand. This is because the nut 7 is loosened and the characteristics of the linear motor deteriorate.

ない。However, when the welding jig is removed after the comb-shaped iron plate 3 and the end plate 4 are welded to both screw bolts 5, the lower part on the primary side in FIG. It opens as shown in 9. Since the tightening pressure is not sufficient, noise and vibration are generated when the linear motor is operated. When the mounting bracket 6 is mounted in the state shown in FIG. 9, the pair of mounting brackets 6 are closed as shown by the chain double-dashed line, and the accuracy in mounting the primary side to the vehicle cannot be obtained.

Since the thickness of the laminated comb-shaped iron plates 3 and the like varies in the length direction, the plain washer-like liner 11 is interposed by actual matching.

Occurs, and machining of the gap surface between the secondary side and the mounting reference surface is required.

Since the comb-shaped iron plates 3 and the like are bound by screwing the nuts 7 into the insulative double-threaded screw bolts 5 arranged at the substantially central portion of the comb-shaped iron plates 3 and the like in the direction of the short side, the double-threaded screw bolts 5 are welded to the comb-shaped iron plate 3 and the like. You don't have to. Since the comb-shaped iron plate 3 and the like are tightened at the substantially central portion in the direction of the short side,
Opening of the comb-shaped iron plate 3 unlike the conventional case does not occur, and electromagnetic noise and vibration do not occur even when the linear motor is operated.

When 7 is rotated, the outside air sucked from the not-shown notch portion of the fan cover 18 is blown onto the upper surface of the comb-shaped iron plate 3 through the intake hole 16a and the ventilation hole 14a, while the ventilation hole 6
It is sprayed on the coil 8 via a and the guide plate 24,
It is discharged into the atmosphere through the exhaust hole 15a.

対して強くなる。When a horizontal load is applied to the primary side 21, conventionally, the length of the moment arm is determined by the mounting bracket 6.
However, in the present invention, the portion supported by the reinforcing plate 14 becomes the center of the moment, and the length of the arm is about half that of the conventional one. It becomes stronger against.

(A). This is the reinforcing plate 14 for the mounting bracket 6.
The angle of is not a right angle but an angle. Since the strength against the force received from the horizontal direction does not change even if it is slanted, by diagonally welding the reinforcing plate to the mounting member 6, the wind sent from above to below is guided by the reinforcing plate 14 and passes through the ventilation holes 6a. This is to allow the smooth flow to the coil 8.
【００２２】一方、櫛形鉄板３の上面へ風を送るための
通風孔１４ａは実施例１と同様にして設けられている。On the other hand, ventilation holes 14a for sending air to the upper surface of the comb-shaped iron plate 3 are provided in the same manner as in the first embodiment.

板３の上面を冷却する。In the linear motor having such a structure, when the air blown downward from the cooling fan 17 collides with the reinforcing plate 14,
The wind is guided by the reinforcing plate 14 and passes through the ventilation holes 6a, and is guided by the guide plate 24 to cool the coil 8. On the other hand, the wind that has passed through the ventilation holes 14 a without colliding with the reinforcing plate 14 cools the upper surface of the comb-shaped iron plate 3.

That is, the length of the reinforcing plate 14 is reduced to about half that of FIG. 3A, and the reinforcing plates 14 are welded diagonally to the inside of the left and right mounting brackets 6, respectively, and the notches 14b are formed at the portions where the reinforcing plates 14 are butted. A pair of notches 14b are formed so that a substantially circular ventilation hole is formed.

When the linear motor is operated, the comb-shaped iron plates do not open and electromagnetic noise or vibration is generated unlike the conventional case.
