The insulating layer in face.Moreover, in stator core 2, the coiling 5 of U phases, V phases, W phases this three-phases is equipped with across insulating part 3.That is, coiling
5 are arranged in the outside of stator core 2.It is provided with as the insulation from 3 protruding portion outstanding of insulating part in the peripheral part of insulating part 3
Part terminal base 11.In insulating part terminal base 11, it is equidistantly provided with terminal pins 6.It is wound with coiling end 5a in terminal pins 6.
Fig. 2 is the stereogram of embodiments of the present invention being fixed on circuit board before the insulating part of motor.Such as Fig. 2
It is shown, in insulating part 3, there is circular circuit board 4 from axial restraint in the end face of a side of the stacking direction of stator core 2.
Near the peripheral part of circuit board 4, there are three through holes 12 for setting.Through hole 12 is set in fixed insulating part 3 and circuit
The position on the top of terminal pins 6 is abutted when substrate 4.In addition, through hole 12 be wound with coiling end 5a each terminal pins 6 it is equal
Can by size.
In addition, in circuit board 4 and 2 opposite side of stator core face, it is provided with conductive pattern portion（It is not shown）.
After stator core 2 winds the coiling 5 of three-phase, several enclose the land is wrapped in the position being located most closely to the coiling end 5a of three-phase respectively
Terminal pins 6.Moreover, circuit board 4 is fixed on insulating part 3, while the terminal pins 6 of three-phase are by through hole 12, coiling end 5a,
The conductive pattern portion of terminal pins 6 and circuit board 4 is electrically connected by the solder 14 of Fig. 1.
In this state, stator core 2, insulating part 3, coiling 5 and circuit board 4 are installed on mold, thermosetting resin
It is injected, to shape the molding body 7 of Fig. 1.Herein, molding body 7 shown in FIG. 1 is in 4 part of circuit board, with it is flange shape with
Direction orthogonal rotary shaft 9a is stretched out.In the flange portion, it is provided with the threaded hole for fixed motor 1（It is not shown）.This
Sample, stator core 2, insulating part 3, coiling 5 and circuit board 4 mold integration by formation molding body 7 by resin, become stator
8。
As shown in Figure 1, stator 8 is that the central part of the stacking direction of stator core 2 is provided with the concave shape of opening portion 8a.
From opening portion 8a, it is inserted into the rotor 9 rotated freely by bearing 10, stator 8 is kept fixed with bearing 10.Herein, 10 quilt of bearing
It is pressed into rotary shaft 9a.Rotary body 9b is set to the inner circumferential side of stator 8, constitutes the interior motor 1 to make the transition.
Fig. 3 is the partial cross-sectional view of the motor of embodiments of the present invention.As shown in figure 3, insulating part 3 be provided with from
The inclined-plane of the side of the coiling 5 in the outside of stator core 2 to the side of the stator core 2 of through hole 12（slope）13.
Fig. 4 is the vertical view before the molding of the motor of embodiments of the present invention.As shown in figure 4, inclined-plane upper end 15 exists
When the insulating part 3 of Fig. 3 is fixed with circuit board 4, it is set to the following location directly of through hole 12.In addition, terminal pins 6 are uprightly set
It is placed near inclined-plane upper end 15.Moreover, coiling 5, after 13 cabling of inclined-plane, coiling end 5a is wound in each terminal pins 6.
In addition, as shown in figure 3, insulating part 3 is fixed the terminal pins 6 for being wound with coiling end 5a simultaneously with circuit board 4
Pass through through hole 12.Moreover, the conductive pattern portion of coiling end 5a, terminal pins 6 and circuit board 4 are electrically connected by solder 14.
When circuit board 4 is fixed on insulating part 3 shown in Fig. 3, inclined-plane 13 and the first distance 16 of 12 end of through hole are more than with void
The second distance 17 of the upper end 11a and 12 end of through hole of insulating part terminal base 11 when what line indicated is not arranged inclined-plane 13.This
Sample, by be arranged inclined-plane 13, when circuit board 4 is fixed on insulating part 3, the edge of through hole 12 and gone to terminal pins 6 around
Line 5 is difficult to contact, and effectively prevent breaking（Open circuit）.
In addition, as shown in figure 4, through hole 12 is long ellipse on the radial 4a of circular circuit board 4.Terminal pins
6 are set to the through hole center 12a than through hole 12 more by the position of the stator peripheral side 8a of stator 8.Accordingly, because through hole
12 shape is the longer ellipse on the radial 4a of circuit board 4, so 4 quilt of insulating part shown in Fig. 33 and circuit board
The first distance 16 when fixed than it is round when bigger.In this way, when insulating part 3 and circuit board 4 are fixed, the edge of through hole 12
It is difficult to contact with the coiling 5 positioned at the underface of through hole 12, effectively prevent breaking.In addition, in the present embodiment, through hole
12 shape is ellipse can also use oblong but as long as being long shape on radial 4a.
By using this structure, coiling end 5a shown in Fig. 3 is wound in terminal pins 6, so required insulating part end
Space between stroma 11 and circuit board 4 substantially reduces, can realize motor 1 slimming and air purifier it is small-sized
Change.
In addition, as shown in figure 3, being wound with each terminal pins 6 of coiling end 5a by through hole 12, so can be same
Shi Jinhang coilings end 5a, terminal pins 6 and circuit board 4 conductive pattern portion soldering（With solder 14）.Motor 1 as a result,
Assembling become simple, and then the length of terminal pins 6 can also be shortened, so cost is reduced.
