摘要：
A tapered cage coil is prepared, having a small-diameter top coil end 101 and a large-diameter base coil end. The tapered cage coil is axially inserted into a stator core. Then, the tapered cage coil is radially expanded to thrust slot-accommodated portions of the coil into slots of the stator core. This can eliminate the necessity of deforming the base coil end to thereby facilitate the manufacturing procedures. At the same time, possible spring back can be mitigated.
