Abstract
The utility model relates to a stator lamination dedicated to an alternating current asynchronous motor. A hollow inner circular hole (2) is arranged in the middle of the stator lamination (1); a plurality of plate notches (3) which are arranged along the radial direction of the stator lamination (1) are distributed on the wall of the hollow inner circular hole (2); wherein, a plurality of unevenly distributed plate notches (3) are divided into a plurality of plate notch groups (4); and each plate notch group (4) includes two plate notches (3) the top radius of which is Rx, and two plate notches (3) the top radius of which is Ry. Since the dimension and distribution state of each notch are changed, so that the structure of an irregular notch is formed, the stator lamination can reasonably distribute the winding of the end of a motor, reduce the height of the end of the stator winding, reduce the loss of copper or aluminum in the process of the fabrication of the motor and reduce the usage of the materials of the winding and the iron core, thus better meeting the design requirement on motor material saving and energy efficiency enhancement. After a motor is designed and trial-produced with the stator lamination, the efficiency of the motor can be increased by 3 to 4 percent, and the usage of the materials of the windings and the iron core can be reduced by 15 to 30 percent.
Description
Technical field
The utility model is a kind of stator punching that is used for AC asynchronous motor, is specially adapted to the stator punching of the single-phase capacitor running AC asynchronous motor of air-conditioning fan, belongs to the renovation technique of the used stator punching of AC asynchronous motor.
Background technology
The stator punching that tradition is used for the single-phase capacitor running AC asynchronous motor is that the stator winding that coiling is good is put into the set groove of punching, and two ends unshakable in one's determination winding is called winding overhang, winding overhang consumed energy and do not produce useful magnetic field; The stator punching of existing conventional motor can not reduce winding overhang effectively, the operational efficiency of motor is also low, and the stator punching anufacturability of motor is poor, and the raw material consumption of making stator winding and iron core is big, motor cost is higher, can't reach the requirement that the single-phase capacitor running AC asynchronous motor saves material, raises the efficiency.
The utility model content
The purpose of this utility model is to consider the problems referred to above and a kind of efficiency that can improve motor is provided, reduces the stator punching that is used for AC asynchronous motor of winding and iron core raw material consumption.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, be distributed with the some punching grooves that are provided with along the radial direction of stator punching in the hollow on the hole wall of circular hole, wherein the punching groove of some non-uniform Distribution is divided into some punching groove groups, punching groove and 2 punching grooves that groove top radius is Ry that it is Rx that every group of punching groove group contains 2 groove top radiuses.
Above-mentioned each punching groove group along the circumferential direction is evenly distributed on the hole wall of circular hole in the hollow of stator punching.
Above-mentioned punching groove is provided with 24, is divided into into 6 groups of punching groove groups, and 6 groups of punching groove groups along the circumferential direction are evenly distributed on the hole wall of circular hole in the hollow of stator punching, and the angle in the adjacent punching groove group between the corresponding punching groove is 60 °.
Above-mentioned punching groove is provided with 16, is divided into into 4 groups of punching groove groups, and 4 groups of punching groove groups along the circumferential direction are evenly distributed on the hole wall of circular hole in the hollow of stator punching, and the angle in the adjacent punching groove group between the corresponding punching groove is 90 °.
The outside diameter of said stator punching
A is 93～128mm, the interior circular diameter of circular hole in the hollow
B is 52～76mm, and groove top radius is that the displacement size C between the center of circle of the center of circle of punching groove (3) of Rx and the punching groove that groove top radius is Ry is 3.2～5.6mm.
The utility model is owing to adopt size and the distribution that changes slot part, form the structure of special-shaped groove, therefore, its motor end winding that can rationally distribute, can shorten the stator winding end height dimension, and reduce the loss of motor copper or aluminium when making, reduce the raw material consumption of winding and iron core, thereby more can satisfy the designing requirement that motor saved material, improved efficiency.Through design trial-production, with the motor that this punching is made, can make efficiency of motor improve 3-4 percentage point, the raw material consumption of winding and iron core reduces 15-30%.The utility model is a kind of stator punching that is used for AC asynchronous motor ingenious, function admirable that designs, and is particularly suitable for making air-conditioning fan single-phase capacitor running AC asynchronous motor.
