In addition, on circuit substrate 16,4 terminals 64 of the distribution position of the regulation of printed wiring 52 and conducting are formed on the peripheral position of periphery of coil 25.And these terminals 64 make the outer circumferential side wire ends 66 of coil 25 be electrically connected with interior all side line materials end 68 by scolding tin.In addition, two terminals 64 that are connected with all side line materials end 68 in each are electrically connected with the terminal connecting portion 70 that forms with scolding tin or welding.In addition, two terminals 64 that are connected with each outer circumferential side wire ends 66 are connected with the power sourced electric of electric equipment etc., thus, and by of the both sides power supply of these terminals 64 to coil 25.
In addition, stretch out from the inner peripheral surface 25a of coil interior all side line materials end 68 of coil 25, and all side line materials end 68 must be connected with the terminal 64 that is positioned at coil 25 foreign sides in this.Therefore, interior all side line materials end 68 of coil 25 is by being formed at the gap of above-mentioned base material exposed division 62, by from side directed outer terminal 64 to coil 25 of the interior week of coil 25.Below, the state of the interior all side line materials end 68 on base material exposed division 62 is explained with reference to Fig. 9.
As shown in Figure 9, coil 25 and circuit substrate 16 cohere by adhesive 72.In addition, be clipped in the adhesive 72 between coil 25 and the circuit substrate 16, also filling is in the gap of base material exposed division 62.And diameter is interior all side line materials end 68 of about 0.07mm, along filling the base material 50 in the base material exposed division 62 of adhesive 72, extend to the outside of coil 25 from interior all sides of coil 25.Like this, interior all side line materials end 68, owing to utilizing the adhesive 72 that coil 25 and circuit substrate 16 are cohered to fix, thus can be fixed on reliably coil 25 below.
In addition, the diameter of the wire rod of coil 25, promptly in the diameter of all side line materials end 68, for example be about 0.07mm, roughly the same with the height in the gap of base material exposed division 62.Therefore, carry the coil 25 on circuit substrate 16, come-up ground is not configured to almost parallel with circuit substrate 16 on base material exposed division 62.Like this, by base material exposed division 62, because interior all side line materials end 68 of coil 25 is drawn to the outside of coil 25,, can be reasonably interior all side line materials end 68 of coil 25 be connected with terminal 64 so can prevent the come-up of coil 25 parts.Therefore, owing to can eliminate the inclination of the coil 25 that the accident come-up of following coil 25 causes,, help making the clearance portion of magnet 31 and coil 25 to become and like that brushless motor 10 is made slimming less than 0.5mm so can make coil 25 and magnet 31 approaching.
In addition, the diameter of interior all side line materials end 68 and the height of base material exposed division 62 not necessarily will make same degree, as long as it is just passable to form base material exposed division 62 slightly.In such occasion, also can suppress the come-up of coil 25.In addition, comprise the gauge or diameter of wire of the coil 25 of the outer circumferential side wire ends 66 of coil 25 and interior all side line materials end 68, if greater than 0.01mm to just can less than the scope of 0.1mm.That is to say, diameter is less than the wire rod of 0.01mm, have any problem aspect the small-sized brushless motor making.In addition, diameter is being used for the occasion of brushless motor 10 greater than the wire rod of 0.1mm, the coil that is formed by this wire rod just maximizes.Corresponding therewith, brushless motor 10 just maximizes, and is being unfavorable aspect the miniaturization that promotes brushless motor 10.
Then, to adopting and the brushless motor 10 of above explanation situation, describe with reference to Figure 10 with the fan motor of spline structure.In addition, the key element identical or equal with brushless motor 10 put on identical symbol, and the repetitive description thereof will be omitted.
As shown in figure 10, in fan motor 80, the structure of basket 82 is different with the structure of the basket 19 of brushless motor 10.That is to say, the basket 82 of fan motor 80, by in the above with below or side have peristome rectangular shape substructure member 84 and the foursquare lid 86 that the open sides of substructure member 84 closes lid constituted.
In addition, fan motor 80 is fixed on the rotor 30 by a plurality of (for example 5) blade 88 and replaces weight 33 and to produce vibration different with brushless motor 10.This blade 88, on being fixed in rotor 30 or axle 20 in, and outstanding at radial direction from rotor 30 or axle 20 outer peripheral edges.In addition, each blade 88 rotates integratedly with rotor 30.
In addition, on lid 86, on the position corresponding, be formed with air entrance hole 86a with blade 88.Therefore, when blade 88 and rotor 30 became one and rotate, 86a imported air forcibly in fan motor 80 by this air entrance hole.In addition, below substructure member 84, on the position corresponding, be formed with air tap 84a with the outstanding part of blade 88.And, when blade 88 and rotor 30 rotate with becoming one, by this air tap 84a air-out forcibly in the fan motor 80.
In addition, in this fan motor 80, on circuit substrate 16, be formed with base material exposed division 62 (with reference to Fig. 9).Therefore, because interior all side line materials end 68 of coil 25 is derived to the outside of coil 25, coil 25 self can not make interior all side line materials end 68 of coil 25 be connected with terminal 64 in 68 places, interior all side line materials end come-up.Do like this, can promote the slimming of fan motor 80.
