ELECTRICAL MACHINE STATOR MANUFACTURING PROCESS Russian patent published in 2002 - IPC

FIELD: electromechanical engineering; large electrical machines with insulated slot and end portions of winding. SUBSTANCE: winding conductors are placed in groups on auxiliary former according to their position in finally assembled core; auxiliary spacing members are also installed between groups of conductors. Teeth of electric steel segments are installed between mentioned groups while removing auxiliary members to assemble the core. Segment teeth are turned when mounting them in stator to set them apart from side edges of winding conductors. Disk with removable slide blocks is used for press-fitting the segments placed on split pressure rings. Upper pressure ring is mounted on assembled core and the latter is braced with aid of studs. Former, disk, taper members, and slide blocks are removed; winding conductors are finally secured with wedges. EFFECT: facilitated manufacture of stator. 3 cl, 2 dwg
