Bonding and potting method for aerial integrated motor

Abstract

The invention relates to a bonding and potting technology method for an aerial integrated motor, wherein the method covers a bonding method, preparation of a potting material for an elastic film, a potting die and a potting method. According to the invention, an elastic film is employed as a carrier and a characteristic of shape expansion by squeezing is utilized, so that an end commutator is isolated from an adhesive and a potting material and it can be ensured that there is no superfluity at the surface of the commutator after the bonding and potting processing; meanwhile, an axiality after the potting processing can also be ensured. Besides, the elastic film comprises the following components according to mass percentage: 100% of GN 521 raw material; 100% of a GN 521 vulcanizing agent; and 10% to 50% of a filler. According to the invention, bonding and potting production and processing problems of an aerial integrated motor are solved and a purpose that a circularity of a commutator meets a requirement after the bonding and potting processing of the aerial integrated motor can be achieved; meanwhile, an effect that the surface of the commutator on the winding is free of gel after the bonding and potting processing is realized; and a defect of a circularity deviation of an inserted motor can be overcome.

Description

technical field [0001] The invention relates to a bonding and potting method, in particular to a bonding and potting method for an aviation integral motor. Background technique [0002] The structure of the traditional motor commutator is a plug-in type, see the attached figure 1 After the stator and rotor are wound, the commutator 1 is installed to become the winding 2, and the potting mold is used for potting, and finally assembled with reeds and other parts to form a motor. The defect is that the commutator is not round enough to cause commutation sparks Larger, it is easy to affect the product performance, so a new type of integral motor was invented, that is, the structure of the integral motor is shown in the appendix of the manual. figure 2 , the end face commutator is used, the process flow is to wind the stator and weld it directly with the commutator to form a stator winding, and then bond the component to the shell, the coaxiality depends on the bonding The fix...
