Abstract
The invention relates to a component structure of a four-shaded pole asynchronous motor stator, in particular to a four-shaded pole asynchronous motor stator. The motor stator comprises an integrated stator with an inner bore at the center thereof; four empty slots are evenly distributed on a stator entity at the periphery of the inner bore; entities among the four empty slots are used for installing the four poles of the iron cores of four groups of coils; the outline of an inner bore section corresponding to the inner opening of each pole of the iron core is a curve section; and a clearance between the curve section and the external outline of a rotor at the center gradually changes from small to large sizes. The four-shaded pole asynchronous motor stator of the invention can improve motor efficiency and motor torque.
Description
Technical field
The present invention relates to a kind of modular construction of shaded pole asynchronous motor, specifically is a kind of four-shaded pole asynchronous motor stator.
Background technology
The stator core of common four-shaded pole asynchronous motor generally includes the housing that a center has the criss-cross inside casing of endoporus and is positioned at the annular of inside casing periphery, four groups of stator coils are extremely gone up around criss-cross four of inside casing, inside casing are pressed in the housing inner ring chimeric fixing after the coil winding on the inside casing is finished again.Course of work rotor rotates in the endoporus at inside casing center.There is following defective in the stator of this structure: 1, because iron core is the branch body structure, the inevitable certain magnetic loss that brings has reduced electric efficiency; 2, during machine operation, produce magnetic field behind the coil indirect current, its N, S extremely constantly change, and stator four utmost points of four groups of coil correspondences in mouthful connect as one, it is not thorough to make that N between the two neighboring pole, the S utmost point change, and influences each other, thereby increased in-fighting, reduced efficient; 3, because the installing hole in iron core bight is a through hole, make that the air gap on the magnetic circuit is bigger, increased magnetic loss, reduced efficient; 4, each of iron core extremely goes up the outstanding upper and lower surface of iron core of the short-circuited conducting sleeve that is provided with, make coil brace can not be close to iron core, thereby increased the size of coil brace, and then made that enamelled wire number of turns when coiling of same length is less, be unfavorable for the raising of the torque of power of motor.
Summary of the invention
Technical problem to be solved by this invention is that a kind of four-shaded pole asynchronous motor stator that can improve electric efficiency, improve Motor torque is provided.
Motor stator of the present invention comprises that a center has the stator of the integral body of endoporus, be evenly distributed with four dead slots on the stator entity of described endoporus periphery, entity between four dead slots is iron core four utmost points that are used for installing four groups of coils, one section internal bore profile of each utmost point internal orifice correspondence of iron core is one section curve, and the gap between the rotor outline at this section curve and center is extremely gradually changed greatly by little.
Described iron core four utmost point internal orifice profiles are cut apart by four slits that are communicated with endoporus and dead slot, form independently four sections.
Four of described iron core is extremely gone up the thickness of the thickness of the short-circuited conducting sleeve installation position that short-circuited conducting sleeve is installed less than the iron core main body, makes short-circuited conducting sleeve that top and base plane that the back short-circuited conducting sleeve does not protrude in iron core are installed.
The installing hole in described iron core bight is the big and less stepped hole of stage casing diameter of top diameter.
Beneficial effect of the present invention is embodied in: 1, because stator design is as a whole, reduces like this and treat under the split-type structural to be bumped into after coil winds in the stator and the magnetic loss that brings again, thereby can improve electric efficiency.2, because the air gap of stator internal orifice and rotor is gradual change, the rotation that is beneficial to rotor more, the moment of torsion of motor obviously increases.3, during machine operation, N, S that iron core four utmost points of coil are installed extremely constantly change, and be more thorough when making N between the two neighboring pole, the variation of the S utmost point because the stator internal orifice is divided into four parts by slit, thereby can reduce in-fighting, raises the efficiency.4, the installing hole of iron core is provided with stepped hole, can fully reduce the air gap on the magnetic circuit, reduces magnetic loss as much as possible, raises the efficiency.5, because the thickness of short-circuited conducting sleeve installation position is less, make the end face and the bottom surface that can not protrude in iron core after short-circuited conducting sleeve is installed, the corresponding height that has just reduced coil brace, the following number of turns that winds up following of enamelled wire specification, situation that length is identical just increases, and then can improve the power output of motor and the torque of motor.

Embodiment
As shown in the figure, this motor stator comprises that a center has the stator 1 of the integral body of endoporus 11, be evenly distributed with four dead slots 12 on the stator entity of described endoporus periphery, entity between four dead slots is iron core four utmost points 13 that are used for installing four groups of coils 2, one section internal bore profile of each utmost point internal orifice correspondence of iron core is one section curve 14, and the gap between rotor 3 outlines at this section curve and center is extremely gradually changed greatly by little.Iron core four utmost point internal orifice profiles are communicated with endoporus 11 by four and cut apart with the slit 15 of dead slot 12, form independently four sections.Four of iron core is extremely gone up the thickness of the thickness of the short-circuited conducting sleeve installation position 16 that short-circuited conducting sleeve is installed less than the iron core main body, makes short-circuited conducting sleeve that top and base plane that the back short-circuited conducting sleeve does not protrude in iron core are installed.The installing hole 17 in iron core bight is the big less stepped hole of stage casing diameter of top diameter.
