Abstract
The invention discloses a stator for efficient and super-efficient three-phase asynchronous motors, which comprises a plurality of stator core sheets and two pressing sheets positioned at the end parts of the stator core sheets, wherein a plurality of W -shaped notches are arranged on the excircle circumferences of the stator core sheets and the pressing sheets at intervals, meanwhile, the stator formed by the overlapping of the stator core sheets and the two pressing sheets is provided with an axial W-shaped welding groove formed by the overlapping of the W-shaped notches on the excircle circumferences, the stator core sheets and the two pressing sheets are fixed in the W-shaped welding groove in a welding manner to ensure that the production efficiency of the stator is greatly improved, the materials used in a stator core manufacturing process are reduced, and the cost is lowered, and ensure that the mechanical strength of a stator core and the accuracy of the verticality can be improved, the lamination coefficient of the stator core sheets is increased, the stray loss, the core loss and the eddy-current loss are decreased, thus the output efficiency of a motor is improved.
Description
Technical field
The present invention relates to the motor technology field, be specifically related to a kind of stator of efficient, ultra high efficiency threephase asynchronous.
Background technology
The use of motor is quite general in daily life, and people are also constantly improving and improving the manufacturing process of motor and motor according to the difference of motor use occasion simultaneously.
In the manufacturing process of stator of traditional threephase asynchronous, employing be some cramp grooves of processing on the cylindrical circumference of stator, place the stator cramp in the groove, with stator cramp fixed stator lamination.
The shortcoming of above-mentioned this technology is that the perpendicularity precision of the mechanical strength of stator core and stator core is not high, the lamination coefficient of stator core sheet is not high, cause stray loss, core loss, the eddy current loss of motor bigger, and employed material is more in the stator core manufacturing process, cost is higher, and motor delivery efficiency and production efficiency are also not high enough in addition.
How improving the shortcoming and defect of prior art, is that motor manufacturing technical staff endeavours one of content of studying always.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the present invention aims to provide a kind of stator efficient, the ultra high efficiency threephase asynchronous that is used for, to improve the mechanical strength and the verticality precision unshakable in one's determination of motor stator-core, improve the lamination coefficient of motor stator-core sheet, reduce employed material in the stator core manufacturing process, and then reduce cost, and improve the efficient of the motor delivery efficiency and the manufacturing.
The technical scheme that realizes above-mentioned purpose is, a kind ofly be used for stator efficient, the ultra high efficiency threephase asynchronous, comprise that some stator core sheets and two are positioned at the compressing tablet of some stator core sheets end, on the cylindrical circumference of described stator core sheet and compressing tablet, all have several " W " shape notches at interval, and, some stator core sheets and the formed stator of two compressing tablet closed assemblies, some axial " W " shape welding grooves of the stacked formation of its round outside Zhou Shangyou " W " shape notch.
Between the described stator core sheet and fixing between stator core sheet and the compressing tablet, thereby form a rigid canister iron core by in axial " W " shape welding groove, welding.
Inferior arc-welding mode is adopted in described welding.
On the interior round week of described stator core sheet and end compressing tablet, all have several pyriform notches at interval, and some stator core sheets and the formed stator of two compressing tablet closed assemblies, it forms some axial peariform slots by the pyriform notch is stacked on interior round week.
The present invention forms some " W " shape welding grooves vertically owing to having adopted on stator core cylindrical circumference, by in " W " shape welding groove, fixing stator core with welding manner, substitute traditional some cramp grooves of processing on the cylindrical circumference of stator, put the fixed stator mode unshakable in one's determination of stator cramp in the groove, thereby make stator production efficiency be much improved, reduced employed material in the stator core manufacturing process, reduced cost, and make the mechanical strength of stator core and verticality precision to improve, improved the lamination coefficient of stator core sheet, make stray loss thus, core loss, eddy current loss reduces, the raising of motor performance and motor production efficiency, make efficient, the delivery efficiency of ultra high efficiency threephase asynchronous is compared traditional threephase asynchronous and has been improved 3%, and can save 1% cost, also make efficient, noise during the operation of ultra high efficiency threephase asynchronous obviously reduces, and prolongs efficient, the useful life of ultra high efficiency threephase asynchronous.
