Title: METHOD FOR MANUFACTURING ARMATURE, AND ARMATURE
Abstract:
An annular conductor holding device having a hold-guide part in which blades are circumferentially disposed across gaps in a cylindrical configuration is readied in a device preparation step (step S11). In a simple positioning step (step S12), annular conductors are inserted and positioned in two of the gaps so as to straddle a plurality of the blades. In an overlap positioning step (step S13), the next annular conductor is inserted into the gaps so as to partially overlap the previously positioned annular conductor. Step S13 is then repeated so that the annular conductors positioned in step S13 are positioned in a spiral shape on the hold-guide part. In a fitting step (step S14), the internal circumferential part of an iron core and the hold-guide part where the annular conductors are positioned are caused to fit, and the circumferential positions of the gaps and the slots in the iron core are aligned. In an insertion step (step S15), a pusher is inserted into the internal circumferential part of the hold-guide part, and the annular conductors are engaged, moved in the axial direction of the hold-guide part, and inserted into the slots in the iron core to form a coil.
