Title:
INSULATED ELECTRIC WIRE AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2014/123122
Kind Code:
A1
Abstract:
Provided is an insulated electric wire comprising a conductor, an insulation layer including a foam heat-curable resin and which covers the outer circumferential surface of the conductor, and an outside non-foam insulation layer that covers the outer circumferential surface of the insulation layer. The thickness deformation rate of the insulation layer when a pressure of 1 MPa is applied at 25°C is 15%-50%. The pencil hardness of the outside non-foam insulation layer is at least 4H and the ratio between the insulation layer thickness and the outside non-foam insulation layer thickness is 20:80-80:20. Also provided is a motor having this insulated electric wire wound around a stator slot, in a state in which pressure is applied in the direction in which the outer diameter of the insulated electric wire decreases, and the thickness of the insulation layer is reduced.
