INSULATED ELECTRIC WIRE AND MOTOR

摘要

An insulated wire, containing a conductor, an insulating layer that directly or indirectly coats the outer periphery of the conductor and includes a foaming thermosetting resin, and an outer non-foamed insulating layer that directly or indirectly coats the outer periphery of the insulating layer, wherein the insulating layer has a thickness deformation ratio of 15% or more and 50% or less upon applying a pressure of 1 MPa at 25°C, wherein the outer non-foamed insulating layer has pencil hardness of 4H or more, and wherein a ratio of thickness of the insulating layer to the outer non-foamed insulating layer is 20 : 80 to 80 : 20; and a motor, wherein the insulated wire is wound into a stator slot in a state in which pressure is applied in a direction for reducing the outer diameter of the insulated wire and a thickness of the insulating layer is reduced.
