Liquid-insulated rotary baking curing device and method for armature

Abstract

An armature liquid insulating rotating, baking and curing apparatus, and a rotating baking method. The ferromagnetic component of an armature is provided with multiple winding slots distributed along a circumferential direction thereof so as to embed the winding. The rotating, baking and curing apparatus further comprises an air sealing part. The air sealing part is capable of injecting air towards a slot opening direction of the winding slot. Under an air injection pressure function, the impregnated liquid can be prevented from flowing out of the winding slot under the effects of gravity so as to reduce the radial loss of the impregnated liquid along gaps among the winding slots during the subsequent paint dripping process and rotating, baking and curing process following a vacuum pressure impregnation process of an armature, improve filling and impregnating saturation rates of the impregnated liquid after impregnation, prevent formation of holes in internal gaps, first block the gaps where the impregnated liquid naturally flows out during the processes, and improve the capability of preventing moisture and other medium in external environment from intruding.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a liquid-insulated rotary baking curing device and a rotary baking method for an armature, so as to prevent loss and promote curing during the rotary baking process. Background technique [0002] Please refer to figure 1 , 2 , figure 1 A schematic diagram of the winding and its ferromagnetic components in the structure of the wind turbine, showing a part of the circumference of the entire ferromagnetic component, in the shape of a fan; figure 2 Construct a schematic diagram of a ferromagnetic component. [0003] The ferromagnetic part 100' of the armature is formed by stacking iron core laminations 100a', and the iron core laminations 100a' are, for example, silicon steel sheets or ferrite sheets, such as figure 2 As shown, the stacking direction is the axial direction of the final ferromagnetic component 100'. [0004] like image 3 as shown, image 3 It is ...

AI Technical Summary

Problems solved by technology

When dipping paint for the first time, in order to make the paint fill into the inside of the winding 200' better, the dipping time should be longer; the second dipping paint is mainly to form a surface paint film, on the other hand, if the second If the time for the first dipping paint is too long, the paint film of the first dipping paint will be damaged instead, and a good dipping paint effect will not be obtained.

There is also a contradiction in the time scale during the two paint dripping processes, which not only affects the amount of paint loss, but also affects the amount of paint on the inner and outer surfaces of the second dipping paint core

The amount of paint hanging is small and there is no need to scrape the paint. However, there must be gaps in the slot insulation, which may cause water ingress and moisture inhalation to damage the insulation (the so-called "breathing phenomenon" of porous insulating materials in the slot)

[0036] All in all, when the traditional winding 200' and the ferromagnetic component 100' are insulated, there is a contradiction. If the varnish can penetrate well, the loss of the varnish cannot be prevented; if the loss of the varnish is reduced, it is difficult for the varnish to penetrate well.
