Embodiment Construction

[0018] A motor winding processing technology, comprising the following steps:

[0019] (1) Preparation: After the impregnation process of the winding stator core is completed, the winding stator core will be laid down;

[0020] (2) Glue coating: 8012 binder A, 8012 binder B and diluent are prepared into silicone rubber resin. The preparation method is: 8012 binder A and 8012 binder B in a weight ratio of 1:1, Add no more than 5% of the total weight of diluent, and the silicone rubber resin obtained after preparation is evenly applied to the winding end of the winding stator core with a paint brush, and the inside and outside of the winding end must be completely coated. In order to avoid collision and adhesion between the end of the coated winding and the end, causing peeling;

[0021] (3) Put into the box: Hang the coated winding stator core into the paint cage, then hang the paint cage into the oven trolley and drop it, then push the trolley into the UA electric blast dryin...

Abstract

The invention discloses a processing technology for a motor winding. The processing technology for the motor winding comprises the steps of preparing, gluing, placing into a box, drying, cooling, checking and the like. The processing technology for the motor winding mainly comprises the following steps of: after a winding stator iron core paint-dipping technology is finished, preparing silicon rubber resin from an 8012 adhesive A, an 8012 adhesive B and diluent, wherein the weight ratio of the 8012 adhesive A to the 8012 adhesive B is 1:1 and the amount of the diluent is not more than 5 percent of the total weight of the materials; painting the silicon rubber resin obtained through preparation on the winding end part of the winding stator iron core uniformly by using a paint brush; placing into a drying box at the temperature of 120 DEG C and preserving heat for 2 hours; after cooling, brushing the winding end part, which is dried, by using a brush; and checking. The processing technology for the motor winding has the advantages of improving moisture resistance, heat resistance, heat conductivity, electrical properties, mechanical properties and chemical corrosion resistance of the motor.

Description

technical field [0001] The invention relates to the field of motor winding processing technology, in particular to a processing technology for coating the end of the motor winding with silicone rubber resin. Background technique [0002] In the current motor production process, the motor winding stator core is usually dipped in paint and dried before entering the next assembly process. [0003] The motors produced by such processing technology have the most faults in use, such as winding breakdown, winding short circuit, winding open circuit, winding burnout, etc. These are all motor insulation problems. During the process of starting, running and stopping the motor, the insulating material should bear the impact of electromagnetic vibration and mechanical vibration, and also be corroded by moisture, dust, salt spray in the air and corrosive gas or liquid droplets in the working environment, and withstand the The aging of heating conditions, so the life of the motor mainly ...
