Description

The air conditioner motor stator punching
Technical field
The utility model relates to the air conditioner parts technical field, particularly a kind of air conditioner motor stator punching.
Background technology
Be energy savings, national standard has proposed enforceable high energy efficiency standard to air-conditioning, and motor also must improve energy-saving efficiency as the vitals of air-conditioning.Air conditioner motor stator punching material generally adopts silicon steel, how can not only improve the product efficiency while but also save material, and becomes the important problem in stator punching field.The middle part of stator punching commonly used is provided with interior circular hole, along the circumferential direction is evenly distributed with a plurality of stator slots between the cylindrical of stator punching and the interior circular hole.The air-conditioning power output is that Circularhole diameter is generally φ 55mm in the following motor stator punching of 65W, φ 58mm, φ 62mm etc., under the same conditions (as identical load, same rotational speed) these motor stator punchings otherwise since rotor little, induced electromotive force is little, moment is little, and efficient is low; Exist groove area little, difficult rule or iron core yoke portion are narrow, and magnetic is close big, easily produces defectives such as electromagnetic noise, has influenced the cost performance of air conditioner motor.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of air conditioner motor stator punching that can effectively improve energy-saving efficiency, design more rationally and can improve the air conditioner motor cost performance is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of air conditioner motor stator punching, comprise the stator punching body, the middle part of described stator punching body is provided with interior circular hole, along the circumferential direction be evenly distributed with a plurality of stator slots between the cylindrical of described stator punching body and the interior circular hole, the outside diameter φ A of described stator punching is 94~96mm, the diameter phi B of the interior circular hole of described stator punching is 58~62mm, the slot opening C of stator slot 2 is 1.8~2.2mm, groove shoulder breadth D is 4.8~5.2mm, the high E of notch is 0.5~0.7mm, groove shoulder height F is 0.6~0.8mm, stator facewidth G is 3~3.3mm, the high H of stator slot is 7.2~7.8mm, and groove top radius R is 3.4~3.6mm.
Compared with prior art, advantage of the present utility model is: this stator punching has been optimized the dimensional structure of stator slot, make stator punching yoke portion size more reasonable, make punching yoke portion magnetic close less, the phenomenon of the temperature rise that is difficult for producing magnetic saturation and causes, avoided having improved efficiency of motor owing to the close electromagnetic noise that produces greatly of yoke portion magnetic.In addition, the stator slot area is bigger, makes the copper factor of stator slot lower, is difficult for broken string like this when rule, is not prone to the phenomenon that causes turn-to-turn or high-voltage breakdown because of the coil damage.The design of this stator punching is reasonable more and can improve the air conditioner motor cost performance.
As preferably, the outside diameter φ A of described stator punching is 95mm, the diameter phi B of the interior circular hole of described stator punching is 60mm, the slot opening C of stator slot is 2mm, and groove shoulder breadth D is 5mm, and the high E of notch is 0.6mm, groove shoulder height F is 0.7mm, stator facewidth G is 3.2mm, and the high H of stator slot is 7.5mm, and groove top radius R is 3.5mm.Like this, the outside diameter moderate dimensions of stator punching, efficiency of motor height; The stator slot dimensional structure is reasonable, and groove area is big, and the copper factor of stator slot is lower, and punching yoke portion is big, has effectively avoided electromagnetic noise.
Description of drawings
The structural representation of Fig. 1 the utility model air conditioner motor stator punching.
The local structure for amplifying schematic diagram of the I portion of Fig. 2 the utility model air conditioner motor stator punching.
Among Fig. 1-2: 1, stator punching body, the outside diameter of φ A, stator punching, the diameter of the interior circular hole of φ B, stator punching;
2, stator slot, C, slot opening, D, groove shoulder breadth, E, notch height, F, groove shoulder height, G, the stator facewidth, H, stator slot height, R, groove top radius.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, 2, a kind of air conditioner motor stator punching, comprise stator punching body 1, the middle part of described stator punching body 1 is provided with interior circular hole, along the circumferential direction be evenly distributed with 24 stator slots 2 between the cylindrical of described stator punching body 1 and the interior circular hole, the outside diameter φ A of described stator punching is 95mm, the diameter phi B of the interior circular hole of described stator punching is 60mm, the slot opening C of stator slot 2 is 2mm, and groove shoulder breadth D is 5mm, and the high E of notch is 0.6mm, groove shoulder height F is 0.7mm, stator facewidth G is 3.2mm, and the high H of stator slot is 7.5mm, and groove top radius R is 3.5mm.
Like this, the stator outer diameter that matches with φ 60mm is the big 5mm of rotor diameter that matches for φ 55mm of the internal diameter of prior art on year-on-year basis, the big 2mm of rotor diameter that matches for φ 58mm of the internal diameter of prior art on year-on-year basis, the equal conditions lower rotor part is big, induced electromotive force is big more, staring torque and operation moment are big more, and efficient is high more, and cost is low more; In addition, the motor stamping internal diameter of prior art on year-on-year basis is that φ 62mm groove area is big, and under the same conditions, copper factor is low more, is not easy broken string during rule more, easy damaged and cause the phenomenon of turn-to-turn high-voltage breakdown not more between coil turn.And the yoke portion of this punching is 5.2mm than the internal diameter of prior art is the φ 62mm punching yoke big 0.2mm of portion, yoke portion is big more, magnetic circuit is wide more on the stator, magnetic is close more little, event is the phenomenon of the difficult temperature rise that produces magnetic saturation and cause of φ 62mm punching of prior art on year-on-year basis, can effectively avoid simultaneously, the magnetic close electromagnetic noise that greatly produce little, thereby improve the quality of products greatly owing to stator punching yoke portion.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model not only is confined to above embodiment, and its concrete structure allows variation.All various variations of being done in the protection range of the utility model independent claims are all in the utility model protection range.
