Claims
- 1. An insulated wire, which comprises at least one insulating layer formed by applying and baking, directly or on another insulating layer on a conductor, a resin composition containing at least one compound selected from the group consisting of a polyamidimide resin and a polyimide resin, each having, in the molecular structure of the resin, a structure represented by the following formula (I):wherein R1 is selected from the group consisting of a hydrogen atom, an alkyl group, a hydrogen group, a halogen atom, and an alkoxy group; R2 is selected from the group consisting of a hydrogen atom, an alkyl group, a hydroxyl group, a halogen atom, and an alkoxy group, and/or a resin composition containing at least one compound selected from the group consisting of a polyamidimide resin and a polyimide resin, each having, in the molecular structure of the resin, a structure represented by the following formula (II):wherein R3 is selected from the group consisting of a hydrogen atom, an alkyl group, a hydroxy group, a halogen atom, and an alkoxy group; R4 is selected from the group consisting of a hydrogen atom, an alkyl group, a hydroxyl group, a halogen atom, and an alkoxy group, and said insulated wire has a 0.2% yield stress of not more than 110 MPa.
- 2. The insulated wire as claimed in claim 1, wherein said 0.2% yield stress of the insulated wire ranges from 105 MPa to 93 MPa.
- 3. The insulated wire as claim in claim 1 or 2, wherein part or all of the insulating layers contains a repeating unit derived from a monomer component having the structure represented by the above formula (I), and/or a repeating unit derived from a monomer component having the structure represented by the above formula (II), in an amount of 20 mol % to 60 mol % in all repeating units.
- 4. The insulated wire as claimed in claim 1 or 2, wherein part or all of the insulating layers contains a repeating unit derived from a monomer component having the structure represented by the above formula (I), and/or a repeating unit derived from a monomer component having the structure represented by the above formula (II), in an amount of 40 mol % to 55 mol % in all repeating units.
- 5. The insulated wire as claimed in claim 1, wherein the surface of the outermost layer of the insulating layers has lubricity with a coefficient of static friction of not more than 0.1.
- 6. The insulated wire as claimed in claim 5, wherein the surface of the outermost layer of the insulating layers has a lubricating layer, the lubricating layer being formed by applying and baking a lubricating paint that contains a wax and a thermosetting resin, and that further contains a rosin-series resin and/or a maleic-series resin in an amount of 3 to 20 parts by weight, to 100 parts by weight, of the total solid content of the wax and the thermosetting resin.
- 7. A stator of a generator or a motor comprising the insulated wire of claim 1.
