Description

Compact stator core
Technical field
The utility model relates to technical field of motors, in particular, relates to compact stator core.
Background technology
Motor is widely used in the various electric equipments of industrial production and life, and existing plastic packaging motor has stator and rotor, and stator has stator core and is wrapped in the coil on stator core, and the outer injection moulding of stator forms plastic packaging shell.Rotor is cage rotor, and it has rotor core, and has cast-in aluminum squirrel cage in rotor core top casting.The middle part of rotor is provided with armature spindle, armature spindle usually with rotor interference fit, and to rotate with the rotation of rotor, and armature spindle is for outside outputting power.
In order to reduce over flow area, reduce iron core heating, iron core stator is laminated by multilayer silicon steel sheet usually, and this is that induced field forms induced electromotive force in the core which due to insulated from each other between multilayer silicon steel sheet, produces induced current and reduces eddy current loss and magnetic hysteresis loss.
In prior art, at least there are the following problems: the lamination assembled structure of stator core coordinates not tight, easy leakage field.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Overlay to arrange well compact compact stator core.
For achieving the above object, the utility model provides following technical scheme: a kind of compact stator core, the evenly spaced multiple stator tooth of circumference comprising circular yoke portion and extend along direction, the center of circle from described yoke portion, described two often adjacent stator tooths form a stator slot, and described stator tooth is mutually around making to be formed centrally circular hole in a hollow in stator punching, this stator core is divided into uniformly according to the number of described stator tooth and identical with stator tooth quantity patches block, the described block that patches laminates shaping by multi-disc stator punching, one end that described stator punching is positioned at yoke portion is provided with protuberance, in addition while be provided with the recess matched with this protuberance, a locating recesses is provided with in the surface of the stator tooth of stator punching, be provided with in the surface in the yoke portion of stator punching with centrosymmetric other two locating recesses of this locating recesses.
The utility model is set to further: the shape of described protuberance and recess is semicircle or rectangle or trapezoidal or triangle etc.
The utility model is set to further: described stator tooth comprises tooth root and tooth top, and in " T " font, is formed with fillet R between this tooth root and yoke portion.
The utility model is set to further: the quantity of described stator tooth is 9.
Compared with prior art, the utility model has the advantage of: by being arranged on the locating recesses on stator punching, making to laminate the shaping block that patches by stator punching arranges more regular, again by the stator core patching block and form, overall tightness is higher, overcomes existing motor stator core internal structure and coordinates not tight, the problem of easy leakage field, and then decrease mating surface leakage field, reach the effect improving electric efficiency.And the stator tooth of " T " font, its tooth root and yoke portion are formed with fillet R, ensure that the bonding strength in itself and yoke portion, prevent the generation that local stress is excessive.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the stator punching of the utility model compact stator core embodiment;
Fig. 2 is the schematic diagram patching block of the utility model compact stator core embodiment;
Fig. 3 is the overall schematic of the utility model compact stator core embodiment.
In figure, 1, yoke portion; 2, stator tooth; 31, protuberance; 32, recess; 4, locating recesses; 5, fillet R; 6, interior circular hole; 7, stator slot; E, stator punching; F, patch block; G, stator core.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model stator core embodiment is described further.
The evenly spaced multiple stator tooth 2 of circumference that the present embodiment comprises circular yoke portion 1 and extends along direction, the center of circle from described yoke portion 1, described stator tooth 2 comprises tooth root and tooth top, and in " T " font, fillet R5 is formed between this tooth root and yoke portion 1, the quantity of described stator tooth 2 is 9, described two often adjacent stator tooths 2 form a stator slot 7, and described stator tooth 2 is mutually around making to be formed centrally circular hole 6 in a hollow in stator punching E, this stator core G is divided into uniformly according to the number of described stator tooth 2 and identical with stator tooth 2 quantity patches block F, the described block F that patches laminates shaping by multi-disc stator punching E, one end that described stator punching E is positioned at yoke portion 1 is provided with protuberance 31, in addition while be provided with the recess 32 matched with this protuberance 31, the shape of described protuberance 31 and recess 32 is semicircle or rectangle or trapezoidal or triangle etc., a locating recesses 4 is provided with in the surface of the stator tooth 2 of stator punching E, be provided with in the surface in the yoke portion 1 of stator punching E with centrosymmetric other two locating recesses 4 of this locating recesses 4.
According to said structure and accompanying drawing, by being arranged on the locating recesses 4 in stator tooth 2 and yoke portion 1, these locating recesses 4 form a leg-of-mutton shape, laminated by these stator punchings E and shaping patch block F and will arrange ordering rule more, preferably elect the shape of protuberance 31 and recess 32 as semicircle, firmly convenient at plug-in type, the stator core G that block F forms is patched by these, can while when splicing patches block F, while formed stator slot 7 in coiling, thus improve coiling copper factor, ensure that motor performance optimization; Again by the stator core G patching block F and form, overall tightness is higher, overcomes existing motor stator core G internal structure and coordinates tight, the problem of easy leakage field, and then decrease mating surface leakage field, reach the effect improving electric efficiency.And the stator tooth 2 of " T " font, its tooth root and yoke portion 1 are formed with fillet R5, ensure that the bonding strength in itself and yoke portion 1, prevent the generation that local stress is excessive.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
