Abstract

The utility model relates to a stator punching for an alternating-current asynchronous motor of an air-conditioning fan. A hollow inner round hole is formed in the middle of the stator punching, and a plurality of punching grooves are uniformly distributed between the external circle and the hollow inner round hole of the stator punching in the radial direction of the stator punching; the external circle diameter phi A of the stator punching is 117 to 123 millimeters. The stator punching is characterized in that: the internal circle diameter phi B of the hollow inner round hole is 71 to 73 millimeters, and the width C of a notch is 1.5 to 1.9 millimeters; the width D of a groove shoulder is 3.0 to 3.4 millimeters, and the height E of the notch is 0.5 to 0.7 millimeter; and the height F of the groove shoulder is 0.5 to 0.7 millimeters, and the radius R of a groove top is 2.5 to 2.75 millimeters. The tooth magnetic flux density and the yoke magnetic flux density of the stator punching tend to balance, so that the electromagnetic noise of the motor is reduced, and the efficiency of the motor is improved; and in addition, the area of the punching groove is reduced, the utilization rate of the punching groove area is improved, the magnetic flux leakage coefficient and temperature rise of the motor are reduced, the service life of the motor is prolonged, the raw material consumption of motor windings and an iron core is reduced, and the cost is reduced.

Description

The stator punching that is used for the AC asynchronous motor of air-conditioning fan
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 AC asynchronous motor of air-conditioning fan belongs to the renovation technique of the stator punching of AC asynchronous motor.
Background technology
Tradition is used for the stator punching of the AC asynchronous motor of air-conditioning fan; Circular hole in the hollow has been made in the center; Be evenly distributed with the some punching grooves that are provided with along the radial direction of stator punching in the cylindrical of stator punching and the hollow between the circular hole, the general 117~123mm 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, to be used on the AC asynchronous motor of air-conditioning fan usually stator teeth 12 magnetic secret agreements be 12500 and yoke portion 11 magnetic secret agreements are 9200 to this stator punching, obviously has the close skewness phenomenon of magnetic, and the close collocation of magnetic of tooth portion is unreasonable; There is 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 H is bigger, makes the punching groove area bigger, and the utilance of punching groove area is about 66%; 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 make motor cost higher like this; 3, reduced the useful life of motor.
Summary of the invention
The purpose of the 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 of the AC asynchronous motor that is used for air-conditioning fan of long service life.The utility model is reasonable in design, cost is low.
The technical scheme of the utility model is: a kind of stator punching that is used for the AC asynchronous motor of air-conditioning fan; 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 in the cylindrical of stator punching and the hollow between the circular hole, and the outside diameter A of stator punching is 117~123mm; The interior circular diameter B that it is characterized in that circular hole in the said hollow is 71~73mm; Slot opening C is 1.5~1.9mm, and groove shoulder breadth D is 3.0~3.4mm, and the high E of notch is 0.5~0.7mm; Groove shoulder height F is 0.5~0.7mm, and groove top radius R is 2.5~2.75mm.
Above-mentioned punching groove is provided with 32.
The utility model advantage compared with prior art is: owing to adopt the interior circular diameter of the interior circular hole of hollow of stator punching is 71~73mm and the structure of having optimized the slot part size; Make stator punching make tooth portion magnetic close with close the tending to balance of yoke portion magnetic; Reduce the electromagnetic noise of motor, improved efficiency of motor; Reduce the punching groove area in addition, 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.
