Embodiment

[0015] see figure 1 with figure 2 , this embodiment is to provide a kind of easy processing, good packaging performance, which is beneficial to the heat dissipation of high-power devices, increase the power, and can ensure the firmness and optimal thickness of the stator group of the motor. Process, its process steps include as follows:

[0016] (1) Preheating of the motor frame 1: first, preheat the motor frame in an oven at a temperature of 80° C. for one hour, so as to facilitate the installation of the stator assembly and the pouring of the potting glue.

[0017] (2) The positioning and installation of the stator assembly 2; then put the stator assembly 2 into the motor frame 1, the outlet line of the stator assembly 2 is pressed into the stator core groove of the motor frame 1, and the stator core The groove is U-shaped, which is convenient for the installation and position positioning of the stator assembly.

[0018] After the stator assembly 2 is positioned and fixe...

Abstract

The invention discloses a process for encapsulating a stator coil in a motor. The process comprises the following steps of: preheating a motor frame, and putting a stator assembly into the motor frame to position and fix the stator assembly; arranging a pouring jig inside the stator assembly; and preheating the stator assembly which is loaded in the motor frame again, pouring prepared pouring glue on an enameled wire on the edge of the stator assembly to make the pouring glue flow into a stator, putting into an oven for baking when the poured pouring glue does not generate air bulbs, fully hardening the pouring glue to form an enclosed layer, and thus obtaining a finished encapsulation product. The process is high in heat conductivity, contributes to heat radiation, power promotion and cost reduction of a high-power device and is suitable for large scale production; furthermore, an epoxy injection molding process is finished in the encapsulating process, and the stator coil is easy to encapsulate, so that the sealing firmness and the optimal thickness of the pouring glue for the stator assembly of the motor are ensured.

Description

technical field [0001] The present invention relates to a packaging process, in particular to a packaging process for packaging a stator coil in a motor. Background technique [0002] Generally, there are two coil impregnation methods in the manufacturing method of the stator coil of the high-voltage rotary motor, that is, the stator coil is impregnated with resin in a single piece, and then heated and cured by hot pressing, and then assembled in the stator core slot and connected. The single-piece impregnation method and the overall impregnation method that put the stator coil before resin impregnation into the stator core slot and connect the wires, and then perform resin impregnation and curing. As far as the overall method is concerned, since the stator coil and the stator core are tightly consolidated after being impregnated with resin, the overall mechanical rigidity of the coil is high, and the thermal impedance between the stator coil and the stator core is higher th...
