Describe according to the motor 100 of the embodiment of the present invention below with reference to Fig. 1 a-Fig. 6.
As shown in Fig. 1 a-Fig. 3 d, according to the motor 100 of the embodiment of the present invention, comprising: rotor 1, stator 2 and support 3.
Stator 2 is located at outside rotor 1, and in other words, rotor 1 is located in stator 2 rotationally.Stator 2 comprises stator core 21 and stator 2 windings, stator 2 windings are wrapped on stator core 21, particularly, on stator core 21, be formed for holding centre bore and multiple stator slot of rotor 1, multiple stator slots are all communicated with centre bore, and stator 2 windings are wrapped on stator core 21 through multiple stator slots.Wherein, stator core 21 can be by stacked the forming of multiple stator punchings 211.
Support 3 is located at the bottom of stator core 21, and support 3 can support stator 2 and rotor 1, and stator 2 and rotor 1 can be fixed on such as household electrical appliance of other parts etc. by support 3.
Wherein, support 3 is one-body molded with stator core 21.Support 3 and the preferred integrated injection molding of stator core 21, now support 3 can be working of plastics.Thus, by by support 3 and stator core 21 one machine-shapings, fixed between support 3 and stator core 21, thus the phenomenon that there will not be stator core 21 to come off from support 3.
According to the motor 100 of the embodiment of the present invention, by by one-body molded to support 3 and stator core 21, improve the bonding strength between stator core 21 and support 3, thereby improved the connection reliability of motor 100, and improve the overall efficiency of assembling of motor 100, thereby saved cost.
According to a specific embodiment of the present invention, as shown in Figure 6, support 3 comprises fixed part 31 and two connecting portions 32, two connecting portions 32 lay respectively at the both sides of fixed part 31, stator 2 and rotor 1 can be arranged on such as household electrical appliance of other parts etc. by two connecting portions 32, wherein, stator core 21 is located on fixed part 31.Support 3 is preferably symmetrical structure.
Alternatively, fixed part 31 is that rectangle is tabular, two connecting portions 32 lay respectively at the relative both sides of fixed part 31, for example, two connecting portions 32 are connected to the left and right sides of fixed part 31, each connecting portion 32 all extends along fore-and-aft direction, and now the bearing of trend of each connecting portion 32 is identical with the bearing of trend of the axis of stator core 21.Certainly, two connecting portions 32 can also be connected to the both sides, front and back (scheming not shown) of fixed part 31.
In order to ensure the intensity of support 3, can suitably increase the thickness of support 3, for example increase the thickness of fixed part 31.In the time that the each several part thickness of support 3 does not wait, there is the situation of distortion in support 3 in uneven thickness for fear of each several part and after injection moulding is completed, can on support 3, offer through hole 311 so that the thickness of support 3 each several parts is substantially equal.
Particularly, on fixed part 31, be formed with at least one through hole 311 of perforation.With reference to Fig. 6 and in conjunction with Fig. 4 and Fig. 5, through hole 311 is the spaced apart distributions of multiple and multiple through holes 311, each through hole 311 all extends along fore-and-aft direction, and the front-end and back-end of each through hole 311 connect respectively front end face and the rear end face of fixed part 31, thereby the thickness of the each several part of support 3 is roughly equal, there will not be injection moulding to complete after-poppet 3 and occur the situation of distortion, and be convenient in demoulding.The number that is appreciated that through hole 311 can be according to actual requirement specific design, and the present invention does not do concrete restriction to this.
One of them in support 3 and stator core 21 is provided with at least one projection 34, is formed with and projection 34 at least one groove coordinating on another in support 3 and stator core 21.That is to say, projection 34 can be located on support 3, also can be located on stator core 21, and similarly, groove can be formed on support 3, also can be formed on stator core 21.It should be noted that, when projection 34 is while being located on support 3, on stator core 21, should be formed with at least one groove to coordinate with projection 34, similarly, in the time that groove is formed on support 3, on stator core 21, should be provided with at least one projection 34 with groove fit.Thus, by groove and projection 34 are set, can further improve the bonding strength between support 3 and stator core 21, thereby further improve the connection reliability of motor 100.
At least one projection 34 is located on the upper surface of support 3, and at least one groove is formed on the bottom of stator core 21.As shown in Figure 5 and Figure 6, two projection 34 spaced apart distributions on the upper surface of support 3, the bottom of stator core 21 is formed with two grooves, and two projections 34 are engaged in respectively in two grooves, and size, the shape of projection 34 and groove are all roughly the same.Wherein, projection 34 and groove are all formed as inverted trapezoidal shape, but are not limited to this.
With reference to Fig. 1 a, Fig. 1 b and Fig. 4-Fig. 6, two ends on the length direction of each connecting portion 32 are formed with respectively a connecting hole 321, when installation, can be with screw respectively through the connecting hole 321 on each connecting portion 32, whole motor 100 is arranged on such as household electrical appliance of other parts etc.
Further, motor 100 further comprises: boss 33, and boss 33 is located on the upper surface of support 3, and alternatively, boss 33 is by protruding upward formation of a part of the upper surface of support 3, so that stator core 21 is supported.Its protrusions 34 is located on boss 33.
As shown in Fig. 3 a-Fig. 3 d, motor 100 also comprises: 4, two end caps 4 of two end caps are located at respectively the axial both sides (for example, the both sides, front and back in Fig. 3 b) of stator 2.When installation, bolt 5 can be from back to front connected with nut 6 after the end cap 4 through the end cap 4 of rear side, stator 2, front side successively, so that two end caps 4 and stator 2 are linked into an integrated entity.Certainly bolt 5 also can be from front to back connected with nut 6 after the end cap 4 through the end cap 4 of front side, stator 2, rear side successively (scheming not shown).The number and the arrangement that are appreciated that bolt 5 can specifically be arranged according to actual requirement, to reach better connection effect.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And specific features, structure, material or the feature of description can be with suitable mode combination in any one or more embodiment or example.
