发明名称 ELECTRICALLY INSULATED WIRE
摘要 An electrically insulated wire includes a rectangular conductor having a substantially rectangular cross section with corners shaped in a circular arc, and an electrical insulating coating formed by heating an electrical insulating varnish applied to coat an outer periphery of the rectangular conductor. The electrical insulating coating includes a thickest portion and a thinnest portion in a peripheral direction thereof. The rectangular conductor has a curvature radius of the corners of 0.6 mm or less and a ratio L2/L1 of 2.0 or less where L1 is a length of a short side in a width direction and L2 is a length of a long side in a longitudinal direction. The electrical insulating coating has a ratio d1/d2 of 1.3 or less where d1 is a coating thickness of the thickest portion and d2 is a coating thickness of the thinnest portion in the peripheral direction of the electrical insulating coating.

主权项 1. An electrically insulated wire, comprising: a rectangular conductor having a substantially rectangular cross section with corners shaped in a circular arc; and an electrical insulating coating formed by heating an electrical insulating varnish applied to coat an outer periphery of the rectangular conductor, the electrical insulating coating including a thickest portion and a thinnest portion in a peripheral direction thereof, wherein the rectangular conductor has, in cross sectional shape, a curvature radius of the corners of 0.6 mm or less and a ratio L2/L1 of 2.0 or less where L1 is a length of a short side in a width direction and L2 is a length of a long side in a longitudinal direction, wherein the electrical insulating coating has a ratio d1/d2 of 1.3 or less where d1 is a coating thickness of the thickest portion and d2 is a coating thickness of the thinnest portion in the peripheral direction of the electrical insulating coating.
