Abstract

A resin composition ( 601 ) containing the following is prepared: a base unsaturated-polyester resin and/or a base vinyl-ester resin; a base radical-polymerizable monomer; a radical-polymerizable monomer having a thermally latent isocyanate group; a photo-radical polymerization initiator; and an alkylborane and/or an alkoxyamine derivative. A stator coil ( 60 ) in a stator ( 20 ) in a dynamo-electric machine ( 10 ) is coated using said resin composition ( 601 ) only, i.e. just the one resin composition. An insulated coated section ( 29 A) and a conductor-exposing section ( 29 B) of a join-side coil end ( 62 ) are also coated using said resin composition ( 601 ).

Claims (17)

1. A member for a dynamo-electric machine, comprising a coil formed with an insulation coated conductor, wherein

the coil is coated using a resin composition containing:

a base unsaturated-polyester resin and/or a base vinyl-ester resin,

a base radical-polymerizable monomer,

a radical-polymerizable monomer having adhesiveness to the insulating film of the insulation coated conductor (hereinafter, referred to as adhesive radical-polymerizable monomer), and

a photo-radical polymerization initiator.

2. The member for a dynamo-electric machine according to claim 1 , wherein the coil is coated with only the resin composition.

3. The member for a dynamo-electric machine according to claim 1 , wherein the adhesive radical-polymerizable monomer contained in the resin composition is a radical-polymerizable monomer having a thermally latent isocyanate group.

4. The member for a dynamo-electric machine according to claim 1 , wherein the resin composition further contains an alkyl borane and/or an alkoxy amine derivative.

5. A dynamo-electric machine using the member for a dynamo-electric machine according to claim 1 .

6. A resin composition comprising:

a base unsaturated-polyester resin and/or a base vinyl-ester resin;

a base radical-polymerizable monomer;

a radical-polymerizable monomer having adhesiveness to an insulating film of an insulation coated conductor (hereinafter, referred to as adhesive radical-polymerizable monomer); and

a photo-radical polymerization initiator.

7. The resin composition according to claim 6 , wherein the adhesive radical-polymerizable monomer is a radical-polymerizable monomer having a thermally latent isocyanate group.

8. The resin composition according to claim 5 , further comprising an alkyl borane and/or an alkoxy amine derivative.
