Description
Technical field
The utility model relates to a kind of process technology of motor, relates in particular to a kind of process technology of plastic packaging monopole asynchronous motor.
Background technology
Traditional stator core adopts the mode of full circle to open material when opening material mostly, promptly directly goes out the stator core of a circle on a silicon steel plate, winds the line then or rule, and this defective of holding the material mode is to produce a lot of waste materials, causes very big waste.
Summary of the invention
The purpose of this utility model is to design the single-phase different motor of a kind of plastic packaging, the stator core of this motor is surrounded by plurality of sections arc unit and several profiles of tooth, therefore when opening material, can adopt marker method to be washed into the material of strip, thereby reduced waste, saved cost.
The technical scheme that provides according to the utility model, the single-phase different motor of described plastic packaging comprises stator yoke portion and the stator teeth that fuses mutually, coil on stator teeth, rotor is arranged in stator teeth, it is characterized in that: stator yoke portion comprises plurality of sections arc unit, this plurality of sections arc unit by punch process into strips, the tooth that fuses with the arc unit is set on every section arc unit, the outside of plurality of sections arc unit fuses mutually, the inboard disconnection, form breach, coil is arranged on tooth, and the plurality of sections arc unit bending that is stripe-arrangement surrounds the stator yoke portion of annular, and the end face of the gap of adjacent two arc unit is fitted mutually, and splicing place of the arc unit that is positioned at head and the tail is welded to each other, in the stator yoke portion outside of annular plastic casing is arranged.
The self-clinching slotted eye is set on the arc unit; The self-clinching slotted eye is set on tooth.Coil is positioned on the insulation coil holder, and the insulation coil holder is enclosed within on the corresponding tooth.Rotor comprises rotating shaft and rotor core and aluminium ring, and rotor core is formed by stacking by the identical silicon steel sheet of some shapes, and rotating shaft is positioned at rotor core central authorities, in the rotor core both sides aluminium ring is arranged.On the every silicon steel sheet that constitutes rotor core, gap is set equably.On stator teeth, the tooth root between adjacent two teeth disconnects mutually.
Compare with existing stator,, wind the line then or rule becomes a motor stator because original stator core is circular punching out.The silicon steel material utilance can only reach about 45%, and the waste of copper coin seven envelope curve is also a lot.The utility model can the row of employing surround the annular stator earlier towards technology after winding the line on the strip, splice welding again, makes the utilance of silicon steel sheet reach 70%.Copper coin seven envelope curve saves about 30%, improves the various performance index of having warned motor, has reduced the manufacturing cost of motor.

Embodiment
As shown in the figure: the single-phase different motor of described plastic packaging comprises stator yoke portion and the stator teeth that fuses mutually, coil 2 on stator teeth, rotor 11 is arranged in stator teeth, stator yoke portion 1 comprises plurality of sections arc unit 1, this plurality of sections arc unit 1 by punch process into strips, the tooth 8 that fuses with arc unit 1 is set on every section arc unit 1, the outside of plurality of sections arc unit 1 fuses mutually, the inboard disconnection, form breach 9, coil 2 is arranged on tooth 8, plurality of sections arc unit 1 bending that is stripe-arrangement surrounds the stator yoke portion of annular, the end face of the gap of adjacent two arc unit 1 is fitted mutually, and splicing place of the arc unit 1 that is positioned at head and the tail is welded to each other, and in the stator yoke portion outside of annular plastic casing 14 is arranged.
Self-clinching slotted eye 3 is set on arc unit 1, self-clinching slotted eye 5 is set on tooth 8, so that the single arc unit 1 that is stamped to form by silicon steel sheet is superimposed as the thickness that needs with tooth 8 utilizations from catching groove 3,5 location.Coil 2 is positioned on the insulation coil holder 4, and insulation coil holder 4 is enclosed within on the corresponding tooth 10.Rotor 11 comprises rotating shaft 13 and rotor core and aluminium ring, and rotor core is formed by stacking by the identical silicon steel sheet of some shapes, and rotating shaft 13 is positioned at rotor core central authorities, in the rotor core both sides aluminium ring is arranged.On the every silicon steel sheet that constitutes rotor core, gap 12 is set equably.On stator teeth, the tooth root 6 between adjacent two teeth 10 disconnects mutually.
During manufacturing, with the insulation coil holder 4 that the premium insulation material is made, the coil holder 4 that will insulate again is enclosed within respectively on the corresponding tooth 8, and the coil winding machine of using appointment then forms stator winding at coiling 2 on insulation coil holder 4.The important role of insulation coil holder 4 is the winding former of the required usefulness of stator winding, be again and stator yoke portion, stator teeth between the material of high pressure resistant puncture.Motor stator is manufactured stator yoke portion and the stator teeth that is formed by stacking by some silicon steel sheets respectively, the good stator winding of coiling is enclosed within respectively on the tooth 8 of corresponding stator teeth, put into then in the stator yoke portion, use Plastic Package again in a plastic casing 14, make it become one and have that manufacturing process is simple, percent defective is low, and can reduce the high-quality monopole asynchronous motor of the cost of raw material.
Design about the small-power monopole asynchronous motor provided by the utility model, the general at present rule formula or the structure of Wound-rotor type small-power monopole asynchronous motor have been changed both at home and abroad, by original stator teeth, stator yoke portion is that unitary circular changes stator teeth into and stator yoke portion strikes out strip earlier, be bent into annular again, be enclosed within on the stator teeth around 4 one-tenth stator winding with the insulation coil holder then, by change to original stator structure, productivity ratio and various performance index have been improved greatly, save raw material, reduced the motor manufacturing cost.
