Abstract
The utility model relates to a stator punching for an air conditioning fan AC asynchronous motor. A hollow inner round hole is arranged in the middle of the stator punching, and a plurality of punching grooves are uniformly arranged between the excircle and the hollow inner round hole of the stator punching along the radial direction of the stator punching; the excircle diameter phi A of the stator punching is 92 to 98mm, wherein the incircle diameter phi B of the hollow inner round hole is 61 to 63mm, and the width C of a notch is 1.4 to 1.6mm; the width D of a groove shoulder is 3.944 to 4.144mm, and the height of the notch is 0.5 to 0.7mm; and the height F of the groove shoulder is 0.5 to 0.7mm, and the radius R of a groove top is 2.8 to 3.0mm. The utility model makes the tooth magnetic flux density and the yoke magnetic flux density of the stator punching tend to balance, reduces the electromagnetic noise of the motor, improves the efficiency of the motor, reduces the width of a stator punching ring, reduces the area of the punching groove, increases the utilization rate of the punching groove area, reduces the magnetic flux leakage coefficient and temperature rise of the motor, improves the service life of the motor, reduces the raw material consumption of motor windings and an iron core, and reduces the cost.
Description
Technical field
The utility model is a kind of stator punching of AC asynchronous motor, and particularly a kind of stator punching that is used for the air-conditioning fan AC asynchronous motor belongs to the improvement technology of the stator punching that is used for the air-conditioning fan AC asynchronous motor.
Background technology
Tradition is used for the stator punching 1 of air-conditioning fan AC asynchronous motor, as shown in Figure 1, circular hole 2 in the hollow has been made at the middle part of stator punching 1, be evenly distributed with the some punching grooves 3 that are provided with along the radial direction of stator punching in the cylindrical of stator punching and the hollow between the circular hole, general 92～the 98mm of the outside diameter of stator punching, the interior circular diameter of circular hole is generally 60 or 55mm in the hollow, through magnetic circuit analysis and calculating, there is following shortcoming in this stator laminating structure: 1, this stator punching is used on the air-conditioning fan AC asynchronous motor usually, and stator teeth 12 magnetic secret agreements are 12000, and yoke portion 11 magnetic secret agreements are 9000, obviously there is the close skewness phenomenon of magnetic, the close collocation of magnetic of tooth portion is unreasonable, the close higher and close problem on the low side of yoke portion magnetic of tooth portion magnetic influences electric efficiency and electromagnetic noise; 2, stator punching ring width broad, the punching groove area is bigger, 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.
The utility model content
The purpose of this utility model is to consider the problems referred to above and provides a kind of motor magnetic that can improve close, reduces winding and iron core raw material consumption, the stator punching that is used for the air-conditioning fan AC asynchronous motor of long service life.The utility model is reasonable in design, cost is low.
The technical solution of the utility model is: circular hole in the hollow has been made at the middle part of stator punching, is evenly distributed with the some punching grooves that are provided with along the radial direction of stator punching, the outside diameter of stator punching in the cylindrical of stator punching and the hollow between the circular hole
Be 92～98mm, the interior circular diameter of circular hole in the wherein said hollow
Be 61～63mm, slot opening C is 1.4～1.6mm, and groove shoulder breadth D is 3.944～4.144mm, and the high E of notch is 0.5～0.7mm, and groove shoulder height F is 0.5～0.7mm, and groove top radius R is 2.8～3.0mm.
Above-mentioned punching groove is provided with 24.
The utility model makes close and close the tending to balance of yoke portion magnetic of tooth portion magnetic of stator punching because the interior circular diameter of the interior circular hole of hollow of employing stator punching is 61～63mm and the structure of having optimized the slot part size, has reduced the electromagnetic noise of motor, has improved efficiency of motor; Reduce the stator punching ring width in addition, the punching groove area is reduced, improved the utilance of punching groove area, reduced the magnetic leakage factor and the temperature rise of motor, the useful life of having improved motor the raw material consumption of motor windings and iron core has been reduced, reduced cost.
