Abstract
The invention provides a stator structure without a stator end plate and a pressing ring. The stator structure comprises stator punching sheets and stator punching sheets with welding holes, wherein a plurality of small holes are punched in surfaces of the stator punching sheets with the welding holes; the stator punching sheets with the welding holes are laminated together and spot-welded into stator punching sheet bodies through the small holes; and the stator punching sheets are laminated between two of the stator punching sheet bodies to form a stator iron core. The stator structure without the stator end plate and the pressing ring has the advantages that: the stator punching sheets are spot-welded into the stator punching sheet bodies having certain thickness through the small holes; the stator punching sheet bodies have certain mechanical strength; and when the stator punching sheets are laminated, the stator punching sheet bodies are put at two ends to replace the stator end plate and the pressing ring, so the manufacturing cost of a motor is greatly saved.
Description
Technical field
The present invention relates to a kind of stator structure, specifically is a kind of stator structure that adopts the stator punching that substitutes motor stator end plate and trim ring.
Background technology
Shown in Fig. 1～4, the motor that H315 is above, stator core is when laminating, often to add stator pressing ring 2 and stator end plate 3, stator pressing ring 2 is to forge by certain thickness band steel to form, and stator end plate 3 is to be formed by blanking die and stamping die punching by certain thickness steel plate, and the purpose that adds stator pressing ring 2 and stator end plate 3 is to prevent that stator core tooth portion when laminating from flicking excessive, influence motor performance, as the no-load current of motor, the electromagnetic noise of motor etc.Flute profile with the stator punching 1 identical number of teeth is arranged on the stator end plate 3, different stator punchings 1 need different stator end plates, will make many stator end plate 3 blanking dies and stamping die like this, it is high that Mold Making becomes, thus, use stator end plate 3 and stator pressing ring 2 that the manufacturing cost of motor will be increased greatly.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, a kind of New-type electric machine stator punching is provided, make the stator structure of no traditional stator end plate and trim ring.
According to technical scheme provided by the invention, the stator structure of described no stator end plate and trim ring comprises stator punching, the stator punching that also comprises the tape welding hole, the stator punching surface in described tape welding hole dashes a plurality of apertures, the stator punching in multi-disc tape welding hole overlaps together and becomes the stator punching body by aperture spot welding, laminates a plurality of stator punchings in the middle of two described stator punching bodies and forms stator core.
Aperture on the stator punching in described tape welding hole is that the center of circle is circle distribution with the center of circle of the stator punching in tape welding hole.
Aperture on the stator punching in described tape welding hole is distributed between each tooth pitch of stator punching tooth portion in tape welding hole.
Advantage of the present invention is: a plurality of stator punchings are formed certain thickness stator punching body by aperture spot welding, this stator punching body has certain mechanical strength, when stator punching laminates, be placed on two ends, replace stator end plate and stator pressing ring, thereby saved the motor manufacturing cost greatly.

Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described.
Stator core commonly used is overrided to form by stator punching 1, stator pressing ring 2, stator end plate 3 as shown in Figure 4.
As shown in Figure 5, the present invention includes the stator punching 4 in stator punching 1 and tape welding hole, stator punching 4 surfaces in described tape welding hole dash a plurality of apertures, the stator punching 4 in multi-disc tape welding hole overlaps together and becomes 5, two described stator punching bodies of stator punching body, 5 centres by aperture spot welding and laminates a plurality of stator punchings 1 formation stator cores.
Manufacture craft is: the stator punching 4 in tape welding hole is to be formed by the punching of stator punching gangdie, in the circumference upper punch of its surperficial certain diameter a plurality of apertures is arranged, and between each tooth pitch of its tooth portion, dashing has a plurality of apertures.Stator punching 4 with multi-disc tape welding hole overlaps together again, and becoming by aperture spot welding (solder joint 6) with spot welding machine has certain thickness stator punching body 5, as Fig. 6.When stator punching laminated, lower floor put a stator punching body 5, and the centre stacks several stator punchings that does not have aperture 1, put a stator punching body 5 again on the upper strata, was overrided to form stator core by forcing press.
The stator core that is overrided to form by this kind method, tooth portion flicks very little, not only having eliminated tooth portion and flicked the shortcoming that the excessive motor performance that causes descends, and saved the motor manufacturing cost greatly, is a kind of not only economy but also the alternative motor stator end plate of practicality and the method for trim ring.
Claims (3)
