Embodiment
In order to describe structure of the present utility model and characteristics place in detail, lift two following preferred embodiments now and cooperate graphic explanation as after, wherein:
As shown in Figure 1, the Hall element fixed mount 10 of a kind of motor that the utility model first preferred embodiment is provided, be arranged on stacking each other a plurality of silicon steel sheets 41 of a motor, respectively this silicon steel sheet 41 has toward a plurality of extensions 42 of interior radially definite length extended and annular arrangement, the end of these extensions 42 has the alar part 44 that extends to both sides, and the preset distance of being separated by between the alar part 44 of the alar part 44 of an extension 42 and adjacent another extension 42.
This Hall element fixed mount 10 mainly is made up of a pedestal 11, a stator 21 and multiple Hall element 31, wherein:
This pedestal 11, in the form of a ring, the bottom has a plurality of fixing feet 12, these fixing feet 12 be separated by predetermined space and annular arrangement, these pedestal 11 tops have a plurality of fixed parts 14, are three fixed parts 14 in the present embodiment, these fixed part 14 apart preset distances, and annular arrangement is in these pedestal 11 tops.The section of these fixing feet 12 generally is the T font, and have narrow end 121 and thicker end 122, narrow end 121 is embedded at the space between the alar part 44 of adjacent extension 42, and 122 of thicker end are positioned at the outside of these alar parts 44 and are butted on alar part 44, are fixed on these silicon steel sheets 41 by this.
This stator 21 in the form of a ring, is located on this pedestal 11 in the present embodiment, and being subjected to these fixed parts 14 fixes, wherein, this stator 21 has three location divisions, 22 clips in these fixed parts 14, and this stator 21 is promptly fixed with respect to these pedestal 11 clips by this clip relation.These location divisions 22 are the groove for being inwardly concaved by outer rim in present embodiment, and corresponding to the position of these fixed parts 14, under the clip relation, the system of body portion of these fixed parts 14 is embedded in these location divisions 22.
These Hall elements 31 are located at the below of this stator 21, and are passed down through the hollow out zone of these pedestal 11 central authorities.
Fixed mount 10 of the present utility model, the fixing feet 12 that sees through this pedestal 11 are fixed between the alar part 44 of silicon steel sheet 41 of motor, and this kind fixed form can guarantee that this pedestal 11 can be with respect to these silicon steel sheet 41 rotations.In addition, location division 22 clips that pass through this stator 21 can make that in these button portions this stator 21 can be with respect to these pedestal 11 rotations again.By above-mentioned dual clip relation, can make these Hall elements 31 same can be with respect to these silicon steel sheet 41 rotations.Hence one can see that, as long as configure the position of Hall element 31 on this stator 21, these Hall elements 31 can just can directly be located when assembling, do not need to have adjusted the position of Hall element 31 again.
Please consult Fig. 5 to Fig. 6 again, the Hall element fixed mount 50 of a kind of motor that the utility model second preferred embodiment is provided is taken off first embodiment before mainly generally being same as, and difference is:
This pedestal 51 itself is arcuation and has a hollow out position 56 in middle section position, and this stator 61 also is arcuation, and which is provided with a plurality of arcuate sockets 66.
These Hall elements 71 are located at these stator 61 belows and are positioned at this hollow out position 56.
These fixed parts 54 on this pedestal 51 are screw, and these arcuate sockets 66 of this stator 61 are passed for screw in these location divisions 62, and not and these fixed parts 54 be spirally connected fixing.
Among this second embodiment, these pedestal 51 same a plurality of fixing feet 52 of utilizing its bottom fix in silicon steel sheet 41.And remaining structure and assembling mode are taken off first embodiment before all generally being same as, and hold no longer to give and give unnecessary details.
This second embodiment can be by the relation of these arcuate sockets 66 with these location divisions 62, make that this stator 61 can be with respect to the angular movement of this pedestal 51 according to these arcuate sockets 66, to adjust the angle of these Hall elements 71, after adjusting, can be fixed in these fixed parts 54 by these location divisions 62, with the position of these Hall elements 71 of fixed bit.And because pedestal 51 of the present utility model is to be fixed on the silicon steel sheet 41, the situation that tolerance is bigger in the time of therefore can not taking place to be fixed on the end cap as the person of commonly using takes place, and the position of Hall element 71 can maintain position accurately.
As from the foregoing, the attainable effect of the utility model is:
But an ease of assembly: during the utility model assembling, Hall element 31 is direct location, need not rotate the position that pedestal 11 or stator 21 are adjusted Hall element 31.
Two, can not get loose after the assembling: be fixed in silicon steel sheet 41 and pass through location division 22 clips in the fixed part 14 of pedestal 11 by these pedestal 11 bottom fixing feet 12, can make that each member after the assembling does not have the problem that gets loose each other by this stator 21.
