Hereinafter, the manufacturing process of the stator core will be described in detail with reference to FIGS. 3 to 5C.

First, a punch molding process for manufacturing the stator 30 is performed (S101).

As shown in FIG. 4A, at least one pair of segment cores 30a and 30b is formed by pressing the teeth C of the unit cores 30a 1 to 30a 9 to each other in a strip-shaped magnetic steel sheet S. FIG. It is separated from the magnetic steel sheet (S) through processing.

Here, the segment cores 30a are connected to each other through a movable connection part B, which can be machined in the form of a stator core for each of the nine unit cores 30a 1 to 30a 9 . At this time, the unit cores 30a 1 to 30a 9 form an I-shape. The upper slots in the drawing are connected to each other through the adjacent unit core and the movable connection part B, and the lower slots in the drawing are opposed to the rotor.

In particular, the stopper function B1 is further punched into the movable connection part B to prevent the bending out of the circle at the inner portion that is bent in a circle (see FIG. 4B).

In this manner, the segment cores 30a are configured as part of the stator core by connecting the nine unit cores 30a 1 to 30a 9 with each other through the movable connection part B. As shown in FIG. Here, three segment cores 30a to 30c are connected to each other to form a stator core.

Specifically, the segment core 30a is a form in which nine unit cores 30a 1 to 30a 9 are spread out on a straight line and correspond to one third of the stator core. In addition, the segment core 30a has a structure in which one unit C is connected to each of the nine unit cores 30a 1 to 30a 9 to form a body and has one tooth C for each unit core 30a 1 to 30a 9 . .

In particular, the segment core 30a is connected to the teeth C through the connection by the movable connection B, which can determine the direction of the teeth C of the nine unit cores 30a 1 to 30a 9 inward or outward. Inner rotor method for placing the rotor inside toward the inside or (C) can be selectively implemented in the outer rotor (outer rotor) method to the outside toward the tooth (C). Here, the movable connection portion (B) is formed to a thickness of about 0.1mm ~ 1mm so that even if there is a movement of the unit core (30a 1 to 30a 9 ) in the stator core manufacturing to be able to have a desired shape without cutting.

Meanwhile, in the present invention, the teeth C of the segment cores 30a are alternately disposed to face each other with the teeth C of the other segment cores 30b, thereby simultaneously punching at least one pair of the segment cores 30a and 30b. It can be molded. This can contribute to maximizing core material yield (minimizing loss), minimizing mold investment cost due to the enlargement of mold, and improving core productivity.

Next, an insert molding process for the segment core 30a in the form of an assembly through lamination is performed on a plurality of segment core thin plates (for example, 40 sheets) (S102).

As shown in FIG. 4B, the segment core 30a is integrally assembled with the bobbin 31 through insert molding using a thermosetting resin.

Specifically, the bobbin 31 made of an insulating material is coupled to the outer circumference of each of the nine unit cores 30a 1 to 30a 9 .

Is made of.

The first and second flanges 31b and 31c are formed in different sizes according to the lengths of the upper side and the lower side of the unit cores 30a 1 to 30a 9 , in particular the first flange 31b has the movable connection portion B. ) Without being covered, so that the movable connection part B can be maintained.

The segment core 30a may be subjected to a batch insert molding process for nine unit cores 30a 1 to 30c 9 in a straight line, thereby simplifying a process and minimizing mold investment. On the other hand, in the case of divided cores, the insert molding process is performed on each of the cores, which is complicated and time consuming.

Next, the winding and the connection process for the insert molded segment core 30a is performed (S103).

As shown in FIG. 4C, when the three-phase driving method of U, V, and W is applied, the segment core 30a is divided into U, N, and N for the nine unit cores 30a 1 to 30c 9 by a conventional three-axis winding machine. Coils L1, L2, and L3 are wound at the same time for each of the V and W phases. That is, in the case where coils L1, L2, L3 correspond to each of the U, V, and W phases, the coils of the U phase are continuously wound on the first, fourth, and seventh unit cores 30a 1 , 30a 4 , 30a 7 , and V Coils of phase are continuously wound on the second, fifth and eighth unit cores 30a 2 , 30a 5 , 30a 8 , and coils of the phase W are continuously wound on the third, sixth and ninth unit cores 30a 3 , 30a 6 , 30a 9 . . As such, since the segment core 30a is wound simultaneously on the U, V, and W phases, the winding operation is simple and the winding time is reduced to minimize the coil short wire.

Here, the winding operation is performed as described above with respect to the segment cores 30b and 30c other than the segment core 30a and then connected to each other with respect to the coil.

Then, the core connection process for the three segment core (30a to 30c) winding is completed is performed (S104).

As shown in FIG. 4D, the three segment cores 30a to 30c are arranged in a circle using a jig and then connected to each other to form a stator 30. In this case, when the three segment cores 30a to 30c are disposed in a circle, the three segment cores 30a to 30c may maintain the circle without being bent inward out of the circle by the stopper function portion B1.

In addition, the segment core 30a forms a core coupling portion D at both ends (that is, the first unit core 30a 1 and the ninth unit core 30a 9 ), and the core coupling portion D is U-shaped. It is punched out according to the coupling method by the pin coupling method (refer FIG. 5A), the rivet coupling method (refer FIG. 5B), the groove coupling method (refer FIG. 5C), etc. Here, the core coupling part D is not illustrated in FIGS. 3A to 3C for convenience of description, but is actually formed in the segment cores 30a to 30c according to the coupling method.

In addition, the segment cores 30a may be connected to each other in a manner of combining a pin coupling method and a groove coupling method in a state of being stacked in an assembly. To this end, one end of the single segment core (30a) is extended to form a coupling portion (E), the coupling portion (E) is punched through the through hole (E1) of the pin or rivet for the assembly of the assembly is punched out (See FIG. 5D). Subsequently, the segment cores 30a are stacked to form the concave portion E2 on one side and the convex portion E3 on the other side (see FIG. 5E) when stacked into an assembly, and thus, a pair of assembly segment cores 30a Is contacted through the recess coupling of the concave portion E and the convex portion E3, and then is coupled by pins or rivets through the through hole E1 (see FIG. 5F).

In particular, the stator 30 of the present invention may be selectively implemented for the inner rotor or the outer rotor according to the connection method of the three segment cores (30a to 30c).

As described above, the stator 30 of the present invention is an inner case in which the rotor is disposed inward in the direction of the teeth C in the unit cores 30a 1 to 30c 9 of the segment cores 30a to 30c.
