Example Embodiment

[0016] See attached figure 1 As shown, an enameled wire for motor windings includes a magnetically permeable core 4 and an insulating layer 3 covering the outer surface of the magnetically permeable core 4. The insulating layer 3 is coated on the outer surface of the copper layer 2 It is formed of polyester or polyurethane or polyimide. The magnetically permeable core 4 includes a steel core 1 and a copper layer 2 covering the outside of the steel core 1. The copper layer 2 is coated on the outside of the steel core 1 by an extrusion method. The steel core 1 is preferably Q195 steel with good permeability. Steel has magnetic properties, so it can play a role in magnetic permeability, increase the tensile strength of the enameled wire and improve the mechanical properties of the enameled wire; copper has excellent conductivity and corrosion resistance, so it can improve the conductivity and protect the inner layer The role of steel core.

Abstract

The invention relates to a lacquered wire for a motor winding. The lacquered wire comprises a magnetic conductive core body and an insulating layer coated outside the magnetic conducive core body, and the magnetic conductive core body comprises a steel core and a copper layer coated on the outer side of the steel core. The insulating layer is made of polyester or polyurethane or polyimide. The copper layer is coated on the outer side of the steel core through the extrusion method. The steel core is made of No. Q195 steel. The lacquered wire for the motor winding not only has high strength and high heat resistance of the steel, but also has high electrical conductivity and good anti-corrosion performance of copper. The lacquered wire has good magnetic conductivity and excellent high frequency property and has the advantages of fast magnetic conduction and smooth startup of a motor when being applied on the motor winding; furthermore, due to the adoption of the dual-metal material, the price is lower than that of the traditional pure copper lacquered wire, the purpose of reducing the cost is achieved, and the copper resources are saved.

Description

Technical field [0001] The invention is the field of electrical materials, which involves a lacquer bag for motor winding. Background technique [0002] The lacquer cable is a major variety of motor winding wires. It is usually composed of copper parent line and insulation layer. Due to the large density and high price of pure copper, the motor winding made of pure copper lacquer wire has the disadvantages of poor heat resistance, large weight, and high cost.In addition, the traditional pure copper paint line has the characteristics of incompetence. When used as a motor winding, the main magnetic flux of the motor will be reduced and the motor startup speed will be reduced. Invention content [0003] The purpose of the present invention is to find a substitute for traditional pure copper lacquer packs, overcome the deficiencies, and propose a lacquer cable with a motor -conducting motor winding. [0004] In order to achieve the above -mentioned purpose, the technical solution ad...
