Description
Technical field
The present invention relates to motor, relate in particular to insulating element in rotation type motor outside, be the simplification of structure of bobbin and coiler part and the raising of reliability.
Background technology
As prior art, as Patent Document 1, interior rotation type motor is circumferentially with protuberance at the tooth section front end edge of stator core, in order to amplify the tooth section face towards gap, and the closed groove dwindled by channel opening section forms.
Because of the restriction of tooth section shape, can not insert the bobbin of winding cables from outside diameter, therefore be configured to and use two bobbins to clamp tooth section.By electric wire being wound on to the tooth section of being clamped by two bobbins, bobbin forms integrated, thereby be configured to, utilizes the protuberance of tooth section front end to prevent to outside diameter discrete.
So, tooth section shape is made roughly to square column, and can be inserted the content of the stator core of the bobbin of winding cables from outer circumferential side relating to, fixing about this bobbin has no to describe in existing example.

Embodiment
Below, about embodiments of the present invention, with reference to accompanying drawing, illustrate.
Fig. 1 means the outside drawing of insulating element of the outer rotation type motor of embodiments of the present invention.Fig. 2 is illustrated in winding cables on the insulating element of outer rotation type motor of embodiments of the present invention and forms the outside drawing of the state of coil.Fig. 3 means to be arranged on the front view in stator core by the coil of winding cables on the insulating element of the outer rotation type motor of embodiments of the present invention.Fig. 4 means the front view of stator core of the outer rotation type motor of embodiments of the present invention.Fig. 5 means the enlarged drawing of claw of insulating element of the outer transition of embodiments of the present invention.Fig. 6 means the cutaway view of the outer rotation type motor of embodiments of the present invention.
In Fig. 1, bobbin 1 has hollow cylindrical body 7, is provided with the first flange 6a and the second flange 6b at its two ends.And bobbin 1 has the bobbin that stretches out to the first flange 6a side fixedly pawl 2,3 and the arm 4,5 of use.
Fig. 2 be illustrated in bobbin 1 cylindrical body 7 the part winding cables and form the situation of coil 2.Thus, the part of right that electric wire is wound into figure is thick, and left half is thin.This be because, the coil 12 of figure inserts the tooth section 14 of stator core 13 from left side, the left side of coil 12 is configured in the root portion of tooth section 14.
To narrate in the back, this is that roomy leading section multireel electric wire, narrow root are rolled up electric wire less, thereby can reel a lot of electric wires because its root of slot part surrounded by tooth section 14 is narrow, front end is roomy.
In addition, the left side of figure is positioned at the root of tooth section 14, in the left side of figure, draws electric wire, and is connected to overlap joint line 15, and this overlap joint line 15 is not shown at this.Therefore, electric wire is drawn in the space 11 of the central portion by being located at flange 6a.And plate extends to the left side of bobbin 1, is provided with in the above projection 8,9,10, utilizes these protrusion directs electric wires.
Turn back to Fig. 1, the length of the bending position of pawl 2 and arm 4 forms rightly, so that pawl 2 coincide with the arm 4 of another bobbin 1 of adjacency.
In addition, pawl 2 and arm 4 are positioned at the first surface of not shown stator core 13, and pawl 3 and arm 5 are positioned at second of not shown stator core 13.In this embodiment, pawl 2 and pawl 3 be positioned at same side, on figure for left side, therefore the outlet side of coil made identical and arranged bobbin, the position relationship of pawl 2,3 and arm 4,5 will become all identically, and must become coincideing of pawl 2,3 and arm 4,5.
Pack into the state of tooth section 14 of the bobbin 1 that Fig. 3 means to be provided with above-mentioned coil 12.In addition, Fig. 4 means the front view of stator core 13, becomes thus and has cutting apart of 8 tooth sections 14 of shape unshakable in one's determination.And, by tooth section 14, be rectangle, and stacked this stator core 13, thereby the tooth section 14 of formation square column shape.
As previously mentioned, the bobbin 1 that is provided with the described coil 12 of Fig. 2 is inserted to the state representation of this tooth section 14 at Fig. 3.That is, the coil of the front of tooth section 14 12 volumes are thick, coil 12 volumes of the root side of tooth section 14 are thin, certain thereby the space of the coil of adjacency 12 roughly keeps.
Fig. 5 amplifies the pawl 2 of expression bobbin 1 and the identical part of arm 4, the coil 12 of the state of the tooth section 14 of the stator core 13 shown in the Fig. 3 before this bobbin 1 is provided with and is inserted into.With respect to arm 4, the jut of pawl 2 is configured in the bottom of arm 4, thereby the bobbin 1 that can prevent from having arm 4 breaks away from, is that bobbin 1 and coil 12 break away from stator cores 13 to the upper direction of figure.
As said, 1 of bobbin prevents from breaking away from bobbin each other, therefore without making stator core 13 miscellaneous parts such as grade have the function that prevents from breaking away from use.And bobbin utilizes resin to make, its shape utilizes mould to make freely, therefore has the effect that this prevents that detachment function from can provide extremely easily.
In addition, stacked stator core 13 utilizes bolt 20 to fix.The projection 8,9,10 of bobbin 1 configures in the mode of surrounding this bolt 20, also plays the effect that prevents that drawn electric wire from contacting with bolt 20.
In addition, in the present embodiment, as shown in Figures 1 and 2, by pawl 2,3 be arranged on the same side, on drawing for left side, but also can be using upside, the pawl 2 of drawing electric wire side is as left side, using downside, do not draw the pawl 3 of a side of electric wire as right side.This occasion, each other, pawl must be relative with arm for the bobbin by adjacency.
In addition, by drawing the space 11 of electric wire and the projection of guiding electric wire, be arranged on upper and lower two sides, do not need to identify the upper and lower of bobbin 1, also there is the effect that the location while being placed on reel winder by bobbin 1 becomes and simplifies.
In addition, in the present embodiment, as mentioned above, at the upper and lower surface of bobbin 1, respectively there is 2 pawls and arm, bobbin 12 masks have coincide local.Thereby, even just in case, a side arm or pawl breakage, coincideing of the opposing party's pawl or arm also can stay, and therefore can maintain and prevent the function broken away from from stator core 13.There is the effect that can guarantee reliability.
As shown in the cutaway view of Fig. 6, outer rotation type motor of the present invention comprises: matrix 16; Be fixed on the main shaft 17 on matrix 16 and be fixed on the stator core 13 on matrix 16; And there is permanent magnet 19 and rotate the rotor core 18 be supported on freely on main shaft 17 in the mode relative with stator core 13.
The bobbin 1 that is provided with coil 12 is arranged on stator core 13, and overlap joint line 15 is arranged on the internal side diameter of stator core 13.Thus, the thickness of the coil 12 exposed from stator core 13 because of the structure of concentrate reeling is little, therefore has motor can be configured to slim effect.
In addition, in the present embodiment, do not need bobbin 1 is fixed on the bolt etc. of stator core 13, therefore also there is the effect of the slimming of not destroying.
Fig. 7 means the enlarged drawing of insulating element of the outer transition of embodiments of the invention 2.In the embodiment 1 of Fig. 7 (a), upper and lower surface at bobbin 1 has pawl 2 and arm 4, by coincideing of pawl 2 and arm 4, prevent from the disengaging of stator core 13, but in the embodiment 2 of Fig. 7 (b), replace coincideing of pawl 2 and arm 4, by coincideing of recess 22 and protuberance 24, can prevent from reliably breaking away from from stator core 13.
Utilizability on industry is as follows.
The present invention can be whole for the outer rotation type motor that coil is arranged on to the concentrated coiling on insulating element.In addition, the thickness of its coil of this motor is little, thereby is applicable to slimming, therefore also is well suited for the motor of using as the elevator of elevator.
