PURPOSE:To prevent an interpole connection wire from being broken due to the operation of a machine, by setting a V-formed elastic retaining body between the sagging section of the interpole connection wire bent by laminating a plurality of copper sheets, and a shell-covered insulation. CONSTITUTION:Field windings 4 protruded from a body are retained by a retaining ring 2. A shell-covered insulation 3 for insulation is set between the retaining ring 2 and the field windings 4. The interpole connection section 5 of laminated copper sheets is provided with a sagging section 5a bent on the center, and by brazing or the like, the both ends are fixed to the top turns 4a of the field windings 4 in adjacent contact with each other. In a space formed between the sagging section 5a of the interpole connection wire 5 and the shell- covered insulation 3, a V-formed elastic retaining body 6 is set so that the opening section may be arranged on the side of the outer diameter. By this structure, the elastic retaining body 6 can easily cope with a reciprocating movement in the peripheral direction of the interpole connection wire due to the operation-stop of a machine, and the interpole connection wire is prevented from being broken. |
