ッ力■、！型材■等を除去する。The stator winding (■) is inserted into the groove () of the stator core (■), and the end outside the groove is tied with a string (■) to fix the movement of the end. A packer ■ having a slope on the inner diameter side is brought into contact near both axial ends of the outlet of the core groove ■ of the stator winding ■ through a release material such as Teflon ■, and the slope surface (c) of this packer ■ is A presser ring (1) with a slope corresponding to the slope is brought into contact with the presser ring (1), and a turnbuckle (1 (1)
) and operate this turnbuckle to release the presser ring■
is pushed outward in the axial direction to generate a radial pushing force on the packer (2), which presses the stator winding (2) against the bottom of the groove (1). Next, after impregnating and hardening the wire-wound core with resin using a full impregnation method, the turnbuckle (1 (1), presser ring (9), padding ■, !shape ■, etc.) are removed.
