Abstract
The utility model relates to a stator punching sheet for a dehumidifier motor. A hollow inner circular hole is arranged in the middle of the stator punching sheet and a plurality of punching sheet grooves are uniformly arranged between the top circle of the stator punching sheet and the hollow inner circular hole along the radial direction of the stator punching sheet, wherein the diameter Phi A of the top circle of the stator punching sheet is 62-68mm, the diameter Phi B of the inner circle of the hollow inner circular hole is 32-38mm, the groove width is 1.9-2.1mm, the groove shoulder width D is 4.1-4.3mm, the groove height E is 0.5-0.7mm, the groove shoulder height F is 0.5-0.7mm. and the groove top radius R is 3.0-3.2mm. The tooth magnetic flux density of the stator punching sheet and the yoke magnetic flux density approach equilibrium and the electromagnetic noise of the motor is reduced, the motor efficiency is increased; in addition the area of the punching sheet groove is reduced, the utilization factor of the punching sheet groove area is increased, the leakage coefficient and temperature rise of the motor are reduced, the service life of the motor is increased, the raw material usage of the machine winding and iron core is reduced, the cost is reduced and the stator punching sheet in smaller outer diameter can prevent deformation and be easily produced.
Description
Technical field
The utility model is a kind of stator punching of motor, and particularly a kind of stator punching that is used for the dehumidifier motor belongs to the improvement technology of the stator punching that is used for the dehumidifier motor.
Background technology
Tradition is used for the stator punching of dehumidifier motor, 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, general 72～the 82mm of the outside diameter of stator punching, through magnetic circuit analysis and calculating, outside diameter is that the stator punching of 72～82mm is used for existing on the dehumidifier motor following shortcoming: 1, tooth portion magnetic is close higher, yoke portion magnetic is close on the low side, electric efficiency is low, and electromagnetic noise is big; 2, 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, be bipolar machine because dehumidifier generally uses, power is less, and all adopt big external diameter to make easily that iron core thickness is low to cause distortion, are unfavorable for making.
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 dehumidifier motor that is easy to make.
The technical solution of the utility model is: a kind of stator punching that is used for the dehumidifier motor, 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, the outside diameter of wherein said stator punching in the cylindrical of stator punching and the hollow between the circular hole
Be 62～68mm, the interior circular diameter of circular hole in the hollow
Be 32～38mm, slot opening C is 1.9～2.1mm, 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 3.0～3.2mm.
Above-mentioned punching groove is provided with 16.
The utility model is because to adopt the outside diameter of stator punching be 62～68mm, the interior circular diameter of circular hole in the hollow
Be 32～38mm and the structure of having optimized the slot part size, make close and close the tending to balance of yoke portion magnetic of tooth portion magnetic of stator punching, reduced the electromagnetic noise of motor, improved efficiency of motor; Reduced the punching groove area in addition, improved the utilance of punching groove area, the magnetic leakage factor and the temperature rise of motor have been reduced, improved the useful life of motor, the raw material consumption of motor windings and iron core is reduced, reduced cost, and adopted the stator punching of less external diameter can prevent its distortion, be easy to make.
