Abstract

The utility model relates to a stator punching sheet for a copper and aluminium hybrid motor of a compressor. The stator punching sheet comprises a punching sheet body, wherein the punching sheet body comprises an inner hole matched with a rotor punching sheet; coil slots including both aluminum enameled wire slots and copper enameled wire slots are distributed at the periphery of the inner hole; the aluminum enameled wire slots are primary coil slots; the copper enameled wire slots are secondary coil slots; and the area of the primary coil slots is 1.1-1.7 times of that of the secondary coil slots. As the resistivity of aluminium is much larger than that of copper, during practical use, the desired diameter of the aluminum enameled wires is larger, the volume of the aluminum enameled wires is larger accordingly, and the area of the coil slots corresponding to the aluminum enameled wires is larger.

Description

A kind of stator punching of copper aluminium hybrid electric motor of compressor
Technical field
The utility model relates to a kind of compressor electric motor, especially relates to a kind of stator punching of compressor electric motor.
Background technology
Motor coil generally is made up of the copper enamelled wire, some motors are also arranged in order to practice thrift cost, adopts the aluminium enamel-covered wire coil; Like publication number is that the Chinese patent of CN201113577 discloses a kind of electric machine with aluminium winding, comprises stator, enamelled wire, and described enamelled wire is an aluminum steel; Described stator is made up of some stator punchings; This stator punching external diameter is 1.625~1.74 with the internal diameter ratio, and the groove height is 0.169~0.22 with the internal diameter ratio, and the number of poles of electric machine with aluminium winding is 4 utmost points.This utility model electric machine with aluminium winding overcomes the deficiency that the traditional copper wire motor is the integrated performance index decline of optimization aim with the cost, replaces the crucial electric conductor of copper cash as motor through aluminum steel, reduces the cost of enamelled wire significantly.During but reality was used, aluminium enamel-covered wire had easily and burns the characteristics that useful life is long; And volume is bigger; Be not suitable at some structural requirements comparatively compactly, and must use in the equipment of frequent starting, so present compressor electric motor generally is not consider electric machine with aluminium winding.In order to practice thrift cost, and guarantee to have found in its useful life, our company a kind of new copper aluminium hybrid electric motor; The main line of this motor adopts aluminum steel; By-pass adopts copper cash, because the thickness of copper cash and aluminum steel is different, just needs to adopt a kind of stator punching novel, that can adapt to this motor.
Summary of the invention
The utility model mainly is to solve the problem that existing in prior technology can not adapt to the stator punching of copper aluminium hybrid electric motor requirement, and a kind of copper aluminium hybrid electric motor that can be good at adapting to is provided, and is of moderate size, and is rational in infrastructure, the stator punching that the magnetic conduction ability is strong.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of stator punching of copper aluminium hybrid electric motor of compressor; It comprises the punching body, the punching body comprise one with the suitable endoporus of rotor punching, be distributed with the coil groove around the endoporus; This coil groove comprises aluminium enamel-covered wire groove and lead paint envelope curve groove; The aluminium enamel-covered wire groove ring recess of serving as theme, copper enamel-cover wire casing is the by-pass ring recess, the area of described main line ring recess be the by-pass ring recess 1.1-1.7 doubly.Because the resistivity of aluminium is than big many of the resistivity of copper cash, so in actual use, the diameter that aluminium enamel-covered wire need be done is bigger, so the volume of aluminium enamel-covered wire circle is bigger, and the area of the coil groove that it is corresponding is bigger.
As preferably, described main line ring recess has 16, divides equally in both sides up and down; Described by-pass ring recess has 8, divides equally in the left and right sides.
As preferably, the width of rebate of described main line ring recess is the 1.5-1.8 millimeter, and the width of rebate of by-pass ring recess is the 1.0-1.35 millimeter.For guaranteeing that the magnetic flux rate requires, width of rebate is more little good more, but for guarantee respectively aluminum coil and copper coil all can be convenient, install smoothly, need the above-mentioned width value of employing.
As preferably, the inside and outside pusher side of the notch of described main line ring recess and by-pass ring recess is equipped with chamfering.This structure makes enamelled wire when installing, can not sustain damage, and has improved the qualification rate of motor greatly.
The beneficial effect that brings of the utility model is; Solved the problem that existing in prior technology can not adapt to the stator punching of copper aluminium hybrid electric motor requirement, realized a kind of copper aluminium hybrid electric motor that can be good at adapting to, be of moderate size; Stator punching rational in infrastructure, that the magnetic conduction ability is strong.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is a kind of partial enlarged drawings of the utility model.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: as shown in Figure 1, the utility model is a kind of stator punching of copper aluminium hybrid electric motor of compressor, and it comprises punching body 1; Punching body 1 comprise one with the suitable endoporus of rotor punching, be distributed with the coil groove around the endoporus, this coil groove comprises aluminium enamel-covered wire groove 2 and lead paint envelope curve groove 3; Aluminium enamel-covered wire groove 2 ring recess of serving as theme; Copper enamel-cover wire casing 3 is the by-pass ring recess, and described main line ring recess has 16, divides equally in both sides up and down; Described by-pass ring recess has 8, divides equally in the left and right sides, and the area of described main line ring recess is 1.5 times of by-pass ring recess.Notch 4 width of main line ring recess are 1.65 millimeters, and the width of rebate of by-pass ring recess is 1.3 millimeters, and the inside and outside pusher side of the notch of main line ring recess and by-pass ring recess is equipped with chamfering.
So the present invention is of moderate size, rational in infrastructure, the characteristics that the magnetic conduction ability is strong.
