Abstract
The invention provides an air-conditioner motor stator sheet comprising a stator sheet yoke part, stator sheet tooth parts and stator sheet slots. Each stator sheet slot comprises a stator sheet slot port and a stator sheet slot body. The air-conditioner motor stator sheet is characterized in that the shape of the stator sheet slots is special-shaped. The center line of the stator sheet slot port is through the internal hole of the stator sheet. The stator sheet slot port is arranged at one side of the stator sheet slot body in an offset way. The air-conditioner motor stator sheet is suitable for direct winding of distributed windings, and mechanical automatic winding production is adopted so that production labor cost is reduced, work efficiency is enhanced, length of the winding end part is reduced, material cost is saved and winding loss is reduced and thus motor efficiency is enhanced; and damage to the paint layer of the surface of enameled wires is reduced and safety performance and the service life of a motor are enhanced.
Description
Technical field
The present invention relates to air conditioner and manufacture field, particularly relate to a kind of motor of air conditioner stator piece.
Background technology
In current air conditioner manufacturing, need the motor producing large batch of various different performance, different size, and the major part of motor is stator and rotor, particularly the competition of the sector is very large, how to reduce production cost, become the major issue of each manufacturer thinking.
Traditional stator core, the winding of motor adopts coil-inserting method, first enamelled wire coiling on winding former had the coil of definite shape and the number of turn, again enamel wire coil is taken off from winding former, enamel wire coil good for coiling is embedded in stator core slot, easily elongate in rule process and scratch enameled wire coat, motor turn-to-turn short circuit may be caused, there is potential safety hazard, the unnecessary height of end winding, both wasted material and turn increased loss.
Summary of the invention
Object of the present invention will provide a kind of motor of air conditioner stator piece exactly, comprise stator piece yoke portion, stator piece teeth portion, stator film trap, stator film trap comprises stator piece notch and stator film trap body, it is characterized in that, the flute profile of described stator film trap is special-shaped slot, and the center line of stator piece notch crosses the center of circle of stator piece endoporus; The location bias of stator piece notch is in the side of stator film trap body.Be applicable to the direct coiling of distributed winding, mechanization automatic winding is adopted to produce, reduce input of labor cost, improve work efficiency, reduce winding overhang length, both saved material cost and again reduced winding loss, and improved electric efficiency, reduce the damage of enamelled wire surface enamelled coating, improve security performance and the useful life of motor.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1: traditional stator piece structural representation
Fig. 2: stator piece structural representation of the present invention
In figure: 1-1, stator piece yoke portion, 1-2, stator piece teeth portion, 1-3, stator film trap, 1-4, stator piece notch, 1-5, stator film trap body; 2-1, stator piece yoke portion, 2-2, stator piece teeth portion, 2-3, stator piece special-shaped slot, 2-4, stator piece abnormity notch, 2-5, stator film trap body
Embodiment
As shown in Figure 1, traditional stator piece comprises stator piece yoke portion 1-1, stator piece teeth portion 1-2, stator film trap 1-3, stator piece notch 1-4, stator film trap 1-3 comprises notch 1-4 and stator film trap body 1-5, stator piece notch 1-4 is positioned on the center line of stator film trap 1-3, and stator piece flute profile can be flat-bottom slot, round bottomed vessel, dovetail groove.
As shown in Figure 2, motor stator slice of the present invention, comprises stator piece yoke portion 2-1, stator piece teeth portion 2-2, stator film trap 2-3, and stator film trap 2-3 comprises stator piece notch 2-4 and stator film trap body 2-5, it is characterized in that, the flute profile of described stator film trap 2-3 is special-shaped slot; The center line of stator piece notch 2-4 crosses the center of circle of stator piece endoporus; The location bias of stator piece notch 2-4 is in the side of stator film trap body 2-5.Be applicable to the direct coiling of distributed winding, adopt mechanization automatic winding to produce, reduce input of labor cost, improve work efficiency; Reduce winding overhang length, both saved material cost and again reduced winding loss, and improved electric efficiency, reduce the damage of enamelled wire surface enamelled coating, improve security performance and the useful life of motor.
Be the first coiling good coil by regulation geomery on winding former during traditional stator piece rule, and then embed in stator slot, stator has higher end winding, and the electromagnetic performance of end winding to motor does not produce effect, wastes enamelled wire; Easily elongate during rule and scratch paint film, motor turn-to-turn short circuit can be caused to have potential safety hazard.It is coiling that motor stator slice of the present invention changes rule, and enamelled wire directly around the teeth portion of stator core by coil winding machine, is not easily elongated and scratches paint film, improve the quality of winding, the motor stator enamelled wire end of direct coiling is less, saves a large amount of enamelled wires, reduces loss.The area of stator piece air-gap disc is comparatively large, and air gap flux density is low, and noise is low, and stator winding enamelled wire wire diameter reduces, and the number of turn reduces, and saves enamelled wire.
With 24 grooves as an example, but other groove number is also in protection scope of the present invention motor stator film trap of the present invention.
