形成される。[0003] The linear motor is largely divided into a primary core 1 and a secondary conductor 2, and has a long secondary structure in which the secondary side is longer than the primary side. The secondary side serves as a stator, and the primary side serves as a traveling element, and an air gap 3 is formed therebetween.

It is sandwiched between a pair of flanges 6 and connected with a plurality of through bolts 7 and nuts (not shown). A wheel 12 is rotatably provided in the flange 6. The core plate 4 is formed in a comb shape having teeth 4a by providing a plurality of slots 8 in the length direction. A coil 9 surrounding the secondary conductor 2 is accommodated in the slot 8.

ため、接続部の強度が低下する虞れがある。However, it is necessary to use three types of connecting plates bent in a complicated shape for connecting the lead portions of the coil, and the bending operation is troublesome since the bending must be performed manually. It is complicated. In addition, since both ends of the connection plate must be soldered to the lead-out part, work is necessary because the lead-out part and the connection plate need to be pre-soldered and the joining surfaces of both must be in contact with no gap. However, it is troublesome and a lot of time is required for soldering in one place. Furthermore, when the linear motor is operated for a long time, the temperature of the coil rises and the solder approaches the melting point temperature, so that the strength of the connecting portion may be reduced.

Further, since the connecting conductor has a U-shape and has bent portions at both ends, the connection between the lead portion of the coil and the connecting conductor can be performed by crimping using a crimping tool. Therefore, the connection operation can be performed in a short time. On the other hand, even if the temperature of the outlet rises by operating the linear motor for a long time,

が現実には複数回巻かれている。Here, although the winding directions of the coils of the respective phases are the same and current must flow in the same rotational direction, they extend in an oblique direction as shown in FIG. 4B. Since only the connecting plate extending in the left-right direction in the drawing is used without using the connecting plate 14b, as shown by a two-dot chain line, one of the coil 13 in each phase has the other lead 13 Are radially guided with respect to the coil 9 before turning, and radially guided after turning (or a similar state can be obtained by changing the bending angle of the lead portion 13).

に変えたものである。The above-mentioned two types of coils 9 are used in each phase. For example, adjacent U-phases and U-phases are arranged with the left and right coils 9 reversed. This is the same for the coils of the other phases. As a result, the position of the outlet 13 in the circumferential direction is changed for each phase using two types of coils.

The reason why both ends are bent to form a U-shape is to press-connect the lead portion 13 and both ends of the connection plate using a crimping tool. The bending at both ends can be performed mechanically by punching with a press or the like. The ends of these connecting plates and the outlet 1
As shown in FIG. 2 (b), they are connected by crimping together with a pipe-shaped crimping member 16 covering both of these members.

続を行うことができる。Next, the operation of the linear motor will be described. FIG. 2A shows how to connect the outlet 13 of each coil 9 to the end of the connection plate. Since the outlet 13 protrudes in the radial direction from the outer peripheral portion of the coil 9, FIG.
As shown in FIG. 2 (b), one crimping member 16 is placed over the lead portion 13 and, for example, the end of the connection plate 15b, and as shown in FIG.
By pressing the crimping member 16 between these members and crimping these three members, the lead portion 13 and the connection plate 15b are joined. As shown in FIG. 2 (a), the socket 18 of the crimping tool 17 can be inserted from above or below in the figure to connect all the outlets 13.

According to the linear motor according to the above, since the lead portions of the same phase at the same position in the circumferential direction are connected to each other, it is not necessary to manually bend the connection conductor into a complicated shape, and the assembling work is easy, The shape of both ends of the U-shaped connection conductor can be easily formed by machining. In addition,
Since the connection conductor and the connection conductor are joined by crimping, there is no need for soldering as in the related art, so that labor can be saved and the assembly time of the linear motor can be reduced. In addition, unlike soldering, which is a manual operation, which tends to cause individual differences in the finish, the crimping operation is performed mechanically, so that the quality after the finish is uniform.
