Abstract
The utility model relates to motor process technology and particularly relates to the technology to process a stator core for a plastic-sealed single-phase asynchronous motor. According to the technical proposal of the utility model, a stator tooth part is arranged inside the stator yoke. The stator core is characterized in that the stator tooth part is composed of a plurality of teeth which are evenly distributed along the circumference of the stator tooth part radially; grooves corresponding to the teeth of the stator tooth part are evenly distributed along the circumference of the inner track of the stator yoke; the ends of the teeth perfectly match with the grooves in shape, and the stator yoke and the teeth of the stator tooth part are fixed together through embedding of the ends of the teeth and the grooves. The stator yoke of the stator core is made up of a plurality of arc units, therefore when cutting material, the material can be cut to strips for the purposes of reducing waste and saving cost.
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 stator core of monopole asynchronous motor.
Background technology
Traditional stator core adopts the mode of full circle to open material opening when material mostly, promptly directly leaves circular one by one stator core raw material on a silicon steel plate, and this defective of opening the material mode is, can produce a lot of leftover pieces, causes very big waste.
Summary of the invention
The purpose of this utility model is to design a kind of stator core of monopole asynchronous motor, and the stator yoke portion of this stator core is surrounded by plurality of sections arc unit, therefore when opening material, can be split into the material of strip, thereby reduce waste, has saved cost.
The technical scheme that provides according to the utility model, in stator yoke portion, stator teeth is arranged, it is characterized in that: stator teeth is made up of several teeth of along the circumferential direction arranging radially equably, at the inner ring of stator yoke portion tooth corresponding groove with stator teeth is set equably along the circumferential direction, the shape of the increment of tooth and the shape of groove are coincide, and the tooth of stator yoke portion and stator teeth utilizes its increment and groove chimeric being fixed together mutually.
Stator yoke portion surrounds a full circle by plurality of sections arc unit, the outside of plurality of sections arc unit fuses mutually, and inboard the disconnection is after surrounding the stator yoke portion of annular, the end face of the gap of adjacent two arc unit is fitted mutually, and described groove shaped is formed in the inboard of arc unit.
The tooth root of adjacent two between cog disconnects mutually on the stator teeth.On the tooth of stator teeth, the hole is set.The hole of opening is set corresponding to the junction surface of adjacent two arc unit in stator yoke portion.
Compare with existing stator core, because original iron core is circular whole punching out, stock utilization can only reach about 45%, yoke portion of the present utility model and toothed portion is opened and can arrange and dash, the utilance of material can reach about 75%, save silicon steel material greatly, reduced the manufacturing cost of motor.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 list structure that several arc unit form of serving as reasons.
Fig. 3 is the structure chart of tooth.
Embodiment
As shown in the figure: stator teeth 13 is arranged in stator yoke portion 12, it is characterized in that: stator teeth 13 is made up of several teeth 2 of along the circumferential direction arranging radially equably, at the inner ring of stator yoke portion 12 tooth 2 corresponding groove 5 with stator teeth 13 are set equably along the circumferential direction, the shape of the increment 6 of tooth 2 and the shape of groove 5 are coincide, and stator yoke portion 1 utilizes its increment 6 and groove 5 mutual chimeric being fixed together with the tooth 2 of stator teeth 13.
Stator yoke portion 12 surrounds a full circle by plurality of sections arc unit 1, the outside of plurality of sections arc unit 1 fuses mutually, the inboard disconnection, after surrounding the stator yoke portion 12 of annular, the end face 10,11 of the gap of adjacent two arc unit 1 is fitted mutually, and described groove 5 is formed at the inboard of arc unit 1.
After the tooth 2 of stator teeth 13 was installed in the stator yoke portion 12, the tooth root 7 of 2 in adjacent two teeth still was in the state of mutual disconnection on the stator teeth 13.On the tooth 2 of stator teeth 13, hole 8 is set.The hole 4 of opening is set corresponding to the junction surface of adjacent two arc unit 1 in stator yoke portion 12,, forms stator yoke portion 12 so that the structure of strip is bent into cirque structure.
Stator core provided by the utility model is earlier the stator yoke portion 12 of stator core and stator teeth 13 separated into two parts, particularly stator yoke portion 12 subpunches are made a long strips that is formed by stacking by some silicon steel sheets that has calculated size in advance, the tooth 2 that then several has been equipped with the stator teeth 13 of stator winding utilizes respectively on the increment of dovetail and the arc unit 1 that groove structure is fitted in strip scientifically and rationally, curve an annular then, and, form a complete motor stator in annular splicing place firm welding.
