The stator punching plate disclosed by the utility model has the advantages that since the shape of the punching plate groove is changed, the distribution of the magnetic field of the shoulder part and a yoke part of the groove is more reasonable, the noise of the motor is reduced, the efficiency of the motor is improved and the cost of the motor is reduced.
Description
Technical field
The utility model relates to a kind of stator punching that is used for fan motor of air conditioner.
Background technology
The stator punching that is used for fan motor of air conditioner generally comprises the punching body that is annular basically; The middle part of this punching body is formed with circular hole in the hollow, in the cylindrical of this punching body and hollow, is evenly distributed with the punching groove that several radially extend between the circular hole.The outside diameter of the punching body of traditional stator punching is generally 115～120mm; The diameter of circular hole is generally 65 or 68mm in the hollow; Through magnetic circuit analysis and calculating, there is following shortcoming in this stator laminating structure: 1, the close skewness of magnetic influences electric efficiency and electromagnetic noise; 2, stator punching ring width broad, the punching groove area is bigger, and the utilance of punching groove area is about 65%; Because the punching groove fails to make full use of; Cause electric machine temperature rise and magnetic leakage factor to increase, therefore, for increasing magnetic flux and reducing temperature rise; Winding and iron core raw material consumption certainly will will increase, and motor cost is increased; 3, reduced the useful life of motor.Fan motor of air conditioner is of a great variety on market, and consumption is very big, dog-eat-dog, and the user requires increasingly high to noise pollution, and each motor production firm reduces the noise of motor when exhausting one's ability to reduce cost.
The utility model content
The utility model technical problem to be solved is when practicing thrift cost, to optimize the electromagnetic noise of motor.
For solving the problems of the technologies described above; Technical scheme below the utility model has adopted: a kind of stator punching that is used for fan motor of air conditioner is provided; Comprise the punching body that is annular basically, the middle part of this punching body is formed with circular hole in the hollow, in the cylindrical of this punching body and hollow, is evenly distributed with the punching groove that several radially extend between the circular hole; The outside diameter Φ A of said punching body is 115 ~ 125mm, and the diameter of phi B of circular hole is 66 ~ 70mm in the said hollow; Said punching groove has notch, groove shoulder, groove body and groove top; Wherein, said notch is rectangular, and its width C is 1.6 ~ 2.0mm, and height E is 0.7 ~ 0.9mm; Said groove shoulder is trapezoidal, and its length D that goes to the bottom is 4.22 ~ 4.42mm, and height F is 0.7 ~ 0.9mm; Said groove body is trapezoidal, and its height G is 9.5 ~ 9.7mm; Said groove top semicircular in shape, its radius R is 3.21 ~ 3.61mm.
Preferably, said punching groove has 24.
Compare with the traditional stator punching, the stator punching of the utility model has following advantage:
1. reduce the area of stator punching groove, reduced the consumption of copper cash;
2. strengthened stator punching groove shoulder breadth degree and stator yoke portion size, it is close to reduce stator each several part magnetic, makes close being more evenly distributed of stator each several part magnetic, has improved electric efficiency;
3. reduce the loss of motor copper or aluminium when making, reduced the raw material consumption of winding and iron core;
4. because close distribution of magnetic and collocation improve, improve the utilance of stator slot area, reduced the magnetic leakage factor and the temperature rise of motor, the useful life of having improved motor.
Description of drawings
Fig. 1 is the structural representation of a kind of preferred embodiment of the utility model stator punching.
Fig. 2 is the I partial enlarged drawing of Fig. 1.
Embodiment
As depicted in figs. 1 and 2; The stator punching that is used for fan motor of air conditioner of the utility model has comprised the punching body that is annular basically; The middle part of this punching body is formed with circular hole in the hollow, in the cylindrical of this punching body and hollow, is evenly distributed with the punching groove that several radially extend between the circular hole.The outside diameter Φ A of punching body is 115 ~ 125mm, and the diameter of phi B of circular hole is 66 ~ 70mm in the said hollow; Said punching groove has notch, groove shoulder, groove body and groove top; Wherein, said notch is rectangular, and its width C is 1.6 ~ 2.0mm, and height E is 0.7 ~ 0.9mm; Said groove shoulder is trapezoidal, and its length D that goes to the bottom is 4.22 ~ 4.42mm, and height F is 0.7 ~ 0.9mm; Said groove body is trapezoidal, and its height G is 9.5 ~ 9.7mm; Said groove top semicircular in shape, its radius R is 3.21 ~ 3.61mm.
As a more excellent embodiment, said punching groove has 24.The outside diameter Φ A of punching body is 120mm, and the diameter of phi B of circular hole is 68mm in the hollow; The width C of the notch of said punching groove is 1.8mm, and height E is 0.8mm; The length D that goes to the bottom of groove shoulder is 4.32mm, and height F is 0.8mm; The groove body is trapezoidal, and its height G is 9.6mm; The radius R on groove top is 3.41mm.
The utility model stator punching makes groove shoulder and yoke portion Distribution of Magnetic Field more reasonable through the flute profile of change punching groove, has reduced motor noise, has improved electric efficiency, has reduced motor cost.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model inventive concept; Can also make some distortion and improvement, these all belong to the protection range of the utility model.
