Herein, as shown in Figure 5, under the state that drive coil 4 is supported in stator core 30, salient pole 32 to comprise from the cylinder portion 36 of bobbin 33 towards radially inner side outstanding projection 32a, and stator core 30 is by embedding pod 64 from below by this projection 32a under being supported in the state being positioned partition 18.That is, pod 64 can be chimeric with the projection 32a of salient pole 32, by embedding projection 32a in chimeric mode, stator 5 is positioned partition 18 around central axis L.In addition, by making projection 32a abut with the inner peripheral surface part 64a of the upper end of pod 64, stator 5 is positioned partition 18 on central axis L direction.Under the state that stator 5 is positioned partition 18, be located at the terminal pins fixing part 38 of lower flange 37 overlapping with inner peripheral surface part 64a on central axis L direction, the two end portions of the circumference of its upper-end surface 38b is in the state abutted with the lower end surface part 65a of protuberance 65 (with reference to Fig. 3), wherein, the lip part 37 being positioned at radially inner side of three drive coils (1) ~ 4 (3) of the position overlapping with connector 9 is configured in when above-mentioned lip part 37 refers to and observes from central axis L direction.In addition, be configured in and be in the lip part 37 being positioned at radially inner side of nine drive coils 4 (4) ~ 4 (12) of the nonoverlapping position of connector 9 state abutted with the outer circumferential face part of the arc-shaped of lip part 65.
Resin seal member 19 is for the protection of drive coil 4 and circuit substrate 7 in order to avoid they are subject to the impact of fluid, and it is made up of resins such as unsaturated polyester resins.Resin seal member 19 be by by resin injection to be in be fixed with stator 5 and circuit substrate 7 state under partition 18 and formed.In addition, drive coil 4 and circuit substrate 7 cover by resin seal member 19 completely, and by except in connector 9 from circuit substrate 7 towards connector connection part 9a protruding outside except connector 9 a part cover.
When carrying out molding and forming to resin seal member 19, connector 9 is fixed on circuit substrate 7, and circuit substrate 7 and stator 5 are fixed on partition 18.Then, under the state utilizing mould (not shown) to keep the outer peripheral edge portion 22a (with reference to Fig. 5) of partition lip part 22 and the connector connection part 9a of connector 9, stator 5 and circuit substrate 7 are configured in mould.Then, resin seal member 19 is formed by resin is injected mould from the cast gate being located at mould and makes it solidify.
Herein, cast gate is located at than circuit substrate 7 more by radial outside and than the position of connector 9 closer to fastener hole 50.In addition, the outer circumferential side of drive coil 4 is located at by cast gate.Consequently, as shown in Figure 1, shown in Figure 5, in resin seal member 19, be positioned at the outer circumferential side of drive coil 4 and be formed with gate vestiges 70 than connector 9 closer to the position of fastener hole 50.In this example, the center of gate vestiges 70, fastener hole 50, central axis L, drive integrated circult 40 and connector 9 are positioned on straight line.
(action effect)
According to this example, the retention mechanism 49 for circuit substrate 7 being fixed on partition 18 is located at towards the position of radial outside away from central axis L.Therefore, situation about being located on central axis L with retention mechanism 49 compares, and can guarantee large space on circuit substrate 7.Therefore, easily the drive integrated circult 40 as larger components and parts is configured at circuit substrate 7.In addition, when forming the wiring pattern 43 of drive circuit 6 on circuit substrate 7, the design freedom of wiring pattern 43 can be improved.
In addition, according to this example, retention mechanism 49 is located at and is positioned at the position with connector 9 opposite side across central axis L, therefore, can guarantee large space, and can suppress the loss of electric power in the part near connector 9.
In addition, according to this example, connector 9 comprises the bonder terminal 55 extended abreast with circuit substrate 7, and this bonder terminal 55 is soldered on connector connecting pad 43c.Therefore, the attachment portion between bonder terminal 55 and connector connecting pad 43c is elongated, can improve the adhesive strength of soldering.In addition, connector 9 by the fixing hook portion 56 of being located at connector 9 be located at substrate connector fixed hole 53 engaging and be installed on circuit substrate 7.Therefore, fixedly become firm between connector 9 and circuit substrate 7, even if the connector connection part 9a that mould will utilized time shaping for resin seal member 19 to keep connector 9, connector 9 also can not depart from from circuit substrate 7.
Then, in this example, use mould when carrying out shaping to resin seal member 19, resin is more injected than the side of connector 9 closer to retention mechanism 49 by radial outside by from than circuit substrate 7.In addition, when observing from central axis L direction, the center of cast gate (gate vestiges 70), fastener hole 50, central axis L and connector 9 are positioned on straight line.Therefore, the resin because injecting can be suppressed and make the situation that circuit substrate 7 bends.In addition, resin is more injected by the side of drive coil 4 than circuit substrate 7 by from central axis L direction, and the wiring pattern 43 of drive circuit 6 is located at the real estate 7a with the downside of multiple drive coil 4 (1) ~ 4 (12) opposite side in circuit substrate 7.Therefore, when using mould to carry out shaping to resin seal member 19, can prevent or suppress the wiring pattern 43 making because of injected resin to be located at circuit substrate 7 to peel off.
In addition, the long side direction of drive integrated circult 40 is orthogonal with the imaginary line L1 center of cast gate (gate vestiges 70), fastener hole 50, central axis L and connector 9 connected, therefore, when carrying out shaping to resin seal member 19, the length of drive integrated circult 40 on the direction that circuit substrate 7 bends is shorter.Consequently, can prevent drive integrated circult 40 from peeling off or damage from substrate.
In addition, the end portion of the winding wire 34 of each drive coil 4 is wound in terminal pins 35 in a relaxed state, therefore, when carrying out shaping to resin seal member 19, can prevent or suppress the end portion of the cutting line astragal 34 because of injected resin.
