Abstract

The utility model relates to a stator punching sheet for an air conditioner fan AC asynchronous motor. The middle of the stator punching sheet is provided with a hollow inner circular hole; a plurality of punching sheet grooves are uniformly distributed between an external circle of the stator punching sheet and the hollow inner circular hole along the radial direction of the stator punching sheet; the diameter of the external circle of the stator punching sheet Phi A is 107-113mm; the diameter of the inner circle of the hollow inner circular hole Phi B is 65-71mm; the width of a groove opening C is 1.6-1.8mm; the width of a groove shoulder is 4.1-4.3mm; the height of the groove opening E is 0.5-0.7mm; the height of the groove shoulder F is 0.5-0.7mm; and the radius of a groove top R is 2.9-3.1mm. The stator punching sheet of the utility model has nearly balanced magnetic flux density in the gear part and the yoke part, which reduces the electromagnetic noise of the motor, improves the efficiency of the motor, decreases the area of the punching sheet groove, improves the utilization rate of the area of the punching sheet groove, reduces the coefficient of magnetic dispersion and temperature rise of the motor, improves the service life of the motor, reduces the using amount of the raw materials of motor windings and iron cores, and lowers cost.

Description

The stator punching that is used for the air-conditioning fan AC asynchronous motor
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 of the AC asynchronous motor of air-conditioning fan, circular hole in the hollow has been made at the middle part of stator punching, 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 120mm of the outside diameter of stator punching, this stator punching is used for existing on the air-conditioning fan AC asynchronous motor following shortcoming: 1, tooth portion magnetic is close higher, yoke portion magnetic is close on the low side, and electric efficiency is low, and electromagnetic noise is big; 2, punching ring width broad, the punching groove area is bigger, and the groove area utilance is lower, because groove area fails to make full use of, cause electric machine temperature rise and magnetic leakage factor to increase, therefore, need to increase winding and iron core raw material consumption and reduce temperature rise and increase magnetic flux, increased motor cost like this; 3,, reduced motor useful life because the punching temperature rise.
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 described stator punching in the cylindrical of stator punching and the hollow between the circular hole A is 107~113mm, the interior circular diameter of circular hole in the hollow B is 65~71mm, and slot opening C is 1.6~1.8mm, and groove shoulder breadth D is 4.1~4.3mm, 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 2.9~3.1mm.
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 to adopt the outside diameter of stator punching be 107~113mm and the structure of having optimized the slot part size, has reduced the electromagnetic noise of motor, has 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.
