Armature liquid insulating rotary baking and curing apparatus and method

Abstract

The invention discloses an armature liquid insulating rotary baking and curing apparatus and a rotary baking method. A ferromagnetic part of an armature is provided with a plurality of winding slots into which windings can be embedded, the winding slots are arranged along a circumferential direction of the ferromagnetic part, the rotary baking apparatus also comprises an air seal part, and the airseal part can be used for injecting air towards slot openings of the winding slots. Under pressure caused by air injection, impregnation liquid can be prevented from flowing out from the winding slots under the effects of gravity; radial loss of the impregnation liquid along slit openings between the winding slots can be reduced in paint trickling processes and rotary baking and curing processesfollowing vacuum pressure impregnation of the armature; filling and impregnating saturation rates of the impregnation liquid can be improved after impregnation operation, cavities can be prevented from being formed in internal slit openings, slit openings via which the impregnation liquid naturally flows out can be blocked first during the processes, and capability of preventing intrusion of moisture and other mediums in external environment can be improved.

Description

Technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to an armature liquid-insulated rotary baking curing device and a rotary baking method, so as to prevent loss and promote solidification during the rotary baking process. Background technique [0002] Please refer to figure 1 , 2 , figure 1 It is a schematic diagram of the winding and its ferromagnetic components in the wind turbine structure, showing a part of the entire ferromagnetic component circumference, which is fan-shaped; figure 2 Schematic diagram of ferromagnetic components. [0003] The ferromagnetic part 100' of the armature is formed by stacking iron core laminations 100a'. 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 part 100'. [0004] Such as image 3 As shown, image 3 It is a schematic diagram of a single core lamina...

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 sur...
