Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
The utility model provides a kind of stator for brshless DC motor, specifically, as shown in Figure 1 to Figure 3, stator bag
Include：Stator core 1；Insulation framework 2, the injection molding of insulation framework 2 surround stator core 1 on stator core 1 and including multiple
The uniform winding skeleton unit 3 of central axis, the peripheral part of winding skeleton unit 3 sets fluted 4, shape in insulation framework 2
Into the installation through-hole for having multiple central axis parallel to stator core 1；Stator winding, stator winding is by by more enamel-covered wires
Formed on each winding skeleton unit 3；And multiple lead pin 5, it is logical that each lead pin 5 is separately positioned on installation
Electrically connected in hole and correspondingly with the end of a thread or line tail of enamel-covered wire, wherein, enamel-covered wire includes being located at each winding skeleton
Across guiding principle line between unit 3 and between winding skeleton unit 3 and lead pin 5, across guiding principle line are partly spacing in groove 4
In.
Stator of the present utility model for brshless DC motor is recessed due to being provided with the peripheral part of winding skeleton unit 3
Groove 4, and will across guiding principle line it is partly spacing in groove 4, thus solve across guiding principle line it is at random or after hanging easily with stator core 1 or
Lead pin 5 contact and caused by defective insulation and short circuit electric leakage the problem of.
It should be noted that stator core 1, insulation framework 2, winding skeleton unit 3, stator winding and lead pin 5
The specific bearing of trend of concrete shape or particular type and groove 4 can be arranged as required to, and these belong to this reality
Within new range of the technology design.The concrete form of features described above will be illustrated in a manner of specific embodiment below.
Of the present utility model in the stator of brshless DC motor, because each winding skeleton unit 3 is along stator iron
The circumferential direction arranged for interval of core 1, therefore across the guiding principle line between each winding skeleton unit 3 is generally also along stator core
1 circumferential direction arrangement, therefore groove 4 is preferably to extend along the circumferential direction of stator core 1, in order to which above-mentioned across guiding principle line is embedded in
In groove 4.
Further, since across the guiding principle line between winding skeleton unit 3 and lead pin 5 is typically relative tilt ground cloth
Put, therefore groove 4 can extend on the peripheral part of winding skeleton unit 3 along inclined direction, and one end of groove 4 is close
Lead pin 5, the other end is close to winding skeleton unit 3, in order to which above-mentioned across guiding principle line is embedded in groove 4.
Of the present utility model in the stator of brshless DC motor, it is preferable that insulation framework 2 also includes being arranged on phase
Wrapping post 6 between adjacent winding skeleton unit 3, so as to use same root enamel-covered wire when winding skeleton unit 3 adjacent to each other
When winding successively, between adjacent winding skeleton unit 3 can be around the outer peripheral face of wrapping post 6 across the center section of guiding principle line
(i.e. away from stator core 1 central axis face) front, it is above-mentioned across the both ends of guiding principle line respectively from two adjacent winding skeletons
Gap between unit 3 and wrapping post 6 is inwardly wound up on winding skeleton unit 3, thus by adjacent winding skeleton unit 3 it
Between across guiding principle line it is spacing, prevent that across the guiding principle line is at random or contacted after hanging with stator core 1 or lead pin 5 and caused by absolutely
Edge is bad and the problem of short-circuit electric leakage.Specifically, as shown in figure 1, wrapping post 6 is formed as rectangular block and along stator core 1
The bearing of trend extension of central axis, is thus arranged to simple shape, to reduce the injection molding of insulation framework 2 by wrapping post 6
Difficulty.
Above-mentioned in the stator of brshless DC motor, it is highly preferred that the center of the remote stator core 1 of wrapping post 6
Formed with limited impression on the face of axis, so as to which across the guiding principle line between adjacent winding skeleton unit 3 is spacing spacing
In groove, further prevent that across the guiding principle line is at random or contacted after hanging with stator core 1 or lead pin 5 and caused by insulation
The problem of bad and short-circuit electric leakage.
Of the present utility model in the stator of brshless DC motor, specifically, multiple winding skeleton units 3 to include more

In the periphery boss 7 of the first skeleton unit 8, therefore the enamel-covered wire on winding skeleton unit 3 can be with most short circuit
Electrically connected with lead pin 5.
Above-mentioned in the stator of brshless DC motor, due to being provided with periphery boss 7 on the first skeleton unit 8, because
The periphery boss 7 of this first skeleton unit 8 is relative to be protruded, and across guiding principle line is necessarily preferentially resisted against the periphery boss 7 of relative protrusion
On, in order to preferably spacing across guiding principle line, groove 4 is formed on the outer peripheral face of periphery boss 7.
Above-mentioned in the stator of brshless DC motor, further specifically, multiple winding skeleton units 3 also to include more
Individual the second skeleton unit 9 being separately positioned between two the first skeleton units 8, so as to formed a special winding enamel-covered wire and
It is not provided with the second skeleton unit 9 of lead pin 5, therefore the enamel-covered wire on the first skeleton unit 8 of the front side of the second skeleton unit 9
Can the first wrapping post 6 around the front side of the second skeleton unit 9 and then again on the second skeleton unit 9, enamel-covered wire is second
Wound on skeleton unit 9 further around the wrapping post 6 for crossing the rear side of the second skeleton unit 9 after pre- fixing turn, finally again wound on the second bone
On first skeleton unit 8 of the rear side of frame unit 9.
It should be noted that only illustrate a kind of method for winding of enamel-covered wire by way of example above, it should be understood that
It is that enamel-covered wire also has other method for winding, will not be repeated here.
Above-mentioned in the stator of brshless DC motor, further specifically, stator winding to include multiple winding coils,
Winding coil is by the way that enamel-covered wire is formed wound on winding skeleton unit 3, so as to be wound respectively on each winding skeleton unit 3
Enamel-covered wire and form winding coil, ultimately form stator winding.
In addition, the utility model additionally provides a kind of brshless DC motor, brshless DC motor includes rotor and this practicality
The new stator for brshless DC motor.
Brshless DC motor of the present utility model is with the above-mentioned stator for brshless DC motor relative to prior art institute
Have the advantage that identical, will not be repeated here.
Preferred embodiment of the present utility model, still, the utility model and unlimited is described in detail above in association with accompanying drawing
Detail in above-mentioned embodiment, can be to skill of the present utility model in range of the technology design of the present utility model
