Abstract

The utility model relates to a stator punching of an alternating current asynchronous motor used for an air conditioning fan. The middle of the stator punching is provided with an inner hollow round hole, the inside edge of the stator punching is provided with a plurality of punching slots along the radial direction of the inner hollow round hole, and the excircle diameter A of the stator punching is 92-98mm. The stator punching is characterized in that the inner circle diameter B of the inner hollow round hole is 59-61mm; the notch width C of each punching slot is 1.9-2.1mm; the width D of the slot shoulder is 5.0-5.2mm; the notch height E is 0.5-0.7mm; the height F of the slot shoulder is 0.6-0.8mm; and the radius R of the slot top is 3.4-3.6mm. In the utility model, the dimensional structure of the stator punching slot is optimized, the diameter of the inner hollow round hole is enlarged, the magnetic density of the tooth part and the yoke part of the stator punching tends to be balanced, the electromagnetic noise of a motor is reduced, and the efficiency of the motor is improved. Meanwhile, the utilization rate of the area of the punching slot is improved by reducing the area of the punching slot, the magnetic leakage factor and temperature rise of the motor are reduced, the service life of the motor is prolonged, the reliability of frequent start is improved, and the winding consumption of the motor is also decreased.

Description

The stator punching that is used for the AC asynchronous motor of air-conditioning fan
Technical field
The utility model relates to 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 improvement technology of the stator punching of AC asynchronous motor.
Background technology
At present, the stator punching of the fan electromotor of commercially available air-conditioning as shown in Figure 1, the middle part punching press of stator punching has circular hole in the hollow, radial equipartition has 24 punching grooves on the edge of the interior circular hole of stator punching ring hollow, general 92~the 98mm of the outside diameter of stator punching, the diameter of circular hole is generally 55mm in the hollow, through magnetic circuit analysis and calculating, there is following shortcoming in the stator punching of this structure: 1, the magnetic secret agreement of stator teeth 12 is 12000, and the magnetic secret agreement of yoke portion 11 is 9000, there is the close higher and close problem on the low side of yoke portion magnetic of tooth portion magnetic, the close skewness phenomenon of magnetic is very obvious, causes electric efficiency not high, electromagnetic noise is bigger; 2, the ring width H of stator punching is bigger, the area of punching groove is bigger, the utilance of punching groove area is about 61%, because the punching groove fails to make full use of, and causes electric machine temperature rise bigger, magnetic leakage factor increases, in order to increase magnetic flux and to reduce temperature rise, usually can adopt the mode that increases winding and iron core raw material consumption to improve magnetic loading, to guarantee the reduction of the constant and electric machine temperature rise of motor overload ability, the result has increased the cost of motor again; 3, because the punching temperature rise is higher, can reduce the useful life and the operational reliability of motor.
Summary of the invention
The purpose of this utility model be to consider the problems referred to above and provide a kind of by the slot part size of optimizing stator punching reach balanced motor magnetic close, reduce electromagnetic noise and winding raw material consumption, prolong the stator punching of the AC asynchronous motor that is used for air-conditioning fan in motor useful life.
The technical solution of the utility model is: a kind of stator punching that is used for the AC asynchronous motor of air-conditioning fan, the middle part of stator punching offers circular hole in the hollow, radially be provided with several punching grooves in the inner side edge edge of stator punching along circular hole in the hollow, the outside diameter A of stator punching is 92~98mm, the interior circular diameter B that it is characterized in that circular hole in the hollow is 59~61mm, the width of rebate C of punching groove is 1.9~2.1mm, groove shoulder breadth degree D is 5.0~5.2mm, notch height E is 0.5~0.7mm, groove shoulder height degree F is 0.6~0.8mm, and groove top radius R is 3.4~3.6mm.
Above-mentioned punching groove is evenly distributed on the inner side edge of stator punching along last.
Above-mentioned punching groove is provided with 24.
The utility model has been optimized the dimensional structure of stator punching groove, and the diameter of circular hole in the hollow is increased to 59~61mm, makes close and close the tending to balance of yoke portion magnetic of tooth portion magnetic of stator punching, has obviously reduced the electromagnetic noise of motor, has improved efficiency of motor; Simultaneously, improved the utilance of punching groove area by the area that reduces the punching groove, the magnetic leakage factor and the temperature rise of motor have not only been reduced, the useful life of motor and the reliability of frequent starting have been improved, and reduced the winding consumption of motor, obviously reduced the cost of motor, reasonable in design, function admirable.
