If stator winding belongs to monolayer chain type winding or monolayer Concentrical winding, each stator winding is installed successively；If stator winding belongs to Double Layer Winding or single two-layer hybrid formula winding, when 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 insulation pads (8) is turned back and covers winding straight flange (16), and make between two flanging (14) laps bonding firmly；
In frock clamp, notch iron core member being axially mounted to main stator iron core (7) radially inner side, notch iron core member is concentric with main stator iron core (7) inner radial surface；Make the locating slot one (11) on main stator iron core (7) each stator tooth (10) top align with the locating slot two (17) at corresponding cage type support (5) radial outside edge, and make the locating slot one (11) on main stator iron core (7) each stator tooth (10) top align with the locating slot 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 locating slot one (11) and locating slot 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, belonging to the stator winding serial or parallel connection of homophase or homopolarity together, and weld motor power lead-out wire；Between the winding overhang (15) of biphase stator winding, insert end phase insulation pad respectively, tie up winding overhang (15) afterwards；Finally concentric partition type stator dipping, make together with stator winding is adhesively fixed with notch iron core member and main stator iron core (7).
