20。
In addition, being configured with by the position of axial downside (other side) to busbar (not shown) relative to circuit board 30
The busbar retainer 40 kept, the busbar are connect with the coil line drawn from stator 10.For example, in three-phase synchronous type
Motor in the case where, each busbar is connect with the coil line of coil line corresponding to each phase or neutral point or the two.And
And the busbar terminal 41 that upside (side) in the axial direction extends is provided on the peripheral part of busbar retainer 40.Here,
The peripheral part of busbar retainer 40 is referred to as the position of 20 side of shell radially, and in Fig. 1, busbar terminal 41 is set to remittance
Flow the upper surface of 20 side of shell of a retainer 40.
Fig. 2 is the bottom view of the bearing retainer 50 from axial downside (other side).In addition, showing electricity with imaginary line
Road plate 30 and busbar retainer 40.
It is protected as shown in Fig. 2, a plurality of leads 90 connecting with circuit board 30 is passed around in circuit board 30 and bearing as shown in Figure 1
It holds in the gap 80 between frame 50, and is exported to the outside of shell 20.Here, a plurality of leads 90 and the periphery for being installed on shell 20
The terminal board 91 in portion connects.In addition, the busbar terminal 41 axially extended from the peripheral part of busbar retainer 40 also with set
The terminal board 42 for being placed in the peripheral part of shell 20 connects.Here, it exemplifies three corresponding to each phase of the motor of three-phase synchronous type
A busbar terminal 41.
In addition, as depicted in figs. 1 and 2, the wall axially extended towards circuit board 30 is provided on bearing retainer 50
Portion 51.Moreover, being leaned on as shown in Fig. 2, being at least around at wall portion 51 from a plurality of leads 90 that circuit board 30 is drawn than wall portion 51
The position of radially inner side, and exported to the outside of shell 20.
In the present embodiment, although as shown in Figure 1, busbar terminal 41 be located at circuit board 30 and bearing retainer 50 it
Between gap 80 in, but by the radially inner side providing walls 51 in busbar terminal 41, and pass around a plurality of leads 90 in wall
The radially inner side in portion 51, therefore can prevent a plurality of leads 90 from interfering with busbar terminal 41.In other words, in circuit board 30
In gap 80 between bearing retainer 50, even if lead 90 partly overlaps radially with busbar terminal 41, by
The radially inner side providing walls 51 of busbar terminal 41, can prevent lead 90 from interfering with busbar terminal 41.In addition, by
It is surrounded in a plurality of leads 90 by wall portion 51, circuit board 30 and bearing retainer 50, therefore at least will not be to the radial direction of wall portion 51
Outside is pierced by.
In the present embodiment, as shown in Figure 1, can have gap between wall portion 51 and circuit board 30, but gap away from
From preferably smaller than the diameter of lead 90.By keeping the distance in gap smaller than the diameter of lead 90, lead 90 can be prevented from wall
Gap between portion 51 and circuit board 30 is pierced by radial outside, therefore can be more reliably prevented from lead 90 and busbar terminal
41 interfere.Alternatively, it is also possible to connect the axial end portion of wall portion 51 with circuit board 30.By the axial end portion for making wall portion 51
It is connect with circuit board 30, and so that the gap between wall portion 51 and circuit board 30 is disappeared, therefore lead 90 can be more reliably prevented from
It is interfered with busbar terminal 41.In the connection of wall portion 51 and circuit board 30, such as it can be attached by bolt etc..
In addition, in the present embodiment, wall portion 51 is preferably Chong Die with circuit board 30 in the axial direction.By make wall portion 51 with
Circuit board 30 is overlapped in the axial direction, can at least be protected in the radially inner side of wall portion 51 using wall portion 51, circuit board 30 and bearing
It holds frame 50 to surround lead 90, therefore lead 90 can be more reliably prevented from and interfered with busbar terminal 41.
In addition, in the present embodiment, as shown in Figure 1, bearing retainer 50 has the holding kept to bearing 70
Portion 52.The maintaining part 52 axially extends in the same manner as wall portion 51 towards circuit board 30, therefore plays function as the second wall portion
Energy.By make maintaining part 52 as second wall portion and function, make a plurality of leads 90 pass around wall portion 51 and maintaining part 52 it
Between, it is interfered so as to be more reliably prevented from lead 90 with busbar terminal 41.
Fig. 3 is the partial sectional view for schematically showing the structure of the motor of other embodiments of the utility model.
Here, the structure other than bearing retainer 50 is identical as structure shown in FIG. 1.
As shown in figure 3, in the present embodiment, being configured relative to circuit board 30 by the position of axial upside (side)
There is plate 60.Here, plate 60 is configured to partly overlap with circuit board 30 in the axial direction.
In the present embodiment, as shown in Figure 1, being arranged on plate 60 instead of the providing walls 51 on bearing retainer 50
The first wall portion 61 and the second wall portion 62 axially extended towards circuit board 30.Here, the first wall portion 61 and the second wall portion 62 are matched
It is set to and partly overlaps radially.
In the present embodiment, it passes around from a plurality of leads 90 that circuit board 30 is drawn in the first wall portion 61 and the second wall portion 62
Between, and exported to the outside of shell 20.By passing around a plurality of leads 90 between the first wall portion 61 and the second wall portion 62, energy
It surrounds lead 90 by the first wall portion 61, the second wall portion 62, circuit board 30 and plate 60, therefore lead 90 can be prevented and converged
Stream terminal 41 interferes.
In addition, in the present embodiment, there are two wall portions 61,62 for setting on plate 60, but wall portion is also possible to one certainly.
In this case, lead 90 is around the position that radially inner side is leaned on than wall portion.
In the present embodiment, as long as wall portion is located at the position Chong Die with circuit board 30 in the axial direction.Therefore, more
Bar lead 90 is around the gap between circuit board 30 and busbar retainer 40 and in situation derived from the outside of shell 20,
The wall portion axially extended towards circuit board 30 can also be set on busbar retainer 40.
In addition, in the present embodiment, interfering object as with a plurality of leads 90 drawn from circuit board 30, illustrate
Busbar terminal 41 and be illustrated, but other than busbar terminal 41, for configuring the electrical connection section in motor
Same effect can be also played with conducting wires such as coil lines.That is, in the gap (such as circuit board 30 and the bearing that are passed around for lead 90
Gap 80 between retainer 50) in, in the case that lead 90 and electrical connection section etc. partly overlap radially, pass through setting
The wall portion of present embodiment can prevent lead 90 and electrical connection section etc. from interfering.
More than, the utility model is illustrated by embodiment appropriate, but these are described and non-limiting item,
Certainly various changes are able to carry out.For example, in the above-described embodiment, as shown in Figure 1, the motor of inner-rotor type is instantiated,
But the motor of outer-rotor type can also be suitable for the utility model certainly.
