Abstract
The invention relates to a split stator core and a manufacturing method thereof. The split stator core is composed of a plurality of iron core units which are spliced into a circular ring core; the split stator core is characterized in that each iron core unit is composed of an iron core yoke part and two half-tooth parts; two half-tooth parts are symmetrically arranged at two ends of each iron core yoke part; and the end surfaces of the half-tooth parts of the adjacent two iron core units contact with one another to form an intact iron core tooth part. According to the split stator core, the structural design is relatively reasonable; the motor performance is significantly improved; and raw materials of iron core stamping sheets are reduced, or even a large-volume iron core can also be spliced by small iron core sheets of leftover bits and pieces.
Description
Technical field
The present invention relates to motor stator, particularly a kind of assembled piece type stator core and manufacture method thereof being applicable to the winding mode of concentratred winding single-phase brushless DC motor.
Background technology
The iron core great majority of traditional motor stator are all use overall circular punching material to fold riveting to form, but the stator core of this kind of structure exists the low problem of circular iron-core lamination stock utilization, compare waste iron-core lamination raw material.。
Manufacture method unshakable in one's determination and the core device disclosed in unshakable in one's determination and CN1391330 of a kind of electric rotary machine disclosed in CN1178410, all solve the problems referred to above of conventional motors stator core, it is built up multiple independent stack of lamination by some iron core splicing sheets, then direct by copper wire winding on independent stack of lamination, again each stack of lamination is coupled together and form stator core overall structure, its punching stock utilization height does not waste iron-core lamination raw material, but all there is following defect in both: the yoke portion of adjacent stack of lamination closes up the stator core being spliced into entirety mutually, namely independent stack of lamination has independent teeth portion, yoke portion is provided with splicing construction.When such spliced stator core structure is applied to concentratred winding single-phase brushless DC motor, because the seam crossing of splicing concentrates the yoke portion passed through at magnetic induction line, the existence of this seam can block magnetic induction line, has a strong impact on motor performance.Even and if this spliced iron core is after winding winds, connection to each other neither be very firm, just can reliably connect after needing to be fixed by external hoop.
Summary of the invention
The present invention want technical solution problem be to provide a kind of structural design more reasonable, significantly improve motor performance and save iron-core lamination raw material, even also can be combined into assembled piece type stator core and the manufacture method thereof of large volume iron core with the tailing lamination of fritter.
Technical scheme of the present invention is:
A kind of assembled piece type stator core, be made up of the multiple core unit piecing together circular iron core, it is characterized in that: the half measure-alike teeth portion that described core unit is symmetrically set in rear of core two ends by rear of core and two forms, half teeth portion end face of two adjacent core unit contacts the complete core tooth part of formation one.
A manufacture method for above-mentioned assembled piece type stator core, is characterized in that, comprise the steps:
1), stamping-out is shaping, utilize blanking die the stator iron-core lamination material stamping-out of full wafer to be become multiple mutual independently stator iron-core lamination unit, measure-alike sheet half teeth portion that described stator iron-core lamination unit is symmetrically distributed in sheet rear of core two ends by sheet rear of core and two forms;
2), foldedly admittedly core unit is become, multiple stator iron-core lamination unit after stamping-out are folded riveting to stator core required thickness, stator iron-core lamination unit is overlapped formation core unit, form the block rear of core of core unit after sheet rear of core overlaps, after sheet half teeth portion overlaps, form bulk half teeth portion of core unit;
3), stator core is pieced together, the bulk half teeth portion end face of multiple core unit contacts and forms a circle, in the process by stator core coiling stator, the electromagnetic wire of winding tightly adjacent two core unit are turned to one in two bulk half teeth portion, after coiling completes, whole stator core is fixed as one.
The invention has the beneficial effects as follows: the split seam due to this assembled piece type iron core is positioned at the center of stator teeth, magnetic circuit close to split seam position time turn to sew up with split closely parallel, then split seam can not cut off magnetic circuit, compared with conventional stator core, the tailing lamination of stator iron-core lamination stock utilization height fritter also can be combined into large volume iron core, compared with existing assembled piece type stator core, when independent winding, magnetic induction line is not cut off, significantly improve magnetic property, and the Mechanical Structure Strength that the consolidation of winding only need not be relied on just can to make whole stator reach desirable by external hoop.
