Abstract
The utility model discloses a stator punching sheet comprising a punching sheet body. Punching sheet grooves are evenly distributed on the internal circumference inside the punching sheet body. Circular heat radiating holes are evenly distributed on the external circumference of the punching sheet body, and diameter of each circular heat radiating hole is from 13 to 18mm. A motor adopting the punching sheet is great in heat radiating effect so that the service life is prolonged, weight of the motor is reduced and materials are saved simultaneously.
Description
Technical field
The utility model relates to machine field, especially relates to a kind of stator punching.
Background technology
Along with the development of technology, punching stator also improves constantly, the inner circle size of stator punching, flute profile size, and how many efficiency to motor has a great impact, and the stator punching noise in is past large, the shortcoming such as more than its enamelled wire consumption.
For this phenomenon, Chinese patent CN102801230 discloses a kind of stator punching, and this punching is by punch press punch forming on stator punching, port is distributed on stator punching, be 48 grooves, the punching of this structure, notch is little, saved the copper consumption of enamel insulated round copper wire, but when the punching of this structure is used, weight is large, heat radiation difficulty, long-term use can make winding temperature too high, causes shorten dynamo-electric useful life.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of lightweight, saves material, and perfect heat-dissipating, can extend the motor stator punching in useful life.
To achieve these goals, the utility model by the following technical solutions: a kind of stator punching, comprise punching body, on described punching body inner periphery, be evenly equipped with punching groove, on this punching body excircle, be evenly equipped with the circular louvre that diameter is 13-18mm.
As preferably, described louvre is 50-70 circular louvre.
As preferably, described punching groove is comprised of the exterior notch of arc and the inner tank mouths of circular arc.
As preferably, described punching groove lower port is trapezium structure.
As preferably, described punching groove is 40.
In sum, the utlity model has following advantage: adopt the motor of this punching, good heat dissipation effect, long service life, the while has also alleviated the weight of motor, has saved material.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1-2,, comprise punching body 1, on described punching body 1 inner periphery, be evenly equipped with punching groove 2, external peripheral surface is provided with synchronous notch 5, on this punching body 1 excircle, being evenly equipped with circular louvre 3 its diameters is 13-18mm, and this louvre has strengthened the radiating effect of motor, has alleviated the weight of motor, starting current is little, torque is large, has also saved material simultaneously, has saved cost.
Concrete, the quantity of described louvre 3 can be set to 50-70, and in the present embodiment, is set to 60, and the louvre of this quantity makes the heat dispersion of motor better, also can not cause punching easily to damage because louvre is excessive.
The shape of the punching groove 2 of design can be for multiple, and as shown in Figure 1, punching groove 2 is comprised of exterior notch 21 and inner tank mouths 22 shape that the present embodiment adopts, and this exterior notch 21 is arc, and this inner tank mouths 22 is circular arc.Adopt the notch of this shape to increase winding space, be conducive to stator and bear larger electric current.Another shape is as preferably as shown in Figure 2, and these punching groove 2 lower port are trapezium structure, and the punching groove notch of this trapezium structure is little, saves enamel insulated round copper wire copper consumption.
In order to improve the delivery efficiency of motor, noise decrease, punching groove 2 is made as 40.
Obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
