Continuous reeling shaping processing technology is to determine connected continuous punching semi-finished product linearly in sheet material blank upper punch, the half-finished lateral edges of punching has several notch iron core teeth (21) continuously, notch iron core teeth (21) cross section is I-shaped, there is a location notch two (17) on the top of each notch iron core teeth (21), and the inside edge of adjacent notch iron core teeth (21) is connected to each other; Continuous punching semi-finished product continuous reeling spirality, the continuous punching semi-finished product that experience is not reeled are called notch core stamping straightway (23), the continuous punching semi-finished product that experience is reeled are called notch core stamping curved section (24), between some ring recess mouth core stamping curved sections (24) and notch core stamping straightway (23), cut off, the some ring recess mouth core stamping curved sections (24) after cutting off experience to laminate is again processed into notch iron core (4).
3. the concentric partition type stator of one according to claim 1 and stator winding are concentrated assembling method, the technical process that it is characterized in that the concentrated assembling method of stator winding is: coiling stator winding on coil winding machine, insulation cushion between each winding straight flange (16) outer surface integument of the good stator winding of coiling, and make between layer insulation pad bonding firm; Winding overhang (15) and winding straight flange (16) to stator winding in shaping mould are moulding, and the at room temperature insulating varnish of dry solidification voluntarily of spray; Make the spacing of two winding straight flanges of stator winding (16) approximate the winding length of span of calculating with main stator iron core (7) diameter of bottom land place (19) simultaneously; After the insulating varnish dry solidification of spray on stator winding, take out stator winding for subsequent use;
Mounting groove insulation cushion (8) in several stator slots (9) of main stator iron core (7), and the flanging of slot liner pad (8) (14) is opened, the cross section of slot liner pad (8) is taken the shape of the letter U;
In main stator iron core (7) and slot liner pad (8), whole stator winding is installed successively; In the time that the winding straight flange (16) of stator winding is positioned at the notch place (18) of main stator iron core (7), to two winding straight flanges (16) of stator winding center extruding stator winding, make the spacing of two winding straight flanges of stator winding (16) equal the winding length of span of calculating with main stator iron core (7) diameter of notch place (18); Two winding straight flanges of stator winding (16) are pushed in the slot liner pad (8) in the stator slot (9) of main stator iron core (7); Because the spacing of two winding straight flanges of stator winding (16) is greater than the length of span of notch place (18); Stator winding after assembling can not come off from stator slot (9);
If stator winding belongs to individual layer chain type winding or individual layer Concentrical winding, each stator winding is installed successively; If stator winding belongs to two layer winding or single two-layer hybrid formula winding, in the time of assembling, whole lower floor's windings (3) must be first installed, whole upper strata windings (2) is finally installed;
After whole stator winding has assembled, the flanging (14) of whole slot liner pads (8) is turned back and covers winding straight flange (16), and make between two flangings (14) lap bonding firm;
In frock clamp, notch iron core member is arranged on to main stator iron core (7) radially inner side vertically, notch iron core member is concentric with main stator iron core (7) inner radial surface; The location notch one (11) on each stator tooth of main stator iron core (7) (10) top is alignd with the location notch two (17) at corresponding cage type support (5) radial outside edge, and the location notch one (11) on each stator tooth of main stator iron core (7) (10) top is alignd with the location notch two (17) on notch iron core teeth (21) top; Stator tooth (10) inner radial surface of notch iron core member radially-outer surface and main stator iron core (7) is interference fits or interference fit; Every several stator tooths (10), in location notch one (11) and location notch two (17), insert alignment pin (6); Alignment pin (6) can stop notch iron core member to move axially and radial rotating;
By the winding leads (20) of each stator winding, the stator winding serial or parallel connection that belongs to homophase or homopolarity together, and weld electric electromechanics source terminal; Between the winding overhang (15) of two-phase stator winding, insert end phase insulation pad respectively, tie up afterwards winding overhang (15); Finally concentric partition type stator dipping, make together with stator winding is adhesively fixed with main stator iron core (7) with notch iron core member.
