Embodiment
Below, by accompanying drawing is described, the embodiment that smallpox imbeds shape ventilation fan is applied to the present invention and is described.
Fig. 1 is the stereogram of the air-supply arrangement using motor of the present invention, and Fig. 2 is the profile of the air-supply arrangement using motor of the present invention.
As shown in Figure 1 and Figure 2, body frame 1 is slightly rectangle.Framework 1 is provided with air inlet 6 below, and outer peripheral face is provided with exhaust outlet 3, is integrally formed respectively by synthetic resin.The end face 2 of this body frame 1 is that metallic plate is formed, and its central portion is provided with through hole.And be provided with centrifugal flabellum 5 in above-mentioned body frame 1, the lower end of the rotating shaft 14 of its central shaft and motor 4 connects, and centrifugal flabellum 5 is reliably connected with the lower end of this rotating shaft 14, but can as required can free demolition, installation.Setting 7 in motor 4.
At this, motor 4 of the present invention is described in detail.As shown in Figure 3, the rotating shaft 14 of motor 4 above and be provided with axle supporting seat 16 below, rotor 13 is fixed on rotating shaft 14 part between described above and below axle supporting seat 16.Centrifugal flabellum 5 is fixed on one end of this rotating shaft 14.
In addition, be spaced a distance in the peripheral direction of rotor 13 stator 7 is set.And stator 7 is built in and is fixed in shell A17 and shell B18.
Again the stator 7 of motor 4 of the present invention is described below.As shown in Fig. 3 ~ Fig. 7, stator core 8 is split into the teeth portion 20 that forms magnetic pole and is connected at peripheral part with this teeth portion 20 and forms the yoke portion 19 of magnetic circuit, is respectively a stator number and is laminated.Insulator 9 is made of one piece with resin etc. by inner wall part 24, winding section 25 and outside wall portions 26.And, after this insulator 9 is mounted to teeth portion 20, then the winding 10 that reels.The core of 26a on the outer wall of insulator 9 outside wall portions 26, contact pin 11 is uprightly set, and, in the both sides of the circumferencial direction of this contact pin 11, from winding section 25 to peripheral direction, and from 26a above outer wall to the direction of teeth portion 20 formed coiling introduce recess 30.That is, this plays coiling to introduce recess 30 is grooves that the top of the stacked direction of stator core 8 from outside wall portions 26 is formed to stacked direction.Further, be provided with and cover the outer wall insulation wall 31 that this plays a part for coiling introducing recess 30, this outer wall insulation wall 31 is extended to outer wall end face 26b direction.And, in the both sides of the circumferencial direction of the inner wall part 24 of insulator 9, from winding section 25 to inner peripheral surface direction, and formed line introducing recess 32 from 24a above the inwall of inner wall part 24 to the direction of teeth portion 20.This crosses line, and to introduce recess 32 be outer circumferential side at inner wall part 24, the groove that the stacked direction from its top to stator core 8 is formed.And, be provided with and cover the inner wall insulation wall 33 that this crosses a part for line introducing recess 32, this inner wall insulation wall 33 is extended to inner wall end surface 24b direction, and, by the height of this inner wall insulation wall 33 is set to identical with the height of 24a above inwall, formed line guiding groove 27, thus final formation stator 7.
Following again, the manufacture method of stator 7 is described.As shown in Figure 4,4 teeth portion 20 that insulator 9 is housed are configured, make wherein to be formed centrally rotor hole 28.Now, there are 4 yoke portions 19 as shown in Figure 4, before carrying out coiling, do not connect between 4 yoke portions 19 and adjacent teeth portion 20, form the state that teeth portion 20 can carry out coiling.As the winding sequence of winding, first, the coiling of winding B phase the 1st winding 10c, the coiling of B phase the 2nd winding 10d that and then reels.In addition, in this embodiment, be arranged on because line crossed by B phase the 1st winding 10c and the relaying of B phase the 2nd winding 10d and illustrate relative face, so not shown in the figures, after the winding B phase winding coiling of detailed winding completes, the mode of next winding A phase winding coiling is described.As shown in Figure 5, the coiling of A phase the 1st winding 10a, from contact pin 11, will play coiling 21 and guide to coiling introducing recess 30, then complete the coiling of A phase the 1st winding 10a.Next, by cross line 23 (not shown) shift to A phase the 2nd winding 10b carry out coiling time, as shown in Figure 6, cross the inner wall part 24 of line 23 along B phase the 1st winding 10c place of coiling, passed line guiding groove 27, as shown in Fig. 3, Fig. 4, Fig. 7, after being directed to the introducing of the line excessively recess 32 at A phase the 2nd winding 10b place, complete the coiling of A phase the 2nd winding 10b again, whole coiling 22 is connected with final contact pin 11e.After the coiling of each like this phase winding completes, yoke portion 19 is connected with teeth portion 20, makes stator core 8 integration, a plurality of contact pins 11 is arranged to the circuit board 12 of fixed electric wiring, thus complete the manufacture of stator 7.
The stator 7 of picture said structure, the both sides of the circumferencial direction of the contact pin 11 in the outside wall portions 26 being uprightly arranged at insulator 9, have been provided with coiling and have introduced recess 30.Therefore, coiling coiling direction as shown in the Examples or the coiling direction contrary with it can be easy to realize, and can adapt to different motor (such as, the direction of rotation of rotor is not equal).
In addition, because introduce recess 30 in a coiling to be provided with outer wall insulation wall 31, playing a coiling 21 can be completely isolated with A phase the 1st winding 10a, can not cause harmful effect, can improve quality and the reliability of motor to copper cash paint film.
In addition, the both sides due to the circumferencial direction of the inner wall part 24 at insulator 9 were provided with line and introduced recess 32, and coiling coiling direction as shown in the Examples or the coiling direction contrary with it can be easy to realize, and can adapt to different motor.
In addition, introduce recess 32 at mistake line and be provided with inner wall insulation wall 33, crossing line 23 can be completely isolated with A phase the 2nd winding 10b, can not cause harmful effect, can improve quality and the reliability of motor to copper cash paint film.
And, because play coiling to introduce the both sides that recess 30 is arranged at the circumferencial direction of contact pin, cross line and introduce the both sides that recess 32 is arranged at the circumferencial direction of inner wall part 24, so, even if change the direction of winding of winding, the configuration of contact pin 11 and sharing of electric wiring circuit board 12 also can be realized.
In addition, owing to forming line guiding groove 27 at inner wall part 24, crossed line 23 positively fastened, and can avoid contacting with the coiling of other phase, thus also can improve quality and the reliability of motor.
In addition, the stator core 8 of the present embodiment is divided into 4 teeth portion 20 and 4 yoke portions 19, when the number of poles according to motor, when changing mode or the Segmentation Number of segmentation, its action effect is also identical, generally speaking, as long as directly coiling can be wound on the structure be installed on the insulator of stator core can.
In addition, the present embodiment is the structure by being arranged on teeth portion 20 by shaping insulators 9 such as resins, but if each teeth portion is accommodated in mould, the structure be formed in one with insulator, or using the structure etc. of teeth portion installing insulating body of the insulating material such as part glued membrane, its action effect is also identical, generally speaking, as long as the structure of the insulator outside wall portions or inner wall part with fastening coiling can.
Owing to having high-quality, high reliability, this motor being provided with above-mentioned stator can be widely used in the various electric equipments such as air-supply arrangement.
