Estimating the term…
An enameled wire capable of improving withstand lifetime with respect to the application of surge voltage of an inverter and thermal degradation thereof while restricting an amount of an inorganic filler material is provided. The enameled wire comprises an electrically conductive wire (11) and a coating (12) formed of a high molecular compound uniformly mixed with an inorganic filler material in the form of fine flat particles provided around the electrically conductive wire (11). The enameled wire may comprise an electrically conductive wire (21), a coating (23) formed of a polyester imide resin solution mixed with an inorganic filler material in the form of fine flat particles and provided on the conductive wire and a coating (24) formed of polyamide imide and provided on the coating (23).
An enameled wire comprising an electrical conductive wire and a coating layer formed of a high molecular compound and an inorganic filler material in the form of fine flat particles uniformly dispersed in said high molecular compound.
An enameled wire comprising an electrical conductive wire, a first coating layer surrounding said electric conductive wire, said first coating being formed of a high molecular compound of polyester imide resin solution and an inorganic filler material in the form of fine flat particles uniformly dispersed in said high molecular compound, and a second coating of polyamide imide formed on said first coating layer.
An enameled wire comprising an electrically conductive wire, a first coating provided on said electrically conductive wire, said first coating being formed of polyester imide resin, and a second coating layer formed on said first coating layer, said second coating layer being formed of polyamide imide mixed with an inorganic filler material in the form of fine flat particles uniformly dispersed therein.
