Embodiment 1

[0017] as attached figure 2 As shown, the present invention is an anti-blackening wrapping method for electromagnetic wires, in which an insulating coating 2 made of insulating material is painted on the surface of the existing electromagnetic wires 1, so that the electromagnetic wires are fully wrapped when wrapped. It is isolated from the air, and then wraps the insulating tape 3 on it to form a composite insulation protection structure of the electromagnetic wire. After the wrapping insulating tape 3 is wrapped on the electromagnetic wire, the formed gap 4 and the electromagnetic wire are covered by the insulating coating 2 isolation. The said brushing a layer of insulating layer on the surface of the magnet wire refers to brushing a layer of resin as the main material on the surface of the existing magnet wire, which is based on polytetrafluoroethylene-ethylene copolymer with certain elastic shrinkage properties. For the coating made of materials, in order to enhance the...

Embodiment 2

[0019] A method for wrapping an electromagnetic wire to prevent blackening, in which an insulating coating made of insulating material is applied on the surface of the existing electromagnetic wire, so that the electromagnetic wire is completely isolated from the air when it is wrapped, and then The insulation tape is wrapped around to form a composite insulation protection structure for the magnet wire. The said brushing a layer of insulating layer on the surface of the magnet wire refers to brushing a layer of resin as the main material on the surface of the existing magnet wire. The main material is polyetherimide resin with certain elastic shrinkage properties. The layer is directly brushed on the electromagnetic wire by brushing, and then wrapped with insulating tape to form a composite insulating layer of insulating coating and insulating tape. The thickness of the coating is between 0.1-0.5 mm.

Embodiment 3

[0021] A method for wrapping an electromagnetic wire to prevent blackening, in which an insulating coating made of insulating material is applied on the surface of the existing electromagnetic wire, so that the electromagnetic wire is completely isolated from the air when it is wrapped, and then The insulation tape is wrapped around to form a composite insulation protection structure for the magnet wire. The said brushing a layer of insulating layer on the surface of the magnet wire refers to brushing a layer of resin as the main material on the surface of the existing magnet wire. The main material is polyarylsulfone resin and polyarylether with certain elastic shrinkage performance The coating made of materials such as ketone resin or polytetrafluoroethylene-hexafluoropropylene copolymer can be brushed or plasma sprayed with aluminum oxide coating; the thickness of the coating is between 0.1-1 mm.

Abstract

The invention discloses an electromagnetic wire manufacturing method capable of preventing blackening of electromagnetic wires. In the method, a layer of insulating coating made of an insulating material is coated on the surface of the traditional electromagnetic wire to make the electromagnetic wire completely insulated from the air when the electromagnetic wire is wrapped, then the electromagnetic wire is wrapped with an insulating belt, and thus, a combined insulating and protective structure of the electromagnetic wire is formed. Coating the layer of insulating coating on the surface of the electromagnetic wire is to coat a layer of insulating coating which is made by using a resin main material and has certain elastic contraction performance on the surface of the traditional elastic contraction, such as a coating made of a polytetrafluoroethylene-ethylene copolymer, a polyetherimide resin, a polyarylsulfone resin, a polyaryletherketone resin, a polytetrafluoroethylene-hexafluoropropylene copolymer and other materials and an alumina coating sprayed in a plasma manner; and the coating is 0.1 to 1 millimeter thick.

Description

technical field [0001] The invention relates to a structural improvement of motor parts, in particular to a method for wrapping electromagnetic wires of a motor, which is mainly suitable for use in wrapping electromagnetic wire insulation tapes. Background technique [0002] The stator of the motor is generally made of electromagnetic wire wound into a coil and then embedded in the iron core slot made of silicon steel sheet; in order to ensure the insulation performance of the electromagnetic wire, it is necessary to wrap the original electromagnetic wire with insulating tape when making the electromagnetic coil. Then impregnate the insulating varnish, and after drying, embed it into the iron core to form the stator coil. [0003] The quality of the insulating tape wrapped around the magnet wire will directly affect the insulation performance of the magnet wire. After the motor magnet wire produced by the general factory is stored for a period of time, a thin uneven black f...
