Embodiment 1

[0024] The coating method of the coil of the stator core based on the thermoplastic tube includes the steps:

[0025] The thermoplastic tube selection step is to select a section of the thermoplastic tube 20 into which the coil 30 can be inserted, and the length of the thermoplastic tube 20 is greater than the long side of the coil 30. The thermoplastic tube 20 is an ATM-type thermoplastic tube 20 (also called a heat shrinkable tube) produced by Dongguan Guilin Electronic Materials Co., Ltd., and the material is PE+PA. The length of the thermoplastic tube 20 is mainly determined according to the long side (or diameter) of the coil 30. In particular, since the shape of the coil 30 can be either a rectangle or a circle, the rectangle is selected in this embodiment, so the long side is specially described. In other embodiments, a circular coil 30 can be used.

[0026] In the threading step, the coil 30 is inserted into the thermoplastic tube 20, and the connecting wires 11 at both e...

Embodiment 2

[0038] Compared with Example 1, the only difference is that sealant is applied to the cut-out position of the heat shrinkable tube. The sealant is 8518-D01 waterproof and insulating mortar produced by Lianjie Chemical (Kunshan) Co., Ltd., which can achieve a better sealing effect.

Abstract

The invention belongs to the field of generator or motor stator processing methods and provides a stator core cladding method based on a thermoplastic tube in order to solve low efficiency during the tensioning band winding of a conventional stator core. The method comprises a thermoplastic tube selection step of selecting a thermoplastic tube into which a coil can be inserted; an inserting step of inserting the coil into the thermoplastic tube and enabling a connecting line of both ends of the coil to pass through openings at both ends of the thermoplastic tube; a heating step of heating the thermoplastic tube; a cutting and sealing step of pressing and heating the thermoplastic tube located at the inner hole of the coil and then cutting the thermoplastic tube located at the inner hole of the coil; and a mounting step of embedding the core in the inner hole of the coil.

Description

Technical field [0001] The invention relates to the field of stator processing methods for generators or motors, and in particular to a method for coating stator cores. Background technique [0002] The stator core is the main component of a generator or motor. Among the existing stator cores, there is a stator core that includes a core and a rectangular frame-shaped coil (of course, it can also be of other shapes, but the commonly used one is a rectangle, that is, the coil is similar to a closed ring Shape, or rectangular frame-shaped structure), the coil is wound with a tension band. The material of the tension band is usually non-woven fabric, cotton or linen, etc. The tension band is fixed by winding in a circle Yes, the iron core includes a core body and a plate body. The core body is located at the gap in the center of the coil. The plate body is located on one side of the coil. The core body and the plate body are integrally formed. The iron core is provided with a throug...
