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.
