Problems solved by technology

In order to reduce the production cost, the manufacturer will replace the enameled wire conductor material of the stator coil with aluminum wire. Although it can reduce the production cost, when the enameled wire of the stator coil is connected with the power wire, the overlapping winding method is usually adopted, that is, the enameled wire is first 1. Remove the insulating layer on the surface of the conductor of the power line, so that the conductors of the two are exposed separately, and then the exposed conductors of the two are overlapped with each other, and finally rotated and wound, so as to complete the docking of the enameled wire of the stator coil and the power cord. The butt connection method is easy to cause the aluminum wire conductor to be exposed, and the exposed aluminum wire conductor is easy to cut off, or contact with the outside air to cause oxidation, resulting in short circuit of the motor and failure to work, poor stability and short life

Embodiment Construction

[0027] The conductive connection method of the motor coil includes a power wire and an enameled wire wound on the motor stator; the conductor of the power wire is a copper wire, and the conductor of the enameled wire is an aluminum wire; wherein, the conductive connection method between the power wire and the enameled wire Include the following steps:

[0028] Step 1: Remove the insulation layer at the end of the power wire and the enameled wire respectively, so that the copper wire bundle and the aluminum wire are exposed respectively;

[0029] Step 2: Divide the copper wire bundle into two strands, one of which is an integral copper wire bundle, and the overall copper wire bundle and the aluminum wire are rotated and wound to form a copper-aluminum winding wire bundle;

[0030] Step 3: Disperse the other copper wire bundle to form several mutually dispersed copper wires, and then wrap several scattered copper wires on the surface of the copper-aluminum winding wire bundle to...

Abstract

The invention relates to a conductive connection method of a motor coil. The motor coil comprises a power line and an enameled wire wound on a motor stator; and the conductor of the power line is a copper wire, and the conductor of the enameled wire is an aluminum wire. The copper wire is divided into an integral copper wire harness and a plurality of scattered copper wires, the integral copper wire harness and an aluminum wire are rotationally wound to form a copper-aluminum wound wire harness, the scattered copper wires are used for wrapping and winding the surface of the copper-aluminum wound wire harness to form a copper-aluminum wrapped wire harness, and then an opening in the lower end of a copper sleeve is used for fixedly clamping and pressing the copper-aluminum wrapped wire harness, a cavity is formed in the copper sleeve, a tin liquid flows into the copper sleeve, air in the copper sleeve is exhausted, welding between the copper sleeve and the copper-aluminum wrapped wire harness is completed, the copper-aluminum wrapped wire harness located in the copper sleeve is in a vacuum state, the aluminum wire is prevented from being exposed, the problem that the aluminum wire is easy to cut off or is oxidized due to contact with external air is reduced, and the conductive connection stability and the service life between the copper wire and the aluminum wire are improved.

Description

technical field [0001] The invention relates to a conductive connection method for motor coils. Background technique [0002] During the production of the motor, the enameled wire of the stator coil needs to be connected with the external power line after being wound. Among them, the conductor of the enameled wire of the stator coil and the conductor of the power line are usually copper wires. Since both are copper wires, the production cost Very high. In order to reduce the production cost, the manufacturer will replace the enameled wire conductor material of the stator coil with aluminum wire. Although it can reduce the production cost, when the enameled wire of the stator coil is connected with the power wire, the overlapping winding method is usually adopted, that is, the enameled wire is first 1. Remove the insulating layer on the surface of the conductor of the power line, so that the conductors of the two are exposed respectively, and then the exposed conductors of t...
