As shown in Figure 1, being configured with the busbar retainer 40 of resin in the axial upside (side) of stator 10.And
And busbar retainer 40 keeps multiple busbars 41.The conducting wire (not shown) for constituting coil 11 is drawn from coil 11
It is electrically connected out with busbar 41.For example, in the case where the motor of three-phase synchronous type, pulled out from multiple coils 11 with it is each
Phase or the corresponding conducting wire of neutral point or the conducting wire of both sides are connect with each busbar 41.
Fig. 2 is the top view for schematically showing the structure of busbar retainer 40 of present embodiment.
As shown in Fig. 2, the busbar retainer 40 of present embodiment is made of cricoid plate.Moreover, being protected in busbar
The front for holding frame 40 is provided with multiple groove portions 42a, 42b of storage busbar 41.In the present embodiment, three groove portion 42a etc.
It is positioned apart from radially inner side, three groove portion 42b are equally spaced in radial outside.In addition, these groove portions 42a, 42b
There is no particular limitation for shape, number and configuration, as long as the decision appropriate according to shape of busbar 41 etc..
In addition, being provided with rib 43a, 43b of fixing bus-bars 41 on the side wall of each groove portion 42a, 42b.In addition, at this
In embodiment, shows and the example of two ribs 43a, 43b are set in each groove portion 42a, 42b, as long as however, not limited to this, rib
Shape, number and configuration according to shape of busbar 41 etc. suitably determine.In addition, in order to by busbar 41 steadily
It is fixed, more than two ribs is preferably set.
Fig. 3 A and Fig. 3 B are the solid for schematically showing busbar 41a, 41b for being accommodated in groove portion 42a, 42b respectively
Figure.In addition, there is no particular limitation for the shape of busbar 41a, 41b.
Fig. 4 A is the cross-sectional view of the IV-IV line along Fig. 2.
As shown in Figure 4 A, the rib 43 of present embodiment is arranged to be axially away from and be arranged on busbar retainer 40
Groove portion 42 bottom 40A.That is, the bottom 43A of axial downside and the bottom 40A of groove portion 42 of rib 43 are separated out certain interval.
Fig. 4 B is the sectional view for showing the state for the midway that busbar 41 is pressed into groove portion 42.In addition, Fig. 4 C is to show to make
Busbar 41 is accommodated in the cross-sectional view of the state of groove portion 42.
As shown in Figure 4 B, when busbar 41 is pressed into groove portion 42, rib 43 is by the pressure from busbar 41.However,
Due to there are space, when rib 43 is by pressure from busbar 41, being easy to indentation side on the downside of the axial direction of rib 43
It deforms to (axial downside).Since rib 43 easily deforms, it is thus possible to when busbar 41 is pressed into groove portion 42, suppression
The abrasion of rib 43 processed.As a result, being able to suppress the generation of dirt.In addition, being able to maintain that since rib 43 will not be worn
The retentivity of busbar 41.
On the other hand, since existing rib is formed to the bottom of groove portion, space is not present on the downside of the axial direction of rib.Cause
This, when by pressure from busbar, the deformation to pressing direction of rib is suppressed.As a result, by busbar pressure
When entering groove portion, rib is worn and generates dirt.In addition, when rib is worn, the pressure reduction from rib that busbar is subject to, because
The retentivity of this busbar reduces.On the other hand, increasing the intrusion of busbar to maintain retentivity to make to remittance
Item is flowed when the load becomes large, and storage busbar becomes difficult.As a result, busbar cannot reach the bottom of groove portion sometimes.
In view of this, the rib 43 of present embodiment is when by pressure from busbar 41, due to being easy to indentation side
To deforming, therefore it is able to suppress the abrasion of rib 43.Further, since the contact area of rib 43 and busbar 41 can be made to become
It is small, therefore it is able to maintain that reducing intrusion the load to busbar 41.As a result, rib 43 can be further suppressed
Abrasion.In addition, can be easy to store busbar 41 to the bottom 40A of groove portion 42.
In the present embodiment, there is no particular limitation for the shape of rib 43, but as shown in Figure 4 A, preferably with towards axially
Side and the shape for making the distance between the side wall of opposite side of rib 43 and rib 43 become larger.Such as triangle is enumerated as preferred
Shape.The rib 43 of such a shape is when being pressed into groove portion 42 for busbar 41, it is easier to deform to pressing direction.Separately
Outside, rib 43 and the contact area of busbar 41 can be made smaller.By making the contact area of rib 43 and busbar 41 become smaller,
The abrasion of rib 43 can further be inhibited.
In the above-described embodiment, as shown in Figure 4 A, the upside of the side wall of groove portion 42 is arranged in rib 43 by (variation)
End, but rib 43 is arranged in the position on the side wall of groove portion 42 there is no particular limitation.As long as example, as shown in figure 5, in rib
There are certain spaces for the downside of 43 bottom 43A, then also can be set in the midway of the side wall of groove portion 42.
In addition, in the above-described embodiment, as shown in Figure 4 A, instantiating the rib 43 that axial cross sectional shape is triangle
As the shape of rib 43, but as shown in fig. 6, it is also possible to the rib 43 that axial cross sectional shape is rectangle.In this case, excellent
It is selected as that the corner for the upside for being located at rib 43 is at least provided with corner portion.By being provided with down in the corner for the upside for being located at rib 43
Corner can inhibit the abrasion in the corner of rib 43 when busbar 41 is pressed into groove portion 42.Alternatively, it is also possible to be located at rib 43
The corner of downside is provided with corner portion.
In addition, in the above-described embodiment, as shown in Figure 4 B, instantiating the busbar that axial cross sectional shape is rectangle
41, but as shown in fig. 7, the corner of 43 side of at least rib in the corner of bottom side for being located at groove portion 42 can also be provided with chamfering
Portion.The corner of 43 side of rib in busbar 41 is provided with corner portion, can inhibit when busbar 41 is pressed into groove portion 42
The abrasion of rib 43 caused by being clashed because of 41 corner of busbar and rib 43.Alternatively, it is also possible in the opposite side of 43 side of rib
Corner is provided with corner portion.The corner of opposite side in 43 side of rib of busbar 41 is provided with corner portion, it can be swimmingly
Indentation of the busbar 41 to groove portion 42 is carried out, to improve workability.
In addition, in the present embodiment, there is no particular limitation for the shape when vertical view of the slave end on observation of rib 43, but excellent
It is selected as narrowing towards 41 side width of busbar (circumferential width).Width when vertical view by making rib 43 is towards 41 side of busbar
And narrow, the contact area of rib 43 Yu busbar 41 can be further decreased, therefore can further inhibit the abrasion of rib 43.
For example, triangle shown in Fig. 8 or the trapezoidal preferred shape as rib 43 shown in Fig. 9.
More than, the utility model is illustrated by preferred embodiment, but these are described and non-limiting item,
Certainly various changes are able to carry out.For example, in the above-described embodiment, being provided with groove portion in front as shown in Fig. 2, instantiating
The busbar retainer 40 of 42a, 42b, but the conduction for pulling out from coil can also be for example set on busbar retainer 40
The insertion hole of line insertion and the binding post etc. being electrically connected with external power supply.
In addition, in the above-described embodiment, as shown in Figure 1, instantiating the motor of inner-rotor type, but the horse of outer-rotor type
Up to can also be suitable for the utility model certainly.
