Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that in today’s society, more and more attention is paid to environmental protection. When using the varnish dipping process to produce stators, the insulating varnish is easy to volatilize and produce toxic gases during the production process. It is necessary to configure pollution treatment equipment to timely and effectively To deal with poisonous gas, but the pollution treatment equipment is relatively expensive, which is not conducive to the control of the production cost of the motor

Abstract

This application relates to a special tooling for epoxy perfusion of motor stators, which includes a base, an inner core and a top plate, the base is in the shape of a disc, and the top surface is set horizontally; the inner core is a solid cylinder, and is coaxially connected to the upper end of the base The top plate is in the shape of a disc, on which there is a coaxial installation hole, which is used for coaxial socketing to the outer circumference of the upper end of the inner core, and the inner circumference of the installation hole fits the outer circumference of the inner core, and there is also a set on the top plate There are filling holes. When insulating the stator, firstly insert the stator into the motor casing, then place the motor casing vertically on the base, and make the stator sleeve on the inner core, then inject the ring from the upper end of the motor casing Epoxy resin is used to cover the stator with epoxy resin to realize the insulation of the stator. During this process, the inner core occupies a certain space, which is used for the installation of the rotor.

Description

technical field [0001] This application relates to the field of motor production, in particular to a motor stator epoxy perfusion method and its special tooling. Background technique [0002] Motor stators are an important part of motors such as generators and starters. refer to figure 1 , the stator is coaxially embedded in the motor housing 11 , and usually the outer circumference of the stator is an interference fit with the inner circumference of the motor housing 11 , and the stator mainly includes an iron core 12 and a winding 13 . The winding 13 is a general term for a phase or the entire electromagnetic circuit formed by a plurality of coils or coil groups. [0003] After the stator is assembled, it usually needs to be insulated, that is, dipped in paint, drained, dipped in paint again, and finally placed in an oven for drying to coat the stator with insulating paint to meet the insulation requirements of the stator. [0004] In view of the above-mentioned related...
