(the main effect of present embodiment)

As discussed above, in the present embodiment, first bobbin 31 comprises the first terminal platform 314, this the first terminal platform 314 remains in side's side end on the motor axis L direction with the first terminal pin 11, and second bobbin 32 comprises second terminal board 324, and this second terminal board 324 remains in side's side end on the motor axis L direction towards the leading section of the arm 325 that upwards extends with the first terminal platform 314 position adjacent in week with second terminal pins 12.Therefore, owing on a position of stator 3, winding wire (first winding wire 36 and second winding wire 37) is powered the therefore simplification of energy implementation structure.

In addition, after first winding wire 36 is wound in first bobbin 31, the end of first winding wire 36 is bound in the first terminal pin 11, and after second winding wire 37 is wound in second bobbin 32, the end of second winding wire 37 is bound in second terminal pins 12, after this first bobbin 31 and second bobbin 32 is arranged to get final product on motor axis L direction.Therefore, in the manufacturing process of motor 1, even the side in first bobbin 31 and second bobbin 32 is short-circuited or the situation of fault such as broken string under, also need not stator 3 integral body are abandoned.In addition, because winding wire is wound in first bobbin 31 and second bobbin 32 respectively, therefore can carry out the winding work of winding wire expeditiously.Therefore, can improve the rate of finished products and the productivity of motor.

In addition, the end of second winding wire 37 extends to second terminal pins 12 through the radial outside of arm 325.Therefore, because the drawing around being folded with arm 325 between the part of second terminal pins 12 and first winding wire 36 of second winding wire 37, even therefore take place laxly on second winding wire 37, second winding wire 37 can not be short-circuited with first winding wire 36 yet.

In addition, in the first terminal pin 11 and second terminal pins 12, one square end side of long axis direction is winding wire tie part 11b, 12b, and the opposing party of long axis direction is distolateral to be distribution material connecting portion 11a, 12a, winding wire tie part 11b, 12b and distribution material connecting portion 11a, 12a is divided open.Therefore, come the end of the end of first winding wire 36 and second winding wire 37 is given lax even winding wire tie part 11b, 12b side carried out such processing such as bending, distribution material connecting portion 11a, 12a side can not be shifted yet.Therefore, wiring substrate 8 can be connected in easily and reliably distribution material connecting portion 11a, 12a.

And, in the first terminal pin 11 and second terminal pins 12, because winding wire tie part 11b, 12b are outstanding towards radial outside, therefore can carry out the end of first winding wire 36 and second winding wire 37 is bound in the operation of winding wire tie part 11b, 12b expeditiously.Under the situation of said structure, also after the end with the end of first winding wire 36 and second winding wire 37 is bound in the first terminal pin 11 and second terminal pins 12, only need just can give lax with winding wire tie part 11b, 12b towards cylindric metastomium 310,320 side warpages to the end of first winding wire 36 and the end of second winding wire 37.

And, in the arm 325 of second bobbin 32, constituting guide part, this guide part limits end the drawing around the position when second terminal pins 12 is extended that makes second winding wire 37 by projection 329.In addition, the same with the arm of second bobbin 32 in the arm 315 of first bobbin 31, also constitute guide part, this guide part limits end the drawing around the position when the first terminal pin 11 extends that makes first winding wire 36 by projection 319.Therefore, draw around first winding wire 36 and second winding wire 37, therefore exist to be not easy to take place the such advantage of winding wire short circuit each other owing to can pass assigned position.

And, in the present embodiment, be installed on motor field frame 2 by the connector shell 90 that will keep bonder terminal 95, when constituting connector portion 10, owing on second bobbin 32, be formed with the holding section 323 that engages with connector shell 90, so connector shell 90 can be positioned second bobbin 32 accurately.Consequently, connector shell 90 also is positioned first bobbin 31 accurately.Therefore, distribution material connecting portion 11a, the 12a of the first terminal pin 11 and second terminal pins 12 and the positional precision height of bonder terminal 95.Therefore, can adopt the structure of utilizing wiring substrate 8 that the first terminal pin 11 and second terminal pins 12 are connected with bonder terminal 95.Therefore, the end of the end of first winding wire 36 and second winding wire 37 is bound in the first terminal pin 11 and second terminal pins 12 gets final product, and the end of the end of first winding wire 36 and second winding wire 37 need not to be bound in bonder terminal 95.Therefore, can improve the productivity of motor 1.And, because the first terminal pin 11 and distribution material connecting portion 11a, the 12a of second terminal pins 12 and the positional precision height of bonder terminal 95, therefore under the situation that wiring substrate 8 can't be out of shape for rigid substrate, also can be during wiring substrate 8 in configuration, make side's side end of the distribution material connecting portion 12a of distribution material connecting portion 11a, second terminal pins 12 of the first terminal pin 11 and bonder terminal 95 run through the through hole 81 of wiring substrate 8 reliably.Therefore, can be easily and be welded in the pad 82 of wiring substrate 8 reliably with scolding tin with side's side end of the distribution material connecting portion 12a of the distribution material connecting portion 11a of the first terminal pin 11, second terminal pins 12 and bonder terminal 95.Therefore, owing to can adopt cheap rigid substrate, therefore can reduce the component costs of motor 1 as wiring substrate 8.

At this, for holding section 323, also can form engaging recessed part.Yet, in the present embodiment, because holding section 323 is formed the engaging protuberance of the recess 99 that is embedded in connector shell 90, therefore compare with the situation that holding section 323 is constituted engaging recessed part, can simplify the structure of the mould when making second bobbin 32 by ester moulding.In addition, in second bobbin 32,,, also can simplify the structure of second bobbin 32 even therefore on second bobbin 32, constitute the holding section because the outer circumferential side end of flange part 322 is located in holding section 323.In addition, owing to the flange part 322 that holding section 323 is formed at second bobbin 32,, on second bobbin 32, also be not easy to deform even therefore when aerial lug is combined with connector portion 10, push holding section 323.In addition, be embedded in holding section 323 under the state of recess 99, the leading section of holding section 323 is the state of giving prominence to from recess 99.Therefore, because when aerial lug (not shown) was combined with connector portion 10, the leading section of holding section 323 engaged with aerial lug, so can utilize holding section 323 to carry out the location of aerial lug and prevent to extract etc.
