Pressure-storing device for armature liquid insulation rotation and baking solidification

Abstract

The invention discloses a pressure-storing device for armature liquid insulation rotation and baking solidification. The armature comprises a winding and an iron magnetic component. The iron magneticcomponent is provided with a plurality of winding slots which are arranged along the circumferential direction for embedding the winding. The pressure-storing device comprises a pressure-storing element, which has a plurality of fluid passages, through which air can blow towards the gap of the armature surface. The invention is advantageous in that under the effect of spray air pressure, dipping liquid can be prevented from flowing out from a slit under gravity; the loss of dipping liquid at the slit can be reduced during the paint dripping process after dipping subsequent to the vacuum pressure dipping process of the armature, and during the rotary baking process; the filling rate of dipping liquid after dipping can be increased, and the slit where the natural loss of dipping liquid occurs can be locked, and the capability of preventing moisture in the air and other medium in the external environment from invading can be enhanced.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a pressure accumulator for the rotation baking and curing of armature liquid insulation to prevent loss and accelerate curing during the rotation 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] Such as image 3 as shown, image 3 It is a...

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.
